Description
Technical Field
The invention relates to the field of condensers, in particular to a condenser suitable for a self-circulation evaporative cooling system.
Background
The self-circulation evaporative cooling system is in an externally-closed circulation loop, and can realize self-cooling circulation cooling system under the condition of no external power such as a water pump by utilizing the characteristic that a liquid cooling working medium is heated and gasified and then automatically floats upwards and naturally falls after cooling and liquefying. The existing condenser used for self-circulation evaporative cooling has the same structure as a water-cooling radiator, and an S-shaped pipeline with radiating fins is used for cooling working media. Since the working medium to be cooled in the evaporative cooling is gaseous, unlike the liquid working medium of water cooling, a new condenser structure is required to improve the cooling efficiency.
Patent CN 219083806U discloses a single-body type fin condenser, and the condenser used in the present evaporative cooling system is similar to this structure, and uses an S-shaped pipeline structure with radiating fins, and the radiating area of the pipeline is enlarged by using the radiating fins, so that when the gaseous working medium flows through the pipeline, heat is released outwards, and the gaseous working medium is liquefied into a liquid working medium and then flows back into the liquid cooling working medium at the bottom.
1) Because the volume of the cooling working medium can change sharply in the liquid and gaseous phase change process, partial air needs to be stored in the closed cooling circulation system as buffer, so that structural damage caused by excessive pressure change in the system is avoided. The density of the existing cooling working medium is greater than that of air in the gaseous state, so that when the existing S-shaped pipeline is used, part of air is gathered on the upper part of the condenser, the contact area between the cooling working medium steam and the condenser is reduced, and the heat dissipation efficiency of the condenser is affected.
2) When the existing S-shaped pipeline with fins is used for heat dissipation, liquefied cooling working medium cannot flow out of the pipeline in time, and the contact area between cooling working medium steam and a condenser can be reduced, so that the heat dissipation efficiency of the condenser is affected.
Disclosure of Invention

The invention is realized by the following technical scheme: a condenser suitable for a self-circulation evaporative cooling system comprises an upper cavity and a lower cavity which are arranged from top to bottom;
the upper part of the upper cavity is provided with a pressure release valve, and the lower cavity is provided with an air inlet and a liquid outlet;
a plurality of heat dissipation channels are communicated between the upper cavity and the lower cavity, and heat dissipation components are arranged on the heat dissipation channels.
As a further improvement of the technical scheme of the invention, the heat dissipation assembly comprises heat dissipation fins arranged on the heat dissipation channels.
As a further improvement of the technical scheme of the invention, the heat dissipation assembly comprises a water cooling cavity which is arranged on the heat dissipation channel in a coating mode, and the water cooling cavity is provided with a water inlet and a water outlet.
As a further improvement of the technical scheme of the invention, the water inlet is close to the upper cavity at one side of the air inlet, and the water outlet is close to the lower cavity at one side of the liquid outlet.
As a further improvement of the technical scheme of the invention, the pressure relief valve is positioned at the top of the upper cavity.
As a further improvement of the technical scheme of the invention, a gas-liquid separator is arranged in the lower cavity at the gas inlet, the gas-liquid separator comprises an umbrella-shaped top cap and a plurality of struts which are supported and arranged at the edges of the concave surfaces of the top cap, and the lower parts of the struts are connected with the lower cavity arranged at the periphery of the gas inlet.
Compared with the prior art, the condenser suitable for the self-circulation evaporative cooling system has the following advantages:
the air inlet and the liquid outlet of the lower cavity are connected with an evaporative cooling system, gasified cooling working medium enters the condenser from the air inlet, passes through the gas-liquid separator at the air inlet, rises to the heat dissipation channel for cooling, and flows out of the condenser from the liquid outlet after cooling and liquefying. The upper cavity is positioned at the upper part of the condenser and is used for storing air in the system so as to prevent the air in the system from occupying a heat dissipation channel and affecting heat dissipation efficiency. Since the gaseous cooling medium has a density of about several times that of air, air can collect at the top of the condenser during operation. The pressure release valve arranged in the upper cavity can discharge part of air in the upper cavity when the system pressure is too high.
