Description

Improved condenser and condensation process thereof

Technical Field

The invention relates to the technical field of condensers, in particular to an improved condenser and a condensation process thereof.

Background

The refrigerating principle of a common refrigerator is that a compressor compresses a working medium from low-temperature low-pressure gas into high-temperature high-pressure gas, the high-temperature high-pressure gas is condensed into medium-temperature high-pressure liquid through a condenser, and the medium-temperature high-pressure liquid becomes low-temperature low-pressure liquid after being throttled by a throttle valve. The low-temperature low-pressure liquid working medium is sent into the evaporator, absorbs heat in the evaporator and evaporates to become low-temperature low-pressure steam, and the low-temperature low-pressure steam is sent into the compressor again, so that the refrigeration cycle is completed.

The condenser works on the principle that the gas passes through a long pipe (usually coiled into a solenoid) to dissipate heat into the surrounding air, and metals such as copper, which have high thermal conductivity and are commonly used for transporting steam, are used. In order to improve the efficiency of the condenser, radiating fins with excellent heat conduction performance are often added on the pipeline, the radiating area is enlarged to accelerate the heat dissipation, and the air convection is accelerated through a fan to take away the heat.

In the working process of the condenser, the heat dissipation load of the tube body at the inlet of the condenser tube is generally much larger than that of other positions, wherein the heat dissipation load at the position is worse as time goes on, and therefore, in order to improve the heat dissipation efficiency of the condenser tube, it is necessary to adopt an alternate condenser tube.
