Description
Technical field
The present invention relates to a kind of power supply, particularly a kind of Switching Power Supply that is used for computing machine.
Background technology
Power circuit for computer comprises various electron device, and switching tube wherein, commutator tube constant power device must be installed in could operate as normal on the heating radiator.
The active computer power supply adopts T-shape or inverted "L" shaped heating radiator usually, it has not finned upstanding portion, can be installed on the circuit board as commonplace components is upright, can not account for too big board area, heat radiation is main to have a fin part by what stretch out from the upstanding portion top, horizontal; This is a kind of mode with heating radiator adaptive circuit plate in fact, the shape of heating radiator and size are subjected to the restriction of circuit board and power supply inner space, area of dissipation is generally limited, must strengthen heat-sinking capability with other method again, and wherein modal solution is the active heat removal mode that fan is arranged.
Fig. 1 is the existing known inner structure synoptic diagram that the fan computer power supply is arranged.As shown in Figure 1, it mainly is that circuit board 10a is provided with various electron device 11a, the upstanding portion 131a of the body of power device 12a and heating radiator 13a is fixed together, stand on the circuit board 10a, because the area of dissipation of heating radiator 13a is limited, must increase fan 30a to strengthen heat-sinking capability.Circuit board 10a and fan 30a are installed among the housing 20a, and forming has fan computer power supply 1a.
Usually, its heat-sinking capability of heating radiator that has increased fan is equivalent to original 4～10 times, so the application scenario that this computer power supply that fan arranged can satisfy various power demands.Yet, owing to increased fan, brought mechanical noise again, the noise of power supply fan sometimes or even the main source of computing machine noise, simultaneously, the not high reliability of this power supply that yet caused of the reliability of fan is not high.Problem for solution has fan power supply to exist has produced a kind of computer power supply that does not have the passive heat radiation of fan.
Fig. 2 is the inner structure synoptic diagram of existing known common no fan computer power supply.As shown in Figure 2, it mainly is that circuit board 10b is provided with various electron device 11b, and the upstanding portion 131b of the body of power device 12b and heating radiator 13b is fixed together, and stands on the circuit board 10b.For making power device 12b operate as normal, must stretch out suitable area of dissipation to horizontal direction at the top of the upstanding portion 131b of heating radiator 13b.Because the shape of heating radiator 13b and size are subjected to the electron device 11b on the circuit board 10b and the restriction of power supply inner space, and the upstanding portion 131b that is fixed on the circuit board 10b also is difficult to prop up reliably excessive entire radiator, and the structure in the historical facts or anecdotes border is more complicated than among the figure usually.Circuit board 10b is installed among the housing 20b, forms common no fan computer power supply 1b.
In further putting into practice, produced the idea that fin is set at the outer wall of housing naturally for increasing area of dissipation, problem is how efficiently heat to be guided on the housing of fin.In existing scheme, have with heat pipe heat internally heating radiator guide to the housing of fin, have in Inner heat sink and have and install the silica gel pad between the housing of fin additional and conduct heat, but can't break away from traditional approach all the time with heating radiator adaptive circuit plate, huge housing just has a fin part as the T-shape heating radiator, the efficient of conducting heat to housing and fin from power device is not high to be the bottleneck that traditional approach is difficult to break through, and the housing heat radiation can not brought into play due advantage.
Therefore, it is big that the power of existing no fan computer power supply is difficult to do if any fan, for satisfying the application scenario of high-power demand, the spare fans scheme that only just starts powerful the time has appearred again in the result, perhaps simply whole power supply is put into outside the cabinet, makes the no fan computer power supply of external.
In general, there is following shortcoming in the traditional computer power supply:
The heat that-power device gives out must could arrive the fin of main thermolysis through quite long conducting path, and the efficient of the heat transfer not efficient of high feasible heat radiation is not high yet;
-power device is in power shell inside, and heating radiator is among the same environment also in power shell inside, causes the power supply temperature inside higher, and being unfavorable for dispelling the heat also is unfavorable for the work of circuit;
-must adopt extremely complicated structure to match with the housing that fin is arranged, radiating effect is not good simultaneously, and the cost height is not easy to produce and safeguard.
Summary of the invention
Purpose of the present invention, be to overcome the shortcoming of active computer power supply, a kind of simple in structure, good no fan computer power supply of heat radiation is provided, its mentality of designing is that power device and related device are separated from power circuit, composition one is assemblied in the sub-circuit board of upper enclosure inner wall, wherein, power device is arranged in the periphery of sub-circuit board, its pin is connected on the circuit of sub-circuit board, its body is fixed on the inwall of upper shell, thereby the fin of the heat of power device generation by the upper shell outer wall promptly left; This is a kind of mode with circuit board adaptation heating radiator in fact, and the shape of heating radiator and size are not subjected to the restriction of circuit board and power supply inner space fully, and power device and radiating fin lay respectively at the inside and outside wall of housing, give full play of the advantage of housing heat radiation.
The technical scheme that realizes the object of the invention is:
