Problems solved by technology
How to efficiently combine two different heat exchange structures is one of the difficulties faced. On the other hand, the disadvantage of the tube / plate heat exchanger structure is that the curved deflection part at the end of each pipe is usually located outside the actual heat exchange space , does not participate in heat exchange, resulting in additional costs. At the same time, the cross-section of the pipeline is fully enclosed, and the thermal resistance of the refrigerant when exchanging heat with air is relatively large

The invention discloses a heat exchanger core body, a heat exchanger and a heat exchange method. The heat exchanger comprises a refrigerant / air heat exchanger core body and an air / air heat exchanger core body, and each heat exchange core body is at least provided with a refrigerant channel, a first air channel and a second air channel, and the first air channel and the second air channel are arranged between plates arranged side by side. The refrigerant channel is formed from an extruded profile with a web, a bulkhead, a first flange, a second flange, and a boss. An end of the refrigerant passage is surrounded by an outer plate, and alternating bulkhead portions are shortened to form a first space, thereby forming a one-way serpentine path for passage of refrigerant. The heat exchanger core body, the heat exchanger and the heat exchange method is used for heat exchange of compressed air and has the advantages of being high in heat exchange efficiency and compact in structure.
Description
technical field [0001] The invention relates to a refrigerant / air heat exchanger and a heat exchange method thereof, belonging to the technical field of heat exchange. Background technique [0002] Heat exchangers made of heat exchanger cores can be used in compressed air systems. In many fields, such as food industry, paper industry and medical field, dry compressed air is required, and compressed air is mainly produced by air compressors. As we all know, after the air compressor sucks the air, it compresses the air into high-temperature and high-pressure compressed air. At this time, the compressed air is humid air. Part of the water will be precipitated, so further drying is required. [0003] A common treatment method is to pass the air through a device including an air / air and refrigerant / air heat exchanger, so that the temperature of the compressed air is reduced to below 3-10°C during the heat exchange process with the refrigerant, and condensed water is precipitate...
