Thermosyphon heat dissipation device

Abstract

The invention provides a thermosyphon heat dissipation device. A first condensing unit and a second condensing unit are arranged, a first right flow collecting cavity and a first left flow collectingcavity of the first condensing unit and a second left flow collecting cavity and a second right flow collecting cavity of the second condensing unit are perpendicular to and fixedly arranged close toan evaporator, therefore, the space occupation of the thermosyphon heat dissipation device in the vertical direction is reduced; a first steam pipe communicates with the first right flow collecting cavity of the first condensing unit and a right steam pipe connecting hole formed in the evaporator, and a second steam pipe communicates with the second left flow collecting cavity of the second condensing unit and a left steam pipe connecting hole formed in the evaporator; and compared with the mode that only one flow collecting pipe used for collecting steam is arranged on one side of the evaporator, the technical scheme can reduce a stroke difference between the steam from the left side area and the steam in the right side area of a sealed containing cavity of the evaporator to the collecting cavities, and then the temperature difference between the left side and the right side of the evaporator is reduced, and the temperatures of the left and right sides of the bottom of the evaporatorare relatively uniform.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of electronic or electric equipment, in particular to a thermosiphon heat dissipation device. Background technique [0002] The thermosiphon heat dissipation device is composed of a condenser, an evaporator, a steam pipe and a liquid pipe, etc. The evaporator is filled with a working fluid, and the condenser is usually composed of two collecting pipes on both sides and multiple pipes connecting the two liquid collecting pipes. The condensing tube is formed. The evaporator absorbs the heat from the heat source and the internal working medium heats up. The working medium heats up to generate steam. The steam enters the condenser through the steam tube to condense into a liquid with a lower temperature, and then flows back to the evaporator through the liquid tube, thereby realizing The heat dissipation effect on the heat source. [0003] In related schemes, refer to figure 1 , the condens...

AI Technical Summary

Problems solved by technology

The steam pipe layout should be as short as possible to reduce the steam flow stroke, thereby reducing the steam flow resistance. In this arrangement, the steam pipe can only be connected to the side of the evaporator close to the header pipe used to collect steam. , then the steam on the side of the evaporator away from the header used to collect steam will have to flow a longer distance to reach the header, which will cause a large difference in heat absorption capacity between the left and right sides of the evaporator
