A kind of electronic devices and components circuit board
The utility model relates to a kind of electronic devices and components circuit board.
The existing electronic devices and components circuit board that need lower the temperature to the electronic devices and components in the work generally is by a middle thick copper coin that is processed with cooling water channel, and several electronic devices and components are fixed on the thick copper coin according to arranging in proper order.During work, in cooling water channel, feed cooling fluid,, prevent that electronic devices and components from high temperature damaging so that cool off, take away the heat that is produced when electronic devices and components are worked.The shortcoming of this kind electronic devices and components circuit board is the manufacturing cost height, and the processing difficulties of water channel is not easy to be provided with according to the actual needs the water channel of processing special trend in thick copper coin.
Summary of the invention:
Goal of the invention of the present utility model is to provide the electronic devices and components circuit board of a kind of low cost of manufacture, handling ease.
The coil pipe that abuts against the heat-conducting plate surface that the utility model is achieved in that by heat-conducting plate, be fixed on several electronic devices and components on the heat-conducting plate, be arranged on below the heat-conducting plate constitutes, and the both sides below the coil pipe are welded on heat-conducting plate by Heat Conduction Material.Heat Conduction Material is copper or tin.Because adopt the mode of welding coil pipe on heat-conducting plate that the heat that electronic devices and components sent in the work is drained, and the setting of coil pipe and special trend are easy to process, and, coil pipe is set on heat-conducting plate, cost is low.
Here, in order to improve radiating effect, the face that coil pipe is connected with heat-conducting plate is the plane, like this, just can guarantee effectively that coil pipe has enough areas to contact with heat-conducting plate, guarantees the effect of heat radiation.
Compared with the prior art the utility model has advantage low cost of manufacture, handling ease, good heat dissipation effect.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a back of the present utility model view.
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in the figure, the utility model by copper heat-conducting plate 1, be fixed on several electronic devices and components 2 (as resistance) on the heat-conducting plate 1, the bronze pan tube that abuts against heat-conducting plate 1 surface 3 that is arranged on below the heat-conducting plate 1 constitutes, the face that coil pipe is connected with heat-conducting plate is that the plane is (with the following pressing of coil pipe, like this, the following plane that just forms of coil pipe).Both sides below the coil pipe 3 are fixed together with heat-conducting plate 1 by brazing or soldering 4.
