Abstract

The utility model belongs to an integral power unit device. A component and a heat exchanger plate are compressed and connected with a plane circular power device and one end of a heat pipe radiator through a screw bolt under the action of a spring pressure plate. Two planes on the other end of the heat exchanger plate are fastened with and connected with the plane of an aluminum section radiating fin which is formed by extrusion through the screw bolt. Compared with the existing radiator, the integral dimension of the integral unit has is reduced form 40 percents to 50 percents, the integral weight is reduced form 50 percents to 60 percents, and the integral heat resistance is reduced from 40 percents to 50 percents.

Description

Integrated power cell

The utility model relates to a kind of power device, and particularly a kind of power device and heat-pipe radiator have become functional unit component integrally formed.

As everyone knows, heat pipe is to fill a kind of heat conducting element made from suitable working medium in vacuum chamber.Its pyroconductivity is several thousand times of copper.Therefore people are generally with solving the power device heat dissipation problem.Current electron electric power industry adopts power model to popularize day by day, and the heat dissipation problem of high power module device has become problem anxious to be solved.The utility model has designed a kind of integrated power cell device for addressing this problem, the contact heat resistance of element knot and radiator and existing module are tied to compare to the contact heat resistance of radiator and have been reduced more than 80% in the unit, and overall dimensions is compared with existing radiator and reduced by 40～50%.

The purpose of this utility model provides the integrated power cell that a kind of power device and heat-pipe radiator are become one.

The utility model adopts following method to realize: integrated power cell is to adopt a end at planar rondure power device and heat-pipe radiator element to be compressed with heat transfer plate under by the effect of bolt at spring bearer plate to be connected, make it have excellent contact, the other end two planes of heat transfer plate are connected by bolted with the aluminium section bar fin plane of extrusion modling, also have excellent contact.

The utility model compared with prior art, overall dimensions is compared with existing radiator and has been reduced by 40～50%, overall weight reduces by 50～60% than existing radiator, overall thermal resistance has reduced by 40～50%.

Concrete structure of the present utility model and embodiment are provided by the following drawings.

Fig. 1 is a general structure schematic diagram of the present utility model.

Fig. 2 is the plan structure schematic diagram of Fig. 1.

Fig. 3 is the heat transfer plate structural representation.

Below in conjunction with accompanying drawing concrete structure of the present utility model and embodiment are done with further instruction.

Embodiment

See shown in the accompanying

drawing

1,2,3: integrated power cell is to adopt two planes at planar rondure power device 1 and aluminium section bar heat transfer plate 2 one ends of extrusion modling element 1 to be compressed with heat transfer plate 2 under by the effect of bolt at spring bearer plate to be connected, make it have excellent contact, the other end two planes of heat transfer plate 2 are connected by bolted with aluminium section bar fin 3 planes of extrusion modling and form integrated power cell, also have excellent contact.

According to the service condition difference, the inwall of aluminium section bar heat transfer plate 2 is lined with heat pipe 4 copper or that other material is made.This integrated unit can use separately, but also plurality of units is used in combination.
