Abstract
A miniature heat pipe with sintered layer on internal wall is provided, which comprises a pipe body and an exhaust pipe, and one end of the pipe body is crinkled and sealed, and the inner wall of the pipe body is provided with a sintered layer, and an outside diameter extending in radial direction and outward at one end of the exhaust pipe is inserted to an inner hole of the pipe body, the joint of the two pipes is provided with a sealing welding line, and the other end of the exhaust pipe is crinkled and sealed. The miniature heat pipe is filled with heat transmission materials therein. The exhaust pipe is made as standard part according to size, one end of the pipe body is crinkled and sealed, and then powder is loaded and sintering is performed, since the powder is loaded with open mouth, the position of the power loading and the height of the sintered layer are easy to determine. Compared with the prior art, the utility model has the biggest advantage that the miniature heat pipe can be for mass production in factories.
Description
Technical field the utility model relates to a kind of micro heat pipe, and the inwall that specifically a kind of cpu heat uses has the micro heat pipe of sinter layer.
Background technology is well-known; computer microprocessor (CPU) can produce a large amount of heats in operational process; therefore each microprocessor (CPU) is all wanted the heating radiator of configure dedicated; to avoid because of bad too high shutdown of microprocessor (CPU) temperature that cause of dispelling the heat; the micro heat pipe that generally is used for cpu heat is that an end is the pipe of gas outlet for the body other end; body is connected with the tapering transition that is connected to of gas outlet; the pipe two ends are filled with heat-transfer working medium in contracting and sealing, and inboard wall of tube body is attached with the copper mesh as the imbibition core.In order to make the imbibition core better the contact be arranged with the heat pipe inwall, net is made into sinter layer, when having the micro heat pipe of sinter layer, inwall has following problem making like this: if contract envelope exhaust pipe end earlier, the deliquescing of copper powder layer sintering posterior microtubule, the body envelope that can't contract; If the tube sealing body that contracts earlier, the height of sinter layer be difficult for determining, and the gas outlet of the soft attitude hardening of being honored as a queen of contracting behind the sintering, unfavorable to clamp.
The summary of the invention the purpose of this utility model is to overcome weak point of the prior art, connects the micro heat pipe that the inwall that forms has sinter layer and provide a kind of by body and two parts of gas outlet.This inwall has the micro heat pipe of sinter layer, includes body and gas outlet, the body one end envelope that contracts, inboard wall of tube body is provided with sinter layer, external diameter that gas outlet one end radially extends out inserts the body endoporus, and two pipe junctions are provided with the weld seam of sealing, the other end of the gas outlet envelope that contracts.Be filled with heat-transfer working medium in the micro heat pipe pipe.Gas outlet is made standard component by size, the body one end envelope that contracts, and the dress powder sintering, because uncovered dress powder, the position of dress powder and the height of sinter layer are determined easily.Compared with prior art the utility model biggest advantage is: this micro heat pipe can be produced in enormous quantities in batch production.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment is with reference to Fig. 1, and the external diameter that an end of gas outlet 1 radially extends out inserts in body 2 endoporus and forms interference fit, and two pipe connection places are provided with the weld seam 3 of sealing, and inboard wall of tube body is provided with sinter layer 4.
Claims (2)
1. an inwall has the micro heat pipe of sinter layer, includes body and gas outlet, it is characterized in that: the body one end envelope that contracts, inboard wall of tube body is provided with sinter layer, external diameter that gas outlet one end radially extends out inserts the body endoporus, and two pipe connection places are provided with the weld seam of sealing, the other end of the gas outlet envelope that contracts.
