An evaporator includes a container, a wick provided in contact with an inner peripheral surface of said container and formed such that (1) if the number of pores per unit volume is fixed, the diameter of pores is varied, or (2) if the diameters of pores are formed substantially uniformly, the number of pores is varied, a sump having said wick as its inner wall surface and connected to a liquid pipe for supplying a liquid-phase working fluid, and a vapor channel formed in a contact surface of said container with respect to said wick so as to guide a gas-phase working fluid into a vapor pipe connected to an end portion of said container.

An integrated heat dissipation apparatus includes an attachment area, a heat exchange area thermally connected to the attachment area, and an air flow generation area that is integrally formed with the attachment area and the heat exchange area. A thermally conductive member extends between the attachment area and the heat exchange area to facilitate the removal of heat from the attachment area to the heat exchange area. A generated air flow passes through the heat exchange area.
摘要:
The apparatus is a heat pipe with superior heat transfer between the heat pipe and the heat source and heat sink. The heat pipe is held tightly against the heat source by mounting holes which penetrate the structure of the heat pipe but are sealed off from the vapor chamber because they each are located within a sealed structure such as a pillar or the solid layers of the casing surrounding the vapor chamber. Another feature of the heat pipe is the use of more highly heat conductive material for only that part of the wick in the region which contacts the heat source, so that there is superior heat conductivity in that region.

A structure of a super-thin heat plate comprising surrounding bodies having a thin plate shape and supporting body is disclosed. Each supporting body have function of capillarity and is enclosed within the surrounding bodies. The surrounding bodies and the supporting body are connected by a plurality of welding spots, and the edges are properly sealed. The supporting body is distributed uniformly by a whole web structure. Thus, the heat plate wick structure is very stable with a preferred performance of heat transfer and can be finished easily. In mass production, the structure still has a high stability.

A stacked array of low profile heat pipes each with a plurality of micro tubes extended therethrough. The stacked low profile heat pipes are placed into thermal connection with heat producing components. A heat transfer fluid is contained in the micro tubes of the low profile heat pipes and removes the heat from the heat producing components.
摘要:
A parallel-plate heat pipe is disclosed that utilizes a plurality of evaporator regions at locations where heat sources (e.g. semiconductor chips) are to be provided. A plurality of curvilinear capillary grooves are formed on one or both major inner surfaces of the heat pipe to provide an independent flow of a liquid working fluid to the evaporator regions to optimize heat removal from different-size heat sources and to mitigate the possibility of heat-source shadowing. The parallel-plate heat pipe has applications for heat removal from high-density microelectronics and laptop computers.

摘要:
A tabular heat pipe structure with support bodies has a housing, working fluid received in the housing and support bodies. The top and bottom faces of the support bodies are zigzag faces having a plurality of contact points. The support bodies use these contact points to adhere to the housing by means of welding. The tabular heat pipe structure is uniform and intact, has a high rigidity, will not cave in and deform due to back pressure in the heat pipe, and will not let the housing separate from the support bodies because of expansion at high temperatures. Therefore, the tabular heat pipe structure has the advantages like a better heat-conducting characteristic, a smaller contact heat resistance, a simple processing procedure, a quick manufacturing speed, a lower cost, and a simple and stable operation of flat adhesion.
