The invention relates to devices used for cooling equipment, mainly semiconductor technology, in particular, for removing heat from high-power semiconductor devices when using a refrigerant with a high electrical conductivity coefficient.

A device for cooling heat-generating equipment, such as semiconductor devices, is known, comprising a housing and conductive plates that are insulated with ceramic gaskets from the housing, and liquid 1 is used as the refrigerant.

The disadvantage of this device lies in the low mechanical strength due to the destruction of ceramic pads under axial loads. a) using liquid; sti refrigerant with a high coefficient of consumption;

It is known ycTptjiicTBO to cool the floor of a wiry device containing a heat chamber, partially filled with a light boiling liquid to effect heat transfer by changing the state of heat transfer medium. In the boiling zone of the steam chamber wall, a semiconductor device is placed, and in the condensation zone the chamber has a developed external cross section 2J.

; The disadvantages of this device are:; in the absence of electrical insulation between the gpamodovodnym device and koryiykoM and the need to use in connection with this as the refrigerant air, which leads to significant weight and size characteristics, limiting the use of the device in converters.

According to the main author. St. No. 741021, a device for cooling the heat emission of a young apparatus is known, comprising a housing and a rod inside it and a cup having perforated walls and honestly attached to the refrigerant supply pipe, while the rod is installed perpendicular to the axis of the housing and on the outer edge of the last fold. 3 plates.

The disadvantage of this device lies in the inefficiency of its operation due to the low surface heat transfer.

The purpose of the invention is to intensify heat transfer.

The goal is achieved by the fact that in the device e; 1 the cooling of the power-generating equipment. the core and the cup located inside it, having perforated walls and rigidly attached to the coolant supply nozzle, while the core is installed perpendicular to the body axis and the outer surface of the latter is placed with a hollow core with a capillary structure on the inner surface, with longitudinal ribs on the outer, and filled with light boiling liquid, and one of the walls of the glass is made of a corrugated, envelope ribs.

FIG. 1 shows the device; in fig. 2 shows section A-A in FIG. I.

A device for cooling the heat generating apparatus, comprises a housing 1, a rod 2, a cup 3 with perforated walls 4 attached to the pipe 5 for supplying a refrigerant, conductive plates 6, a pipe 7 for discharging the refrigerant, a ceramic gasket 8.

The rod 2 is made hollow with a capillary structure 9 on the inner surface, the ribs 10 on the outside and is filled with light alloy liquid 11, the wall 2 of the cup is made of a corrugated envelope rib 13, and a heat-generating equipment 14 is installed on one of the plates 6.

The device works as follows.

The refrigerant through pipe 5 enters the housing 1 and, flowing out of the holes of the perforated walls of the glass in the form of jets, takes heat from the apparatus 14 pressed to the wall of the housing 1 through the conductive plastic pipe 6 and the ceramic gasket 8. : boiling of liquid liquids, carried out on the heat transfer walls of the body, and its condensation on the surfaces of the rod washed by the refrigerant. The presence of a capillary-porous structure 9 on the inner surface of the rod 9 allows the device to operate efficiently with any orientation in space. The ribs 10, which is provided with a rod on the outer surface, significantly increase the heat exchange surface.

In order to use a hydraulic penalty, the gap between the perforated wall of the glass and the hollow rod is uneven, the minimum clearance takes place in the perforated zone of the wall located between the ribs of the glass, and it is equal to (3-2) d, where d - diameter of holes in the perforated wall.

The bar with the ribs perceives compressive forces prevents the destruction of the ceramic gasket.

Compared with the known, the proposed device has a thermal resistance of 20-30 ° / o less than it allows to increase the load of the heat generating equipment (semiconductor devices) and, as a result, to reduce the number of devices in the power blocks of the converters
