Description

Technical Field

[0001] The utility model relates to the technical field of condensers, in particular to a novel condenser heat exchange structure. Background Art

[0002] The condenser is a component of the refrigeration system and a type of heat exchanger. It can convert gas or steam into liquid and transfer the heat in the tube to the environment near the tube in a very fast way. During the operation of the condenser, the gas passes through the long tube and the heat is dissipated to the surrounding environment. Metals such as copper have strong thermal conductivity and are often used to transport steam. In order to improve the efficiency of the condenser, heat sinks with excellent thermal conductivity are often attached to the pipeline to increase the heat dissipation area to accelerate heat dissipation, and the fan is used to accelerate air convection to take away the heat.

[0003] In the circulation system of the refrigerator, the compressor inhales low-temperature and low-pressure refrigerant vapor from the evaporator, which is adiabatically compressed by the compressor to become high-temperature and high-pressure superheated steam, and then pressed into the condenser for constant pressure cooling, releasing heat to the cooling medium, and then cooled into supercooled liquid refrigerant. The liquid refrigerant is adiabatically throttled by the expansion valve to become a low-pressure liquid refrigerant, which evaporates in the evaporator and absorbs heat from the air-conditioning circulating water, thereby cooling the air-conditioning circulating water to achieve the purpose of refrigeration. The low-pressure refrigerant flowing out is sucked into the compressor, and the cycle works in this way. The single-stage vapor compression refrigeration system is composed of four basic components: a refrigeration compressor, a condenser, a throttle valve, and an evaporator. They are connected in sequence by pipes to form a closed system. The refrigerant circulates continuously in the system, changes state, and exchanges heat with the outside world. Although this heat exchange structure can achieve closed-loop operation, its heat exchange efficiency is relatively low, and it is difficult to control the volume of the condenser within a small range, which correspondingly increases the equipment cost and installation cost.
