Abstract
The utility model relates to a radiation stand for power amplifying circuits, which comprises a base plate and a plurality of radiating fins, wherein all of the radiating fins are perpendicularly arranged on the surface of the base plate with a limited distance between two radiating fins, and a circuit board supporting fixing frame is arranged on the back surface of the base plate. The utility model can make the circuit board erect parallelly to the base plate of the radiation stand, so the radiation efficiency and the circuit separation are high; simultaneously, the utility model makes the circuit board have the characteristics of little occupying space and convenient maintenance.
Description
The utility model is a kind of circuit heat radiation rack, and especially a kind of power amplifier heat radiation rack belongs to the improvement technology of power amplifier heat radiation rack.
Power amplifier in power amplifier heat radiation in the market commonly vertically is provided with an incorporate heat radiation rack on monoblock power amplifier plate side, this form, because power amplifier is vertical with heat radiation rack, and integrated, if the power amplifier of multichannel, then the separating degree of each sound channel is lower, radiating effect is undesirable, circuit reliability is not high, and it is big to take up room, and maintenance is inconvenient.
The purpose of this utility model is to provide a kind of novel power amplifier heat radiation rack, and it can make, and the power amplifier plate is parallel to be close on the heat radiation rack, improves radiating efficiency, strengthens the shield effectiveness of power amplifier, improves the separating degree of each sound channel, offers convenience to maintenance.
The utility model includes substrate and some heat-dissipating fins, and all heat-dissipating fin space certain distances are vertical and be listed on the surface of substrate, is provided with the circuit board supporting and mounting bracket at the back side of substrate.
The utility model is owing to be provided with the circuit board supporting and mounting bracket at the back side of substrate, therefore circuit board can directly be fixed on the supporting and mounting bracket, circuit board becomes parallel relation with the heat radiation rack substrate, so radiating efficiency height, and heat radiation rack obtains to strengthen to the shield effectiveness of circuit, thereby improved the anti-interference between the circuit, in addition, circuit board is become by keeping flat of past to be placed vertically, its occupation space is reduced, only need during maintenance circuit board is extracted out from circuit supporting fixed mount of the present utility model, can overhaul, very convenient.
Accompanying drawing 1 is a front view of the present utility model.
Accompanying drawing 2 is a vertical view of the present utility model.
Accompanying drawing 3 is a upward view of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described.
As shown in drawings, the utility model includes substrate (1) and some heat-dissipating fins (2), all heat-dissipating fins (2) space certain distance also is listed on the surface of substrate (1), and all heat-dissipating fins (2) are all vertical with substrate (1), in order to increase the surface area of heat-dissipating fin (2), to improve radiating efficiency, on two surfaces of heat-dissipating fin (2), establish some strip burrs (3) that are parallel to each other, the back side at substrate (1) is provided with the circuit board supporting and mounting bracket, this supporting and mounting bracket is made of two support chips (4) that are arranged on substrate (1) both sides, the back side, two support chips (4) are relative, the inboard of each support chip (4) is provided with vertical bar shaped draw-in groove (5), during use, circuit board is inserted in the draw-in groove (5) of two support chips (4), circuit board promptly is fixed on the utility model by parallel substrate (1), when circuit board has fault, only need circuit board extraction from the draw-in groove (5) of support chip (4) can be overhauled, when circuit is multichannel, the power amplifier plate of multichannel can be divided into some cell boards, establish the power amplifier of 1～2 sound channel on each cell board.Each cell board is joined a utility model, then that plurality of units is parallel and be listed in the casing, like this, the circuit of power amplifier is because shielding action of the present utility model on each cell board, disturb each other little, the separating degree height, the corresponding the utility model of each element circuit of while, the complete machine radiating efficiency is improved greatly, and a circuit is out of order and only needs to extract a cell board out maintenance simultaneously, and is very convenient.
For the utility model being fixed in the casing.On the lateral surface of two heat-dissipating fins (2) of left and right sides ragged edge, respectively establish a clamp bar slot (6), like this, as long as fix two screws on the bracing frame in casing, the front end of two screws is snapped in two clamp bar slots (6), the utility model promptly is fixed on the interior bracing frame of casing.
The utility model can be used for the heat radiation of various circuit, more apparent its superiority on the bigger power amplifier of heat production.
Claims (3)
1, a kind of power amplifier heat radiation rack, include substrate (1) and some heat-dissipating fins (2), all heat-dissipating fins (2) space certain distance is vertical and be listed on the surface of substrate (1), it is characterized in that being provided with the circuit board supporting and mounting bracket at the back side of substrate (1).
2, power amplifier heat radiation rack as claimed in claim 1, it is characterized in that described circuit board supporting and mounting bracket is made up of two support chips (4) that are arranged on substrate (1) both sides, the back side, two support chips (4) are relative, and the inboard of each support chip (4) is provided with vertical bar type draw-in groove (5).
3, power amplifier heat radiation rack as claimed in claim 1 or 2 is characterized in that respectively establishing a draw-in groove (6) on the outside of two heat-dissipating fins (2) of left and right sides ragged edge.
