Abstract

The utility model discloses a heat radiation device of an electric unit, which comprises a bottom plate and a cover plate, wherein a heating electronic device is arranged in the bottom plate, heat conductive posts are distributed at one side of the cover plate, fins are distributed at the other side of the cover plate, and the heat conductive posts are in contact with the heating electronic device through a heat conductive lining pad. The heat radiation device uses the soft heat conducting lining pad to connect the heating electronic element and the heat conductive posts. Compared with the direct rigid connection of the heating electronic element and the heat conduction posts, the soft connection has higher fit degree. Compared with a heat radiator of an ordinary electronic unit, the utility model is mainly characterized in that heat radiation posts are added on the cover plate, the mechanical structure is simple, and in addition, the installation is convenient.

Description

A kind of radiating element of electronic unit
Technical field
The utility model belongs to electronic information field, relates to the radiating element of a kind of heat abstractor, particularly a kind of electronic unit.
Background technology
At present, in electronic information field, the heat that heater members distributed in the electronic unit mainly passes to box body by the air ature of coal in the box body, is dispelled the heat by box body again.Because the thermal resistance of air is bigger, the heat-sinking capability of this kind radiating mode is very limited.In the electronic unit of high-power, multicore sheet, this kind radiating mode can't satisfy the heat radiation requirement of electronic equipment, might cause the electronic equipment temperature too high and lost efficacy, even electronic equipment is burnt.
Summary of the invention
Defective or weak point at above-mentioned prior art existence, the present situation of the electronic unit heat radiation difficulty of especially high-power, multicore sheet, the purpose of this utility model is, a kind of radiating element of improved electronic unit is provided, to strengthen the heat-sinking capability of electronic unit, improve the thermal reliability of electronic unit, and also simple in structure, easy for installation, requirement on machining accuracy is low.
In order to realize above-mentioned task, the technical solution that the utility model adopts is as follows:
A kind of radiating element of electronic unit, this radiating element comprises base plate and cover plate, and heating electronic component is installed in the base plate, it is characterized in that, one side of described cover plate is distributed with heating column, and opposite side is distributed with fin, and heating column contacts with heating electronic component by chill bar.
Above-mentioned heating column, fin and cover plate can be made into one.
Above-mentioned heating column can be one or more as required.
Above-mentioned chill bar is selected soft chill bar.
The technique effect that the utility model brings is:
1, connect heat-generating electronic elements and heating column by soft chill bar, directly being rigidly connected of heat-generating electronic elements and heating column relatively, the compatible degree of soft connection is higher;
2, owing to be soft connection, heating column can adopt lower machining accuracy to meet the demands;
3, the cross section of heating column has covered whole heat-generating electronic elements, the maximized heat dissipation channel that enlarged;
4, the radiator main difference part of this radiating element and ordinary electronic unit is to have increased thermal column on the cover plate, and mechanical structure is simple, and easy for installation;
5, the length of heating column and position can not only be fit to the heat radiation requirement of the electronic unit of single heater element according to the height and the set positions of heat-generating electronic elements, also can satisfy the heat radiation requirement of the electronic unit of multiple thermoelectric elements.
Description of drawings
Fig. 1 is the structural representation of radiator structure electronic unit of the present utility model.
Fig. 2 is the cover plate schematic diagram of radiator structure device, and wherein (a) is front view, (b) is end view.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Embodiment
Referring to Fig. 1 and Fig. 2, the radiating element of electronic unit of the present utility model comprises base plate 1 and cover plate 5, heating electronic component 2 is installed in the base plate 1, one side of cover plate 5 is distributed with heating column 4, and opposite side is distributed with fin 6, and heating column 4 contacts with heating electronic component 2 by chill bar 3.
Chill bar 3 is the material soft, that thermal resistance value is lower, also other heat conductivility better material, and heat pipe etc. for example, and also chill bar 3 length can be determined according to the height of heating electronic component 2.If not simultaneously, can changing the length of heating column 4, the height of heating electronic component 2 comes the compatible degree of fit adjustment heating electronic component 2.
Cover plate 5 and heating column 4 and fin 6 on the make can be used as an integral body, and the sectional area of heating column 4 can cover whole heating electronic component 2, the number of heating column 4 can be selected according to actual needs, can be one or more, also can evenly distribute or be provided with according to the arrangement of heating electronic component 2.The heat of heating electronic component 2 is passed to heating column 4 by chill bar 3, conducts to the fin 6 of cover plate 5 outsides by heating column 4, and the heat diffusion that heating electronic component 2 is produced by fin 6 is to external environment condition, thereby reaches the purpose of heat radiation.
The installation aspect, as shown in Figure 1, because heating column 4 and fin 6 and cover plate 5 are as a whole, in design process, when the position of heating column 4 is guaranteed, only need correct install cover plate 5 and base plate 1 combination, can guarantee the heat dissipation channel smoothness of heating column 4 and heating electronic component 2.
