Integral heat pipe heat exchanger

Abstract

The invention relates to an integral heat pipe heat exchanger, comprising an outer shell, a heat pipe heat exchanger device contained in the outer shell and a separator fixedly connected with the outer shell. The heat pipe heat exchanger device comprises an evaporation end and a condensation end. The integral heat pipe heat exchanger is divided into an inner circulation heat exchange system and an outer circulation heat exchange system by the separator and the outer shell. The heat pipe heat exchanger device comprises a connection part which extends along the horizontal direction by leaning a certain angle. The connection part is connected with the condensation end and the evaporation end, and the separator penetrates through the connection part so as to divide the connection part into a first connection part and a second connection part. The first connection part and the evaporation end are together located in the inner circulation heat exchange system; and the second connection part and the condensation end are together located in the outer circulation heat exchange system. The integral heat pipe heat exchanger provided by the invention has the advantages of simple structure, high heat transmission efficiency, small fluid resistant loss and large power-heat ratio.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a heat pipe heat exchanger, and belongs to the technical field of refrigeration equipment. Background technique [0002] In industries such as electric power, communication or electricity, it is widely used in control cabinets. In order to prevent moisture, dust or harmful gas from entering the cabinet, the cabinet is usually closed to the outside. During operation, due to the heat emitted by the components in the cabinet or the outdoor sunlight, the temperature in the cabinet will continue to rise. If the heat is not dissipated in time, the normal operation of the components in the cabinet will be affected. Therefore, the control cabinets used in these industries need to be equipped with special heat exchangers to dissipate heat from the air in the cabinets. [0003] Among the current heat exchangers, there are plate-fin heat exchangers, cross-flow plate heat exchangers, and heat pipe heat...

AI Technical Summary

Problems solved by technology

The production process of plate-fin heat exchanger is complex, with many consumables, heavy weight, high production cost and high price

The cross-flow plate heat exchanger has the advantages of light weight, small size, simple production process, and low production cost, but it has the loss of temperature gradient, and its heat exchange efficiency is still limited, and it needs a certain temperature difference between the two sides of the heat exchange. conditions to work properly

If the outdoor temperature is as high as 45 degrees Celsius in summer, and the temperature in the control cabinet is 50 degrees Celsius, the cross-flow plate heat exchanger will not work properly.
