摘要： This stretch function-added loading sheet is provided with one sheet body and a force crimping unit. The force crimping unit comprises two clamping block plates and one clamping jig, and on one surface of the sheet body, the two clamping block plates are fixed on both sides of a folding centerline on the sheet body. In a state in which the sheet body is folded along the folding centerline such that the two clamping block plates overlap each other with the sheet body on the inside, the clamping jig is fixed to the two clamping block plates so as to clamp the two clamping block plates. The stretch function-added loading sheet has a stretch function with which the sheet body stretches by the clamping jig opening through application of a tensile force perpendicular to the folding centerline to the sheet body, and shrinks when said tensile force is reduced.

摘要： A cooling apparatus includes a refrigerant tank having a surface to which heating devices are attached and containing liquid refrigerant which is boiled and evaporated by heat transferred from the heating devices, and a radiator for radiating the heat of the boiled and vaporized refrigerant. The radiator has an inflow return chamber provided with a small-diameter opening having a diameter smaller than that of the inflow return chamber. The liquid refrigerant of the gas-liquid mixed refrigerant is dammed by the small-diameter opening of the inflow return chamber and the dammed liquid refrigerant is returned through a return passage to the refrigerant tank. Since the liquid refrigerant contained in the gas-liquid mixed refrigerant is suppressed from flowing by means of the small-diameter opening, the gaseous refrigerant can transfer heat directly to the walls of the radiating passages, so that the deterioration of the radiating performance can be prevented.

摘要： A cooling device boiling and condensing refrigerant includes a refrigerant tank having a boiling space in which a part of liquid refrigerant is boiled and vaporized to gas refrigerant by absorbing heat from a heat-generating member, and a radiator having a header through which gas refrigerant from the boiling space flows into plural tubes connected to the header. One end of the header is inserted into the refrigerant tank, and the inserted end portion of the header has a communication port communicating with the boiling space through a gas refrigerant outlet. The communication port has a lower end at the same position as a lower end of the gas refrigerant outlet. Further, the tubes are inserted into the header to have opened ends within the header, and each lower end of the opened ends of the tubes is set at a position higher than the lower end of the communication port and the lower end of the gas refrigerant outlet. Thus, the cooling device prevents liquid refrigerant from flowing into the tubes from the opened ends in the header.

摘要： A cooling apparatus includes a refrigerant tank containing boiling and condensing refrigerant and a radiator for cooling the refrigerant. The radiator is connected to the refrigerant tank on a front surface thereof, and hot objects to be cooled are attached to a heat-receiving surface formed on a rear surface of the refrigerant tank. The refrigerant is circulated in the apparatus so that the refrigerant is vaporized in the refrigerant tank and condensed in the radiator. The radiator is connected to the refrigerant tank by inserting a pair of header tanks thereof into the refrigerant tank. The insertion length is controlled to obtain good heat conductivity between the radiator and the refrigerant tank and to avoid deformation of a radiator fin contacting the refrigerant tank. Holes for mounting a substrate carrying the hot objects may be made on enlarged portions of a cover plate closing the refrigerant tank. The heat-receiving surface may be elevated from the rear surface of the refrigerant tank to avoid interference between other components mounted on the substrate and the rear surface of the refrigerant tank.

摘要： A cooling device for cooling a heat radiation member disposed in a sealed space includes a heat exchanger in which high-temperature air within the sealed space exchanges heat with low-temperature air outside the sealed space, and first and second centrifugal fans for blowing high-temperature air and low-temperature air into the heat exchanger, respectively. Each of the first and second centrifugal fans is disposed in an upstream side space of the heat exchanger at a side position shifted from center so that a large air-blowing space can be provided within the upstream side space. Thus, high-temperature air and low-temperature air blown by the first and second centrifugal fans can be uniformly introduced into the heat exchanger, respectively.

摘要： A cooling apparatus for cooling a heating body such as a CPU by boiling and condensing refrigerant has a tank having a heating body mounting portion on which the CPU is mounted; a porous metallic sintered body arranged in the tank; and refrigerant contained in the tank. The tank has a pair of faced walls including a heat-receiving wall and a radiation wall. The porous metallic sintered body is arranged along the heat-receiving wall, and transports the refrigerant collected at the bottom of the tank to an adjacent portion of the heating body mounting portion by using a capillary action. Since the refrigerant is boiled at such a wide adjacent portion, a superheat degree of the heating body mounting portion can decrease. Furthermore, since the refrigerant collected at the bottom of the tank is transported to the adjacent portion by the capillary action, an area of the radiation wall soaked in the refrigerant becomes small. As a result, a condensation area for condensing the vapor refrigerant becomes large, and then the supercool degree of the radiation wall can decrease. In this way, a cooling capacity of the cooling apparatus can increase.
摘要翻译： 通过沸腾冷凝制冷剂来冷却诸如CPU的加热体的冷却装置具有：罐，其具有安装有CPU的加热体安装部; 布置在罐中的多孔金属烧结体; 以及储存在容器内的制冷剂。 储罐有一对面墙，包括一个受热壁和一个辐射墙。 多孔金属烧结体沿着受热壁配置，通过毛细管作用将收集在罐底部的制冷剂输送到加热体安装部的相邻部分。 由于制冷剂在这样宽的相邻部分被煮沸，所以加热体安装部分的过热度可能降低。 此外，由于通过毛细作用将收集在罐底部的制冷剂输送到相邻部分，所以在制冷剂中浸泡的辐射壁的面积变小。 结果，用于冷凝蒸汽制冷剂的冷凝区域变大，然后辐射壁的过冷度降低。 以这种方式，冷却装置的冷却能力可以增加。

Within the radiation tube is disposed corrugated inner fins, and an upper space, refrigerant passages through for guiding the refrigerant from the refrigerant tank into the upper space, and thin holes in which a liquid pooling part for returning the refrigerant from the upper space into the refrigerant tank is formed are dividingly formed respectively.
