Abstract

The invention provides a gravity heat pipe, comprising an upper cover assembly and a lower cover assembly, a fixing plate is installed above the upper cover assembly, a small fixing plate is fixedly installed below the fixing plate, and a rear fixing plate is arranged above the fixing plate A front fixing plate is installed under the fixing plate; a temperature equalizing plate extending from the inner wall of the insulating part to the center of the insulating part is arranged in the heat insulating part, and the temperature equalizing plate includes a first linear wall and a second straight line extending from the inner wall wall, wherein the acute angle formed by the first linear wall and the inner wall is smaller than the acute angle formed by the second linear wall and the inner wall, the first linear wall and the second linear wall extend toward the fluid flow direction, and the first linear wall and the second linear wall are The point of intersection is located at the upper part of the connection between the first linear wall and the inner wall. By increasing the flow area, the invention can satisfy the continuously increasing changes in the volume and pressure of the vapor, and the temperature of the fluid is uniform, so as to achieve further uniform temperature and improve the service life of the product.

Description

technical field [0001] The invention relates to a gravity heat pipe, in particular to a gravity heat pipe provided with a temperature uniform component. Background technique [0002] Heat pipe technology is a heat transfer element called "heat pipe" invented by George Grover of Los Alamos National Laboratory in the United States in 1963. It makes full use of the principle of heat conduction and phase change medium. The rapid heat transfer properties of the heat pipe quickly transfer the heat of the heating object to the heat source, and its thermal conductivity exceeds that of any known metal. [0003] Heat pipe technology was widely used in aerospace, military and other industries before. Since it was introduced into the radiator manufacturing industry, people have changed the traditional radiator design ideas and got rid of the single heat dissipation mode that only relies on high air volume motors to obtain better heat dissipation. The use of heat pipe technology enables...

Problems solved by technology

On the one hand, during the upward process of the fluid in the adiabatic part, it is generally a vapor-liquid two-phase flow mainly in the adiabatic part, so that the fluid in the adiabatic part is a mixture of vapor and liquid. The existence of the vapor-liquid two-phase flow affects the flow of the adiabatic part Heat absorption efficiency

[0004] In the research, it was found that whether it is the heat absorption at the heat-absorbing end or the insulation of the heat-insulating part, the temperature of the fluid at different positions of the heat-insulating part is not uniform, such as the effect of heat insulation The temperature of the good position is high, and the temperature of the position with poor heat insulation effect is low, because the temperature of the fluid in different positions inside the heat insulation part is different, because the temperature difference will cause the temperature in the heat insulation part to be uneven, so that after entering the heat release end, it will also lead to different positions. The heat dissipation of the condensation section is different, especially when multiple heat release ends and corresponding heat utilization components are involved. Because of the uneven heat absorption of the heat utilization components caused by different heat release ends, the heat utilization components are overheated or overcooled, which affects the operation. Influence

In the case of multiple heat-absorbing ends, different heat sources at the heat-absorbing ends lead to different fluid temperatures in different positions of the heat pipe condensing part, resulting in overheating or overcooling of heat utilization components, which affects operation

[0005]Aiming at the above problems, the present invention improves on the basis of the previous invention, and provides a new gravity heat pipe, thereby solving the problem of uneven temperature of the fluid inside the heat pipe
