摘要:
An apparatus to regulate and control the temperature of an axle assembly for a vehicle. A heat pipe is inserted though the axle housing cover, the heat pipe travels the length of the cover. Near the lower region of the carrier and beneath the lubricating fluid level, the heat pipe bends to continue in the horizontal direction. Disposed about the terminal end of the heat pipe below the lubricating fluid line are a series of cooling fins. Heat generated within the lubricating fluid that is heated during operation conduit is dissipated via the cooling fins.
摘要:
A cooling system for apparatus powered by electricity, that generates a substantial amount of heat during operation, and the heat must be dissipated to avoid failure of electrical and/or electronic components, such as semiconductor devices and integrated circuits, comprising the electrical apparatus. The cooling system employs water impinged on a heat sink thermally coupled with electrical apparatus, at subatmospheric pressure. The attendant phase change of the water to steam at a reduced temperature due to the subatmospheric pressure improves removal of waste heat to prevent failure of the electrical apparatus.

A cooling system and method, and a cooled electronics assembly are provided employing a thermal spreader having an inner chamber evacuated and partially filled with a liquid. A phase separator is disposed within the thermal spreader to at least partially divide the inner chamber into a boiling section and a condensing section, while allowing vapor and liquid to circulate between the sections. A heat extraction assembly is disposed at least partially within the inner chamber to extract heat therefrom. When the thermal spreader is coupled to a heat generating component with the boiling section disposed adjacent thereto, liquid within the thermal spreader boils in the boiling section, producing vapor which flows upward from the boiling section and causes liquid to flow into the boiling section from the condensing section, thereby providing circulatory flow between the sections and facilitating removal of heat from the heat generating component.
摘要:
A boiling cooler has a heat exchange part in which refrigerant vapor performs heat exchange with cooling water. The refrigerant vapor is produced from liquid refrigerant that is boiled and gasified by heat transferred from a heating element. In this boiling cooler, the refrigerant vapor can be cooled by cooling water having a thermal conductivity larger than that of air.

A bubble cycling heat exchanger is disclosed. A closed fluid loop is in contact with a heat absorbing source through a heat conducting block; the loop has a bubble generator, an expanding area for generating bubbles is installed at loop; the loop is also formed with a guide region from which bubbles is easily separable and a radiator; a heat conducting block of the closed loop is connected to a heat absorbing source; since the overheat of the heat absorbing source will cause the loop to generate bubble; by an unequilibrium formed at the guide region of the loop, the bubbles will separate from the heat absorbing source so that the liquid in the loop flows for transferring heat so that heat is radiated by the fins or other elements of the radiator from the primary element of a computer at the heat absorbing source, the loop operates continuously until a heat equilibrium is achieved.
摘要:
In a reactor (1) which has a bundle of catalyst tubes (2) and in which a heat transfer medium is circulated through the space surrounding the catalyst tubes, with the ring lines (3, 4) at both ends of the reactor with openings (5, 6) through the wall for introduction or removal of a heat transfer medium by means of one or more pumps, where the heat transfer medium is introduced into the lower ring line (4) and is returned via the upper ring line (3) to the pump(s) and the heat transfer medium or a substream of the heat transfer medium may, if desired, be passed over one or more external heat exchangers, and with deflecting plates (7) which alternately leave free an open cross section in the middle of the reactor and at the edge of the reactor, the lower ring line (4) is divided by means of a horizontal dividing wall (8) into two regions between which material can pass via preferably uniformly distributed openings (9) having a regulatable open cross section.

A sealed plate type metallic heat pipe is disclosed having multiple independent through holes which run through the inside of the heat pipe. All of the through holes are connected in fluid communication at each end. A working fluid is disposed in the through holes and a wire or a wire mesh is disposed in at least one of the through holes.
摘要:
A cooling apparatus 1 boiling and condensing refrigerant is constructed to have a stacked construction by stacking a plurality of pressed members 3 and comprises a refrigerant tank portion, a heat exchanging portion and a refrigerant diffusing portion. First openings for passing refrigerant and second openings for passing cooling water are formed in the pressed members 3 used for the heat exchanging portion and the first openings communicate with internal spaces formed in the refrigerant tank portion and the refrigerant diffusing portion. According to the construction, as the cooling apparatus has the stacked construction, tubes and fins that constitute a conventional heat dissipating portion can be eliminated.
摘要:
An elongate tubular refrigerant container 2 has a barrier 5 which partitions its internal space into a heat-generating member side path 2b and a heat radiating path 2c, so that refrigerant vapor evaporated by the heat-generating member 3 is separated from the condensate that circulates after being cooled in the heat radiating section 4. The barrier 5 includes a heat insulating space 5a which does not communicate with the internal space 2a that stores a refrigerant. The refrigerant is prevented from boiling in the heat radiating section side path 2c and the condensate that circulates from the heat radiating section 4 and the refrigerant vapor do not collide violently with each other because the heat of the refrigerant vapor in the heat-generating member side path 2b is prevented from being transferred to the liquid refrigerant in the heat radiating section side path 2c.
