      In recent years, the low-end products of the international heat exchanger industry continue to shift to Asian countries, and China is one of the important markets.

      Developed countries in Europe and America are now paying more attention to the field of high-end plate heat exchangers, and have gradually withdrawn from the shell-and-tube heat exchangers for pressure vessels. The production focus of the world's shell-and-tube heat exchangers has gradually shifted to Japan, Korea, Asian countries such as India and China. However, the competitiveness of various plate heat exchangers is gradually increasing worldwide. As far as the development prospects are concerned, although the shell-and-tube heat exchangers still dominate, the prospects of plate heat exchangers are promising.

      China's industrial heat exchanger industry has grown steadily. China's 100 million US dollars of GDP consumes far more energy than developed countries, and the task of energy conservation and consumption reduction in the industrial sector is urgent and arduous. At present, China's industrial cooling water consumption accounts for about 80% of the total industrial water consumption, and the water intake accounts for 30% to 40% of the total industrial water withdrawal. The heat exchanger equipment is a large industrial energy-consuming and water-consuming household. According to statistics, the energy consumption of heat exchanger equipment accounts for 13%-15% of industrial energy. In order to improve social efficiency, China has recently introduced policies such as resource conservation and clean production, which have greatly increased the application requirements of high-efficiency, water-saving, energy-saving and environmentally-friendly cooling (condensation) equipment in the industrial field. It also requires technical improvements in heat exchangers.

      In the field of heat exchangers, there are still room for improvement in the traditionally used water-cooling, air-cooling and evaporative cooling methods. The composite cooler has many advantages that make it promising.

      The composite cooling (condensation) method can perform combined heat transfer cooling using basic cooling forms such as air-cooling, evaporating, and water-cooling, and obtain optimal cooling (condensation) effect with environmental changes, while reducing resource consumption such as water and electricity. For example, the high-efficiency composite cooler manufactured by Longhua Heat Transfer Co., Ltd. is superior to traditional water-cooling equipment in all aspects, and has the incomparable advantages of traditional water-cooling equipment. It is expected to be low-cost and gradually replace traditional water-cooling equipment.
