Description

Technical Field

[0001] This utility model relates to the field of heat exchange device technology, and in particular to a heat exchange core structure and heat exchange device. Background Technology

[0002] Water-cooled heat exchange technology utilizes the high thermal conductivity of liquid media (usually water or coolant) to quickly transfer heat from heat-generating components to the external environment, thereby achieving efficient heat dissipation.

[0003] Two common structures exist for water-cooled heat exchangers in existing refrigeration systems. One type uses bent ordinary copper tubes. The refrigerant medium in this structure exists primarily as a vapor-liquid two-phase medium within the inner diameter of the copper tubes. The heat exchange capacity depends mainly on the surface area. However, due to the limited outer surface area of ​​the copper tubes, a longer pipe is required to achieve the same heat exchange capacity. The heat exchange area increases with pipe length, resulting in a large device size that is unsuitable for micro-air conditioning systems. The other type is a stainless steel plate heat exchanger. This type uses a method of pressing stainless steel plates to create refrigerant flow channels, which are then welded together layer by layer using brazing. Multiple layers increase the risk of leakage, and internal blockage can prevent further operation. For the same heat exchange capacity, stainless steel is heavier and has poorer heat transfer performance. Furthermore, the manufacturing process for some heat exchanger core structures is complex and costly, limiting their application in micro-air conditioning systems.

[0004] There are still no effective solutions to the problems in related technologies, such as poor heat exchange efficiency, multiple layers of refrigerant medium flow channels posing leakage risks, easy blockage of flow channels affecting operation, and complex manufacturing processes.
