Abstract

The invention discloses a heat exchanger and a refrigeration device, and relates to the technical field of refrigeration products. The heat exchange efficiency of the heat exchanger can be improved. The heat exchanger comprises a refrigerant pipe. A heat dissipation straight pipe is in contact connection with the outer surface of the refrigerant pipe. The heat dissipation straight pipe is vertically arranged, the upper and lower ends are open, the heat dissipation straight pipe can generate a chimney effect to accelerate convection of air outside the heat dissipation straight pipe and air inside the heat dissipation straight pipe. The heat exchanger can be used for a condenser and an evaporator of the refrigeration device.

Description

technical field [0001] The invention relates to the technical field of refrigeration products, in particular to a heat exchanger and a refrigeration device. Background technique [0002] For refrigeration products, users usually pay more attention to the price, heat transfer effect and noise of refrigeration products. As the key part of refrigeration, the design of heat exchanger will directly affect the above parameters of refrigeration products. [0003] At present, heat exchangers (including condensers and evaporators) of refrigeration products are all developing in the direction of compact structure, low cost and environmental protection. From the perspective of the heat exchange efficiency of heat exchangers, among the commonly used heat exchangers, microchannel heat exchangers are the best, followed by fin heat exchangers, expansion plate heat exchangers, and wire tube heat exchangers. , plate-tube heat exchanger, and finally a bare-tube heat exchanger. The cost is j...
