Abstract
The utility model discloses an air flow radiating structure for a power amplifier, which comprises a radiating aluminum pipe, a fan and air flow guiding devices. The air flow guiding devices are arranged on two sides of the radiating aluminum pipe respectively, wherein the air flow guiding device at an air inlet end of the radiating aluminum pipe is connected with the fan, an air outlet end of the radiating aluminum pipe is connected with a machine case in sealing mode through another air flow guiding device so as to enable hot air to be discharged to the outside of the machine case directly and enable air to circulate smoothly in centralized mode to take away heat of an amplifier radiating aluminum pipe fast, and radiating efficiency is improved by 30%. The air outlet end is closely combined with the machine case so as to enable the hot air inside a machine to be discharged to the outside of the machine case directly and prevent the hot air from circulating inside the machine to enable the temperature to be higher and higher. The air flow guiding devices adopt a plastic material which is low in heat conducting rate and prevent high temperature of the radiating aluminum pipe from being transferred to the machine case, therefore temperature of a casing of the machine case is reduced, and safety of products is improved.
Description
Technical field
The utility model discloses a kind of wandering heat structure of power amplifier air that is used for, and divides by International Patent Classification (IPC) (IPC) to belong to audio amplifier power amplifier manufacturing technology field.
Background technology
The radiator structure of existing power amplifier generally comprises the fan B of amplifier heat radiation aluminum pipe A and one of which side, as shown in Figure 1; Heat radiation aluminum pipe in addition side is connected and fixed by bolt of long stem or other connectors and cabinet; Because therefore heat radiation aluminum pipe temperature is higher, conducts to cabinet, for avoiding aluminum pipe high temperature; The aluminum pipe port of export and cabinet leave the gap; Air communication passing through fan in the power amplifier is also discharged outside cabinet by the heat radiation aluminum pipe, but because the gap of heat radiation aluminum pipe and cabinet, the part air-flow is fed back in the cabinet and does not have discharge in time; In addition, in the existing structure, hot-air plays reflection at heat radiation aluminum pipe section part, hinders circulation of air, arrow as shown in Figure 2, and then influence radiating effect.
Summary of the invention
To the deficiency of prior art, the utility model provide a kind of rational in infrastructure, radiating efficiency is high is used for the wandering heat structure of power amplifier air.
For achieving the above object, the utility model is realized through following technical scheme:
A kind of wandering heat structure of power amplifier air that is used for; Comprise heat radiation aluminum pipe, fan and air deflector; Heat radiation aluminum pipe both sides are installed air deflector respectively; The air deflector of aluminum pipe air inlet end of wherein dispelling the heat links to each other with fan, and heat radiation aluminum pipe air opening end directly discharges outside the cabinet hot-air through airtight connection of another air deflector and cabinet.
Further; Described air deflector is provided with and the interior corresponding some bafflers of each layer heating panel of the aluminum pipe that dispels the heat vertically; And the distolateral and heating panel that baffler contacts with heating panel maintains an equal level; Another of baffler is distolateral to be cusp-shaped, and the air-flow that fan is blown into can unobstructedly all enter into heat radiation aluminum pipe passage, does not hinder circulation of air and the air reflection does not take place.
Further, the outer diversion cavity of the baffler of said air deflector is the water conservancy diversion anchor ring that cambered surface increases gradually.
The utlity model has following beneficial effect:
1, the utility model is that inlet and outlet at amplifier heat radiation aluminum pipe respectively increases a tool air guide structure; Air is installed according to this concentrate circulation smoothly more; Thereby take away the heat of amplifier heat radiation aluminum pipe fast; It is about 30% to improve radiating efficiency, or uses aluminium still less to reach the same radiating effect of traditional approach;
2, the air opening end of the utility model combines with cabinet is airtight, and the interior hot-air of machine is directly discharged outside the cabinet through this device, avoids hot-air in machine, to circulate and makes temperature long-pending more high more;
3, the utility model air deflector is owing to adopt the low plastic cement material of thermal conductivity, and isolated amplifier heat radiation aluminum pipe and cabinet are so just avoided the direct conduction of high temperature of amplifier heat radiation aluminum pipe to give cabinet, thereby reduced the temperature of casing, improve Product Safety.

Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Embodiment: see also Fig. 3 to Fig. 5; A kind of wandering heat structure of power amplifier air that is used for; Comprise heat radiation aluminum pipe 1, fan 2 and air deflector 31,32; Heat radiation aluminum pipe 1 both sides are installed air deflector 31,32 respectively, and the air deflector 31 of the aluminum pipe air inlet end that wherein dispels the heat links to each other with fan 2, and heat radiation aluminum pipe air opening end directly discharges outside the cabinet hot-air through airtight connection of another air deflector 32 and cabinet.Air deflector 31 is provided with the some bafflers 311 corresponding with each layer heating panel in the aluminum pipe 11 of dispelling the heat vertically; And the distolateral and heating panel that baffler contacts with heating panel maintains an equal level; Another of baffler is distolateral to be cusp-shaped 3110; The air-flow that fan is blown into can unobstructedly all enter into heat radiation aluminum pipe passage, and circulation of air is as shown in Figure 5, does not hinder circulation of air and the air reflection does not take place.The outer diversion cavity of the baffler of air deflector is the water conservancy diversion anchor ring 312 that cambered surface increases gradually.
The utility model is that the inlet and outlet at amplifier heat radiation aluminum pipe respectively increases a tool air guide structure; Air is installed according to this concentrate circulation smoothly more; Thereby take away the heat of amplifier heat radiation aluminum pipe fast; It is about 30% to improve radiating efficiency, or uses aluminium still less to reach the same radiating effect of traditional approach.The utility model makes the interior hot-air of machine directly discharge outside the cabinet through this device owing to combine with cabinet is airtight, avoids hot-air in machine, to circulate and makes temperature long-pending more high more.The utility model air deflector adopts the low plastic cement material of thermal conductivity, and isolated amplifier heat radiation aluminum pipe and cabinet are so just avoided the direct conduction of high temperature of amplifier heat radiation aluminum pipe to give cabinet, thereby reduced the temperature of casing, improve Product Safety.
The above record is merely the embodiment that utilizes this origination techniques content, anyly is familiar with modification, the variation that this creation of this art utilization is done, and all belongs to the claim of this creation opinion, and is not limited to embodiment announcement person.
