Heat pipe

Abstract

Present invention relates to computer fittings technology field, in particular referring to inner thermal pipe of computer radiator. Said thermal pipe has axial groove in inner wall and tubular metal mesh grid, said metal mesh grid partial sintering together with copper tube inner wall. Said invention enhances capillarity and improves performance when thermal pipe cooling end being lower than vaporization end.

Description

Technical field: [0001] The invention relates to the technical field of computer accessories, in particular to a heat pipe inside a computer radiator. Background technique: [0002] The calculation speed of the current electronic product chips is getting faster and faster, so the radiators used are gradually unable to meet the demand. In order to improve the heat dissipation rate of the metal sheet of the radiator, many radiators are currently equipped with heat pipes to improve heat conduction rate. [0003] As shown in accompanying drawing 1, the principle of the heat pipe is: a copper tube 01 sealed at both ends has a layer of medium (wick) that enables the liquid to transport the liquid by capillary action. When the liquid at the heating end is vaporized, along the From the central space to the cooling end, it is cooled to liquid again, and then returns to the heating end along the conveying medium along the inner edge, so that the purpose of rapid heat transfer can be ...

Problems solved by technology

[0015] 1. Putting the braided mesh into the copper pipe is a direct insertion method. It cannot be guaranteed that the braided mesh at each position can be close to the inner wall of the copper pipe; the performance of each heat pipe is different, because if the braided mesh cannot be attached to the copper pipe The inner wall cannot play the role of auxiliary axial grooves to enhance the capillary phenomenon, so there must be another form to make the braided mesh close to the inner wall of the copper tube

[0016] 2. The wall thickness of the axial grooved heat pipe itself is thicker than that of the simple braided mesh pipe. If the braided mesh is added, the internal space is limited, not to mention the current requirements of electronic products to be thin and short; the diameter of the heat pipe is only 4 ~ 6mm (millimeters), if the braided mesh cannot cling to the inner wall of the copper pipe, but is deformed due to stress and invades the internal hollow space, it will not only fail to play the role of auxiliary axial grooves to improve capillary phenomenon, but will also hinder steam Run to the condensing end, not to mention that the heat pipe often has to be bent and flattened, which may deform the braided mesh, and cannot be close to the inner wall of the copper pipe, occupying the hollow space inside
