An evaporator has a header tank including a header forming plate with outward bulging portions, a tube connecting plate, and an intermediate plate. Tube insertion holes are formed in the tube connecting plate. Communication holes formed in the intermediate plate cause the tube insertion holes to communicate with the interior of the corresponding outward bulging portion therethrough. At least one of the outward bulging portions allows a refrigerant to flow therethrough longitudinally. All the com...

The present invention provides a heat pump including: a compressor; a radiator; a first throttling device having a variable opening; an expander; a second throttling device having a variable opening; an evaporator; piping that connects the compressor, the radiator, the first throttling device, the expander, the second throttling device, and the evaporator so that refrigerant circulates thorough the elements in that order; and a control device for controlling the opening of the first throttling d...

A heat sink for dissipating heat from an electronic component comprises a heat spreader and a plurality of first fins and second fins provided thereon. The first and second fins are parallel to each other and arranged in alternating order so as to define a plurality of air passages. The first and second fins are so arranged that thinner air passages and denser fin distribution in the middle along the extension direction of the air passages and wider air passages and lower fin distribution densit...

A known heat exchanger has a lower rate of blocking the movement of moisture through the joint as compared to a joint bonded with a moisture impermeable adhesive because the corrugated and flat substrates are bonded with thermoplastic fibers by performing heating and pressurizing treatments, but has insufficient moisture permeability because both the flat substrate, which is a partition, and the corrugated substrate, which is a space retaining plate, have a poor moisture permeability.In a heat e...

An apparatus for the heating of a viscous fluid contained in a heat generating chamber by a rotatable unit having a fluid shearing surface formed on a face thereof, the unit by shearing of the viscous fluid on that face induces the heating of said viscous fluid and where an external heat extracting surface is provided for this heat to be removed by a further fluid in contact with that surface. The two dissimilar fluids are kept apart by at least the housing acting as a fluid partition. The unit ...

According to some embodiments, an arrangement is provided for cooling a heat-generating device, including a memory module (e.g., a small outline dual inline memory module), in a system such as a laptop computer. The arrangement includes a heat spreader having a first section including at least one thermally conductive coupling member to thermally engage surfaces of electronic components on the heat-generating device and a second section including at least one spring member to cause pressurized e...

The invention discloses systems for mounting heat shields onto a spacecraft. It shows a number of ways to attach heat shield tiles in a way that allows for and accommodates the thermal expansion and contraction of the tiles without overstressing them and without loosing them due to delamination of adhesives. Shown also are various fasteners, which are flexible in several directions and which should preferably be oriented to provide the least resistance to the expected deformations of the tiles.

The heat blanket (10) comprises an operative unit (20) and a control/power supply unit (40) which can be electrically connected on one side to the power mains and on the other side to the operative unit (20). The operative unit (20) comprises a foldable sheet (21) and a linear heating element (22) distributed in the sheet (21), with a first and second conductor extending one along the other, separated by a first electrically insulating material and enclosed by a second electrically insulating ma...

A heat exchanger having at least one heat exchanger block (1) and an insulating vessel which surrounds the heat exchanger, is provided with plates and joints for securing the heat exchanger block (1) suspended in the insulation vessel. In addition, the heat exchanger block (1) is arranged movably in the insulation vessel.

An improved heat exchanger which resists fouling of the heat exchange surface by minimizing the temperature difference between the heat exchanger surface and the fluid stream in contact with the heat exchange surface. In one embodiment, a heat exchanger comprises an outer shell, the outer shell comprising a first inlet operable to pass a first fluid stream, an inner shell at least partially disposed within the outer shell, the inner shell comprising a second inlet and an outlet operable to pass ...
