Abstract
The utility model relates to a circuit board radiating device. This circuit board radiating device includes heat conduction material, fin, fan (about each one) and temperature control system, and wherein temperature control system all fixes on the fin with the fan, when circuit board temperature be higher than the institute during to set the temperature value, the fan carry out the forced air cooling and operate controlled to play thermolysis with higher speed to the circuit board, when circuit board temperature was less than the to set the temperature of institute value, the fan will not carry out any work, and the fin dispels the heat by oneself.
Description
Technical field
The utility model relates to a kind of circuit board, particularly relates to a kind of circuit board used the more serious circuit of the heating such as digital circuit, power amplifier.
Background technology
At present, most circuit all adopts radiator to dispel the heat to it, and the radiator of commercial type not only volume is comparatively large and do not have temperature acquisition system, simultaneously, the circuit adopting radiator to carry out dispelling the heat has two shortcomings, the first, causes circuit board to be powered to it.The second, can not carry out intelligent heat dissipation according to the temperature of circuit board, when namely circuit board temperature is higher or lower than certain designated value, heat radiation speed homogeneous phase is same.Therefore.This kind of employing radiator not only adds the volume of circuit board to the method that circuit board dispels the heat, thus adds the cost of product, wastes electric energy again simultaneously, and then increase the power supply burden of system, if things go on like this, the theory of low-carbon environment-friendly will be run counter to, to environment.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of circuit board radiating device, and the volume that can reduce circuit board reduces its cost, effectively can utilize electric energy again simultaneously, thus the combination property of circuit board is got a promotion.
The utility model solves the technical scheme that above technical problem adopts: comprise Heat Conduction Material, fin, fan (each one of left and right) and temperature control system, Heat Conduction Material is directly placed with on circuit boards by buckle, fin is directly crimped on Heat Conduction Material by buckle, Heat Conduction Material is provided with thermistor, fin is fixed with two fans in left and right and temperature control system.
First, by the good Heat Conduction Material of insulation, heat conduction, permeance by circuit board distribute more than 90% heat be directed at fin, the magnetic field that circuit board gives off is closely coupled on Heat Conduction Material simultaneously, thus decreases the external radiated interference of circuit board.Secondly, detected the temperature of fin by temperature control system, when temperature exceedes alarm temperature, two, left and right fan fixing on fin carries out work by controlled, wind-cooling heat dissipating sheet, and accelerating circuit plate dispels the heat.Otherwise when temperature is lower than alarm temperature, fan will not carry out any work, fin auto-radiating.
The utility model has the advantages that: the first, the dependability of circuit board can be improved.The second, circuit board volume can be reduced and reduce its cost.3rd, effectively can utilize electric energy.4th, low-carbon environment-friendly, protection of the environment.

Fig. 2 is the thermistor schematic diagram of Heat Conduction Material.
Fig. 3 is the fin schematic diagram being fixed with fan, temperature control system.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, the utility model is a kind of circuit board radiating device, comprise Heat Conduction Material 2, fin 3, fan (each one of left and right) and temperature control system, Heat Conduction Material is directly placed with on the circuit card 1 by buckle, fin 3 is directly crimped on Heat Conduction Material 2 by buckle, Heat Conduction Material 2 is provided with thermistor 4, fin 3 is fixed with two fans in left and right and temperature control system.
During this use is novel, Heat Conduction Material is directly placed with on circuit boards, and the fin being fixed with fan and temperature control system is then directly crimped on Heat Conduction Material.
First, after circuit board is started working, thermistor on Heat Conduction Material (shown in nine small circles in Fig. 1) temperature of circuit board will be sensed and the heat conduction of circuit board is distributed more than 90% to fin, the magnetic field that circuit board gives off is closely coupled on Heat Conduction Material simultaneously, thus decreases the external radiated interference of circuit board.Therefore, fin (as shown in Figure 2) will sense the temperature of circuit board.
Second, after fin receives the temperature of conducting from Heat Conduction Material, fixing temperature control system (as shown in Figure 2) on a heat sink will judge this temperature, if when this temperature is higher than alarm temperature, temperature control system carries out work by being driven fixing two, left and right fan (as shown in Figure 2) on a heat sink by power MOS pipe, fan carries out air-cooled work by controlled, thus the heat radiation of accelerating circuit plate.Otherwise if when temperature is lower than alarm temperature, temperature control system will not carry out any work, fin auto-radiating.
Circuit board, Heat Conduction Material and the fin mounting means being fixed with fan and temperature control system are that Heat Conduction Material is directly placed with on circuit boards by buckle.The fin being fixed with temperature control system and fan is directly crimped on Heat Conduction Material by buckle.
