In order to provide a cooling/heating apparatus for a semiconductor processing liquid being highly resistant to corrosive chemicals and free from elution of harmful impurities, a heat exchanging substrate 3 is formed by heat-depositing a fluorine-contained resin sheet 3B to a processing liquid contact surface of a graphite substrate 3A.

The increase of temperature in heat sensitive devices during heat generating conditions is prevented through the absorption of heat, by providing an organic acid such as formic acid, acetic acid, propanoic acid, butyric acid and the mixtures thereof, in an amount sufficient to effect the required heat absorption. Where the heat generating conditions are generated by a heat generator, separate and distinct from the heat sensitive device, the organic acid is supported in a position between the heat sensitive device and the heat generator. Where the heat sensitive device is itself the heat generator, the organic acid is contacted to the heat sensitive device either directly or indirectly.

The increase of temperature in heat sensitive devices during heat generating conditions is prevented through the absorption of heat, by providing a carbonate salt, such as Lithium Carbonate and its hydrates, Sodium Carbonate and its hydrates, Potassium Carbonate and its hydrates, Magnesium Carbonate and its hydrates, Calcium Carbonate and its hydrates, Beryllium Carbonate and its hydrates, Aluminum Carbonate and its hydrates, and the mixtures thereof, in an amount sufficient to effect the required heat absorption. Where the heat generating conditions are generated by a heat generator, separate and distinct from the heat sensitive device, the carbonate salt is supported in a position between the heat sensitive device and the heat generator. Where the heat sensitive device is itself the heat generator, the carbonate salt is contacted to the heat sensitive device either directly or indirectly.

A pressurized fluid circulating assembly includes a body made of non-metallic, brittle material. At least two apertures formed by internal threads are disposed in the body. First coupling members each include a first externally threaded male portion that can engage the threads of one of the apertures, a second internally threaded female portion and a head with multiple flats. Second coupling members each have an externally threaded male portion that can engage the second threaded portion of one of the first coupling members. A movement-inhibiting member is disposed at a fixed position near at least one flat of each of two of the first coupling members to prevent their rotation. A device may employ a movement-inhibiting member having a size and shape so as to be adapted to be received at a fixed position near at least one flat of each of two of the first coupling members when threaded into engagement with the apertures, thereby preventing rotation of the first coupling members. A method includes rotating to a tightening torque the externally threaded male portions of each of the first coupling members into engagement with the threads of one of the body apertures. The movement-inhibiting member is disposed at a fixed position near at least one flat of each of two of the first coupling members. The externally threaded male portion of each of the second coupling members is threaded into the second internally threaded female portion of one of the first coupling members. Rotation of the first coupling members is prevented by engaging the at least one flat of each of the first coupling members with the movement-inhibiting member.

The present invention relates to an Al alloy brazing sheet for use in vacuum brazing, which is applied to manufacture a heat exchanger having a tank portion and a refrigerant passage respectively formed by bonding press-formed brazing sheets together by means of vacuum brazing. The brazing sheet includes an Al alloy core material having a composition consisting of 0.5 to 2.0 mass % (hereinafter abbreviated simply as %) of Mn, 0.1 to 1.0% of Cu, 0.05 to 0.5% of Mg and 0 to 0.3%. of Ti, with the remainder being Al and inevitable impurities. An Al--Si--Mg alloy brazing filler metal or an alloy brazing filler metal prepared by further adding 0.05 to 1.0% of Sn to the Al--Si--Mg alloy brazing filler metal, is clad on both surfaces of the sheet to a thickness of 5 to 20% the total sheet thickness. An intermediate layer consisting of an Al alloy having a composition consisting of 0.5 to 2.0% of Mn, 0.05 to 0.5% of Mg and 0 to 0.3% of Ti, with the remainder being Al and inevitable impurities, is provided between the core material and the brazing filler metal corresponding to the outside of the tank portion and the refrigerant passage and has a thickness of 30 .mu.m or more, preferably 80 .mu.m or more, and 35% or less of the total sheet thickness. This Al alloy brazing sheet provides excellent outside corrosion resistance for the heat exchanger.

A heat exchanger (10) assembly with a first header (12), a second header (14), a plurality of seamed or folded type heat exchanger tubes (18) extending between the two headers (12, 14), and a plurality of heat exchanger fins (16). Each of the plurality of fins (16) has between 0.01% and 0.9% magnesium to improve the braze between the header (12, 14) and tube joint and the tube seam to inner surface joint (140). Additionally, the headers (12, 14) have a cladded inner surface with between about 0% to about 12.6% silicon to improve the braze at the tube-to-header joint.

An air conditioning system comprising a chamber with a heated air space at a first temperature; a heat sink located in proximity to the chamber, the heat sink being provided with cooled media at a second temperature lower than the first temperature; a plastic heat exchanger located within the chamber with an associated fan for the movement of air within the chamber across the heat exchanger; and a plurality of plastic lines coupling the heat exchanger and the cooled media, the lines including a first line to convey water from the heat exchanger in the chamber to the cooled media and a second line to convey water from the cooled media to the heat exchanger in the chamber with an associated pump to effect the flow of water in a closed loop configuration between the cooled media and the heat exchanger whereby the heated chamber air space will be cooled to a lower temperature from the cooled water from the cooled media while the temperature of the cooled media will be heated to a higher temperature from the heated chamber air space.
摘要:
A heat exchanger, preferably intended for air conditioning in a fan installation, comprises a corrugated plastic element built up of heat exchanger packs. One of the air flows passes laminarly and unbroken in vertical flow paths formed between strips that hold the individual elements apart from each other. The other air flow passes through channels formed in each element. The walls of the element are thin and the thinner the wall thickness the better the efficiency obtained.
摘要:
A heat exchanging device absorbs heat from a heat source, in the form of waste fluid, and exchanges the absorbed heat to an object which benefits from warming. The heat exchanging device is coupled to a first structure, the combination of the heat exchanging device and the first structure forming a passage for the waste fluid to flow. Within the passage, absorption fins absorb heat from the waste fluid. The device is also engaged with a second structure which contains the object which benefits from warming. The heat absorb by the fins and the remaining body of the heat exchanging device is exchanged to the second structure, which in turn exchanges the heat to the object contained within the second structure. The heat exchanging device exchanges the heat from the waste fluid to the object in a simple and cost effective manner.
