Abstract
The utility model relates to a radiator for an electronic device, mainly comprising an aluminum plate provided with a plurality of cooling fins and a heat transmission copper plate which is arranged on and is in surface contact with the plane of the aluminum plate. By using the favorable heat transmission performance of the copper plate, heat generated by the electronic device during work is transmitted and dispersed in time, and thus the heat dissipation rate at unit area is increased. The influence of accumulated heat on the performance of the electronic device is avoided, and simultaneously the current-carrying capacity of the electronic device is enhanced.
Description
The utility model relates to a kind of heat abstractor of electronic device.What be particularly related to is a kind of contact heat abstractor.
The contact heat abstractor of existing electronic device is the aluminum plate that an one side has some heat-dissipating fins, be installed in by the high-power electronic device that will easily generate heat on the plane of this aluminium sheet, utilize aluminium sheet and be distributed in the heat that produces when heat-dissipating fin on the aluminium sheet another side distributes electronic device work.Development along with power electronic technology, the electric current that device is required to pass through day by day increases, and its volume requires little as far as possible, this volume-diminished, the trend that electric current increases makes that the heating phenomenon of electronic device is even more serious, caloric value is also more concentrated, and the limited heat-dissipating aluminium plate of coefficient of heat transfer is difficult to by limited contact surface the caloric value of device in time be distributed at short notice, causes the accumulation of heat and causes the running parameter of device to change even cause the overheated of device to burn.
The purpose of this utility model is in order to overcome the above-mentioned shortcoming and defect of prior art, for electronic device high-power, easy heating provides a kind of radiating efficiency high contact heat abstractor.
The purpose of this utility model is achieved through the following technical solutions: have in existing one side and be provided with one on the plane face of aluminium sheet of some heat-dissipating fins and be the heat transfer copper coin that face contacts with this plane face, electronic device is installed on this heat transfer copper coin, or this heat transfer copper coin is touched mutually with the heating face of electronic device, utilize the fast characteristic of heat conduction of copper coin, the heat that produces when electronic device is worked in time absorbs and passes to band wing aluminium sheet and together distributes, thereby has avoided the influence that the performance of electronic device produced because of the accumulation of heat.
The utility model is simple in structure, making is easy, only on existing aluminium heating panel, set up a copper coin that heat-conductive characteristic is good, the heat dispersion and the rate of heat dissipation of unit are are improved greatly, the influence of not only having avoided the accumulation of heat to cause to device, also widen simultaneously the ampacity of electronic equipment, be particularly suitable for the small-volume large-power electronic device.
Below in conjunction with embodiment and accompanying drawing the utility model is described in further details.But content of the present utility model is not limited in the present embodiment indication.
Fig. 1 is a structural representation of the present utility model
As shown in Figure 1, the utility model is made of aluminium sheet 2 that has heat-dissipating fin 1 and the copper coin 3 that is arranged on the aluminium sheet 2.Common modes such as that the one side of copper coin 3 can adopt is sticking, riveting, bolt connection are the face contact with the plane of aluminium sheet and are connected, another side can be made into the shape that the surface with institute contacting electronic device 4 matches, to increase the contact area between copper coin and the device, the heat that is beneficial to when device worked distributes through the copper coin transmission.The heat radiation that the area of copper coin, thickness can be known institute's contacting electronic equipment requires appropriate design.Under the situation of the service behaviour that does not influence electronic device, still can copper coin be set, in order to this heat is in time passed to walk to distribute at other comparatively serious position of heating of electronic device.
Claims (1)
1, a kind of contact heat abstractor of electronic device has the aluminium sheet of wearing some heat-dissipating fins one by one, it is characterized in that also being provided with on the another side of described aluminium sheet with this aluminium sheet plane being the heat transfer copper coin that face contacts.
