Embodiment Construction

[0024] like figure 2 As shown, the heat pipe sealing structure of the present invention includes a partition 5 , a sealing block 3 , a sealing ring 4 , and a compression nut 6 .

[0025] The heat pipe 1 can be a light pipe, a finned pipe and other structures;

[0026] The sealing surface of the gasket on the partition is set above the hole of the partition and sinks into the partition, which is convenient for the sealing ring 4 to limit and protect the sealing surface;

[0027] The sealing block 3 is welded with the heat pipe 1, and is installed from the top to the partition hole along with the heat pipe 1. The upper part is provided with a sealing surface to compress the sealing ring 4, and the lower part is provided with an external thread to cooperate with the internal thread of the compression nut 6;

[0028] The compression nut 6 is installed below the partition hole, and the purpose of compressing the sealing ring is achieved by rotating the compression nut 6 .

Abstract

The invention provides a heat pipe sealing structure. The heat pipe sealing structure comprises an isolation plate and a sealing block. An isolation plate hole is formed in the insulation plate. A heat pipe penetrates through the isolation plate hole. A cold flow section and a heat flow section of the heat pipe are isolated by the isolation plate. The sealing block is welded to the heat pipe and penetrates into the isolation plate hole together with the heat pipe. A sealing plate is arranged on the upper portion of the sealing block. An external thread section is arranged on the lower portionof the sealing block and rotataly connected with a pressing nut. The sealing plate of the sealing block can be tightly pressed on the upper surface of the isolation plate by rotating the pressing nut.The heat pipe sealing structure is simple in structure, convenient to machine and good in sealing performance.

Description

technical field [0001] The invention belongs to the field of heat pipe heat exchangers, in particular to a sealing structure for a partition between a cold-side medium and a hot-side medium of a heat pipe heat exchanger. Background technique [0002] The heat pipe is a heat transfer element with high heat transfer performance. It transfers heat through the phase change latent heat of the working medium in the closed vacuum tube shell. It has the characteristics of large heat transfer capacity and high heat transfer efficiency. [0003] Typical gravity heat pipes such as figure 1 shown. Heat pipe heat exchangers are generally composed of multiple heat pipes, which have many advantages such as high heat transfer efficiency, small resistance loss, compact structure, reliable operation and low maintenance costs. They are widely used in space technology, electronics, metallurgy, power, petroleum, chemical industry, etc. Various industries have been widely used. [0004] The he...
