An air heat exchanger is a device that is used to transfer heat between two air streams. It is commonly used in heating, ventilation, and air conditioning (HVAC) systems. The heat exchanger can be designed to allow the two air streams to be either separately or together.
Generally, we classify the air heat exchanger into Finned Tube Heat Exchanger, Plate Type Air Heat Exchanger, Seamless Pipe Air Heat Exchanger, Twisted Heat Exchanger, etc. according to its structure.
Air heat exchangers are commonly used for a variety of applications in the HVAC system, such as space heating, cooling, humidification and air circulation. In space heating applications, air heat exchangers are used to transfer heat from outside air to indoor air, in order to provide heat for the building. In cooling and air circulation applications, air heat exchangers are used to transfer heat from an indoor space to the outside. in order to keep the building cool.
The main advantage of using an air heat exchanger is that it is very efficient in transferring heat energy between the two streams without any loss. It is also relatively inexpensive, compared to other types of heat exchangers. Additionally, air heat exchangers are small and compact, making them ideal for applications in tight spaces.

In October, the miracle did not appear. After the industry's popular Dong Feng and VOLVO Group (Volvo) joint venture plan, this fall is still a mystery.
The reporter got news from the two companies. Dongfeng and VOLVO are actively discussing further cooperation plans. The relevant programs have been applied to relevant national policy departments. Although both parties have been in love for many years, it is not easy to really get together. VOLVO is already a group of wives and concubines in China. It needs to get rid of several Chinese "lovers" before it can be linked to the east wind.
VOLOV's new love
VOVOL first met with Dongfeng in 2003. In that year, Dongfeng started the research and development of heavy truck Tianlong. When Renault Trucks, a subsidiary of VOLVO, provided engine-related technology to Dongfeng, Nissan Diesel, another VOLVO company, transferred the cab technology to Dongfeng. The relevant data shows that Tianlong product sales show a good momentum of growth. The well-known automotive analyst Jia Xinguang believes that: Dongfeng Tianlong heavy truck integrated VOLVO's Renault, Nissan Diesel's technology, is an integrated innovative product, its success will inevitably further cooperation between the two into the depths.
In early 2004, VOLVO's Renault Trucks had signed an agreement with Dongfeng Motor Co., Ltd. in Paris. According to the agreement, the partners will establish a joint venture in China to produce truck and truck parts. However, the joint venture between the two parties was limited in June 2004 due to the joint venture with the new automobile industry policy. (Note: According to the new automobile industry policy, the same foreign company can only establish two domestic (including two) below the same production in the country. (Passenger and commercial vehicles—trucks and buses are commercial vehicles and motorcycles) are joint ventures for complete vehicle products.
Since then, VOLVO has not stopped this, he needs to make greater gains in the field of heavy trucks. After the deadlock with Sinotruk, the impulse came even stronger.
"There is no further news about the cooperation with Dongfeng." Zhang Wen, the VOLVO Group China Investment Co., Ltd., is responsible for public relations media. After VOLVO (China) repeated its remarks, the reporter finally received a reply from the VOLVO Group's exclusive official issue a few days ago. It clearly affirmed that Dongfeng Motor Group Co., Ltd., Nissan Motor Co., Ltd. and Swedish Volvo Corp. are investing in heavy and medium-sized Volvo companies. The possibility of commercial vehicle business is discussed in depth. At present, this business is operated by Dongfeng Motor Co., Ltd., a joint venture established by Dongfeng Motor Group and Nissan Motor Co. in China. Moreover, they are engaged in in-depth discussions with China’s relevant authorities.
Dong Jun, president of Dongfeng Motor Co., Ltd., told reporters cautiously: “Before there is no specific result, it is not convenient to disclose relevant information.†Liu Genshang, who is responsible for propaganda of Dongfeng Truck Co., Ltd., said: “Dongfeng and the Volvo Group's cooperation is being organized by the Group. Level of operation.†Obviously, further cooperation between the two sides is a fact, but they are still worried about the prospect of cooperation.
Complex Chinese Bureau
Before the introduction of the new automobile industry policy in 2004, the VOLVO Group already had Xi'an Volvo Bus Company, Shanghai Shenwo Bus Co., Ltd., and Huawo Truck Co., Ltd. in China. In addition to the comprehensive acquisition of Nissan Diesel this year, Dongfeng Nissan Diesel, which was established by Dongfeng and Nissan Diesel, is also included in the VOLVO joint venture list in China. VOLVO Group already owns four joint ventures for complete vehicles. "The VOLVO Group's joint venture relationship in China is complex. Now nobody can tell the prospects of his cooperation with Dongfeng," said Jia Xinguang, an automotive analyst.
In the field of passenger vehicles, in 1994, Volvo Group and Xi'an Aircraft Co., Ltd. established Xi'an Volvo Bus Co., Ltd. Then in 2000, SAIC Motor, Volvo (China) Investment Co., Ltd. (Vic) and Swedish Volvo Bus Company (VBC) invested in Shanghai Shanghai Sovereign Bus Company. Since then, the VOLVO Group has begun to focus on embedding its trucks in China.
After nine years of hard work with China National Heavy Duty Truck Group Corporation, Volvo finally established a joint venture Huawo Truck Co., Ltd. with China National Heavy Duty Truck in 2003 under strong cooperation from the National Development and Reform Commission and other departments. Although they have a hard time, their married life is not happy. After China’s marriage, CNHTC has been focusing its efforts on the development of autonomous engines. In 2005, when VOLVO learned that Sinotruck was carrying out its own engine project, he changed the idea of ​​establishing a joint venture engine company with CNHTC. In addition, due to the introduction of Steyr technology by China National Heavy Duty Truck over the years has been digested and absorbed well, coupled with the joint venture with VOLVO, even more powerful, and then launched its own brand "Hoover." But at this time, VOLVO thought that the name “Howard†borrowed the light of the joint-venture brand Huawo in sales, which was a performance of “sentiment is not specific†by Sinotruk. Even after China National Heavy Duty Truck renamed the HOWO brand as Hao Hao, the contradictions between the two sides have not been eliminated. At the beginning of 2006, the two sides re-examined the contradiction in the direction of the truck's strategic development, which in turn led to the full shutdown of Huawo. China National Heavy Duty Truck Group personnel confirmed to this reporter: “Hua Woo has stopped production and there is no plan to start construction at the moment.†At this time, VOLVO has strengthened its determination to expand outwardly. Among them, the most popular candidate is Dongfeng.
The third way
To achieve further cooperation with Dongfeng, it is necessary to unravel the current node one by one. Jia Xinguang said: "The biggest headache for the VOLVO Group is the relationship with China National Heavy Duty Truck."
A person of China National Heavy Duty Truck, who did not want to be identified, expressed dissatisfaction with the reporter: “The problem of Huawo is largely due to the Europeans’ old-fashioned, lack of understanding of the Chinese market, and anyway, the suspension of production has not had much impact on us. The joint venture relationship is not urgent for us.†In the past two years, the production and sales volume of China National Heavy Duty Truck has grown significantly, and its self-built engine plant has been able to meet its own development needs. "Actually, for China National Heavy Duty Truck, the delay time is also a good way. In the boom period of the industry, it is also to avoid creating opportunities for opponents." An analyst told reporters that in fact, this method has been in the heavy truck industry precedent. For example, in 2004, after the capital chain of Hunan Torch, the controlling shareholder of Chongqing Hongyan Zhongqi, broke, the Chongqing government had taken strong measures to cut off the marriage, but when the Hunan Torch took a procrastination tactic, eventually Hongyan Zhongqi until This year it re-established a joint venture with SAIC Iveco. In a short period of three years, the production and sales of Chongqing Hongyan Heavy Duty Truck has been left behind by Shaanxi Heavy Duty Truck.
If voluntary breakup with China National Heavy Duty Truck Group is unsuccessful, will VOLVO Group still find a breakthrough in Xiwo and Shenwo? Behind Shenwo is the powerful SAIC. SAIC successfully enters the heavy truck industry through cooperation with Iveco and Hongyan Zhongqi. From its perspective, it will definitely not easily dissolve the joint venture relationship with VOLVO and create a bigger chance for Dongfeng. An industry insider believes: “Only Xiwo’s strength is weak and there is a possibility of being acquired by Dongfeng Commercial Vehicle Company. This is also the only hope.â€
If Dongfeng is able to acquire Xiwo to its subsistence, both Nissan Diesel and Xiwo may be eligible for a joint venture. But he still can not go around this road Kane China National Heavy Duty Truck.
One feasible way is to first do the Dongfeng Nissan Diesel. In fact, during the period of conflict with China National Heavy Duty Truck, in 2006, VOLVO launched a plan to fully purchase Nissan Diesel. After arduous negotiations with Nissan Diesel's controlling shareholder Nissan, VOLVO has acquired 96% of Nissan Diesel in August of this year. Nissan Diesel also announced a delisting on the Tokyo Stock Exchange. VOLVO is about to implement Nissan. 100% of Chai's acquisition. Later, the relationship between VOLVO and Dongfeng Motor also indirectly changed. He virtually owned a joint venture truck company, Dongfeng Nissan Diesel.
Some analysts believe that Dongfeng Nissan Diesel Co., Ltd. may become the shell resource of VOLVO's cooperation with Dongfeng Motor Co., Ltd. Since Nissan Diesel and Dongfeng respectively own 50% of the shares of Dongfeng Nissan Chai Co., Ltd., VOLVO will not receive a lower proportion of revenue in the future than the newly established joint venture company. This kind of operation is obviously much simpler.
Of course, competitors also have their own judgments. Liu Keqiang, sales manager of Shaanxi Heavy Duty Truck Co., Ltd., said: "The heavy truck industry joint venture will hardly see results in the short term. A Steyr technology integrates the nation's heavy truck resources and digests it for more than a decade before it matures, even if VOLVO has All the products are introduced into the east wind, and the east wind digestion takes time. The most realistic thing for Dongfeng is to introduce a product platform, and this kind of revenue may be more obvious.â€
