  Two devices market surging, the market is bigger and bigger, more and more rich product. Refrigeration Express reporter learned that the two devices market common products including finned heat exchangers, shell and tube heat exchangers, plate heat exchangers, tube heat exchangers, tank heat exchanger and evaporative condensers , "micro-channel, parallel flow as rookie of the two markets began to appear in the market. In the products of these two devices, the finned heat exchanger and the micro-channel, parallel flow belongs to the air-cooled heat exchanger, the other is water-cooled heat exchanger. Despite the high stability of air-cooled heat exchanger, air conditioning and refrigeration market experts do not need to add water, but the heat exchanger for each type has its own characteristics, its unique advantages also decided to use the product type as well as the amount of market share.

  A finned heat exchanger: the vast technology mature markets finned heat exchanger longest development time to market of the two devices are widely used in air conditioners, refrigerators, heat pumps, cold storage refrigeration system. Refrigeration Express reporter understands, from National two devices market situation, finned heat exchanger, the highest market share, this may finned heat exchanger market demand. With the continuous development of the market continues to expand our air conditioning and heat pump industry, finned heat exchanger demand also continued to expand.

  Finned heat exchanger occupy the highest proportion in the more than two hundred of the nation, enterprise refrigeration Express reporter understands, because finned heat exchanger in the long-distance transport easy because external force caused by the products irreversible injury, so the long-distance transport requirements relatively high finned heat exchanger manufacturers across the country, in order to reduce transportation costs, and to facilitate the development of the refrigeration industry supporting. Domestic production of finned heat exchangers, joint, Melody Ko, Sanyo is a typical representative.

  Finned heat exchanger development for many years, the technology is more mature compared to other products, air conditioning and refrigeration market experts, the effect of the use of the finned heat exchanger has a close relationship with the fins and brass fins thickness, fin size of the area, the length of the brass, thickness will affect the finned heat exchange efficiency of the heat exchanger. The pros and cons of the fins and brass often deeply production equipment and raw materials, the technology is relatively mature finned heat exchanger industry, product quality is essential to grasp the raw materials and production equipment.

  2 "micro-channel, parallel flow: the huge prospects of energy saving and environmental protection

  "Micro-channel, parallel flow has not been popular in the market as a new member of the air-cooled heat exchanger, but its advantages and characteristics have long attracted industry bursts hubbub. Refrigeration Express reporter understands, "micro-channel, parallel flow" belongs to the latest products for the refrigeration industry, relatively early use in the automotive air conditioning industry, began in the last two years in the development of the refrigeration industry, currently involved in "micro-channel, parallel flow not many "enterprise, Fuyuan, Zhejiang, Hunan three workers is one of the representatives.

  According to Zhejiang Fuyuan Wang, microchannel heat exchanger has a highly efficient heat exchanger efficiency, light weight, pure aluminum design, compact size, and greatly reduce the system cost. In addition, due to the small volume of this product, the average reduction of 30% of refrigerant charge fluence, effective in reducing damage to the environment. Therefore, from the point of view of long-term, this product fit the theme of the "low-carbon", due to its environmental protection, high heat transfer efficiency, the future prospects for development must not small. The microchannel is certainly the direction of future development, body products, materials will be more economical, low-carbon, energy-saving, high efficiency is the focus of our industry. "Hangzhou Shen's side Kazuhiko.

  However, the industry is this still holds a different view. Kuwait Shen total Since this product is used in pure aluminum design, high stability of aluminum as copper, have to be improved in terms of security. Air conditioning and refrigeration market, experts say, the product of the "micro-channel, parallel flow microchannel design brings cooling efficiency increased dramatically also a downside - microchannel prone to clogging. Further defrosting of the "micro-channel, parallel flow" is also a need to solve the problem.

  A new product to market must go through the market continues to baptism, rookie as a two-device industry, micro-channel, parallel flow "will become better and better in terms of products and technology, and ultimately win the market.
