The invention relates to a cooling apparatus having a cooling structure that comprises at least one surface area for introducing heat, and a cooling member that is connected to the cooling structure in a heat-conducting manner, wherein the cooling member is moveable so as to generate an air flow by means of the movement of the cooling member, the air flow supporting heat emission from the cooling member to the environment.

A cooling arrangement with a housing for receiving electronic printed circuit boards or plug-in modules, and with an air-conditioning device which is connected via a coolant-conducting feed line and a return-flow line with at least one electronic component, to be cooled, on the respective printed circuit board or the plug-in module. The feed line is coupled with at least one component feed line assigned to the electronic component. The return-flow line is coupled with at least one component retu...

The present invention is a cooling device, wherein cooling is effected by enclosing a working fluid in a conduit, which is formed by providing a looped tube formed by interconnecting both respective ends of a stack combining a hot heat exchanger with a cold heat exchanger and a stack combining a cooling heat exchanger with a cooling output heat exchanger and by providing at least one or more acoustic wave generators outside or/and inside the looped tube, and then generating a standing wave and t...

The invention relates to a cooling device, which comprises a cooling fan and a heatsink. The heatsink is directly attached to the heating element to absorb its heat and the cooling fan is disposed on top of the heatsink to dissipate the heat. The heatsink includes a central heat dissipation body and a plurality of fins extending from the periphery of the central heat dissipation body. The central heat dissipation body has a fully-sealed hollow chamber filled with a cooling liquid and disposed an...

A cooler cabinet having an opening defining an access to the interior of the cabinet, the rear of the cabinet being the coldest part of the cabinet, the cabinet comprising at least one shelf with spaced apart vertical walls which together define a flow path having an inlet and an outlet, the outlet being at the front of the cabinet so that food containers to be cooled can be retrieved in succession, the flow path being arranged so that containers pass through the rear of the cabinet before they ...

The present invention provides a device for cooling a warm medium comprising: a vessel wherein a bundle of a number of pipes are disposed and wherein coolant medium flows around the pipe bundle; a pipe plate through which the pipes of the bundle debouch into a reservoir for supply of the warm medium; a support plate mounted at a distance from the pipe plate whereby the pipes are supported and wherethrough the pipes extend; and one or more rings which are each mounted between a pipe and the suppo...

A cooling ceiling for interior air conditioning having a pipe system through which cooling air flows is arranged at least in part between the ceiling (1; 101) of a building and corresponding ceiling elements (3; 103) and is secured in the mounted position by a holding member (5; 105) which carries the ceiling elements (3; 103). In the mounted position, the cooling pipe (4; 104) lies against the ceiling elements (3; 103). A joint (10, 10', 10"; 111, 111', 111") arranged between the holding member...

The invention concerns a cooling device for an electrically driven mixer operating in hot liquids. The motor (1) is surrounded by a cooling jacket (5) having inlet (8) and outlet (9) for cooling medium. The jacket (5) is provided with a concentric partition wall (6) which devide the room inside the jacket into two gaps (7) and (8) respectively of different widths.

The cooling of the outer surface of the rod or other solid active element of a solid state laser is improved by causing coolant to travel in a plurality of, preferably streamline, helical flows extending around this surface in contact with it. The respective longitudinal components of a pair of the helical flows preferably extend in opposite directions along the surface to improve the uniformity of cooling.

The roll comprises a rotatable arbor (1) with an annular sleeve (7) shrunk onto it. There are internal passages (25) in the sleeve for the flow of liquid coolant there along. The internal passages are in communication with ducts (19, 21) in the arbor and the liquid coolant passed along the passages from the ducts forms a thermal barrier in the sleeve between the outer periphery and the interface.
