Abstract
The utility model relates to a heat radiator for power amplifiers, wherein, a baffle plate of the radiator is fixed on a blade type heat radiator through an upper and a lower connection racks and forms a single flow heat radiator which is fixed on a pedestal. When the utility model is used, air enters the spaces among the radiation fins of the single flow heat radiator from the air intake grids of the pedestal, and is forcibly exhausted out of the heat radiator by a blowing fan which is fixed on one side plate of a rear cover or an upper cover after absorbing heat, which can meet the requirements of fast heat radiation with high efficiency. A power amplifier with the utility model has the advantages of less damage, longer service life of the internal components, and higher quality of signal amplification.
Description
The utility model relates to the parts of power amplifier.
Power amplifier in use, its power tube is main heater element.If heat can not in time spread out, will make component wear.So power amplifier all is equipped with heat abstractor.Common structure is: power tube is fixed on the base plate of open type radiator, the open type radiator directly or by support is fixed on the base plate, base plate enter grid in the machine with the corresponding part of radiator for making air, loam cake flow out the grid of power amplifier with the corresponding part of radiator for making hot-air in the machine.When the heat abstractor of this structure uses, because of the power tube heating, and heat conducted to radiator, after radiator is heated again with the air in the heat transferred radiator, hot-air rises and flows out to outside the machine, cold air then replenishes from the grid of base plate enters radiator in the machine, and the heat in the machine sheds by constantly flowing of air, forms free convection; Also can dispel the heat simultaneously by casing.People tend to conveniently with paying no attention to newspapers and periodicals etc. be placed on power amplifier on cover, cover its grid, when using power amplifier in this case, can be untimely because of dispelling the heat, easily bring and damage and components and parts are reduced useful life to machine; Simultaneously, the radiator heat-dissipation speed of this structure is slower.
The purpose of this utility model is, radiating efficiency was higher and make the non-damageable heat abstractor of power amplifier when a kind of use was provided.
The technical scheme that realizes the utility model purpose is (referring to Fig. 1 and Fig. 2): this heat abstractor has base (1), loam cake (2), bonnet (3) and blade radiator (5), base (1) is provided with grid (12), base (1), loam cake (2) and bonnet (3) are fixedlyed connected each other and are formed a construction package, blade radiator (5) is arranged in this construction package and is positioned at the top of the grid (12) of base (1), and the base plate (51) of blade radiator (5) is provided with connecting hole or the connector that is used for fixing power tube; Its design feature is: this heat abstractor also has baffle plate (61), last link (62), following link (63) and fan (7), baffle plate (61) is arranged on the position relative with the base plate (51) of blade radiator (5) and with the blade of blade radiator (5) and contacts, baffle plate (61) is fixed on blade radiator (5) by last link (62) and following link (63) and upward constitutes the straight flow radiator, the straight flow radiator is fixed on the base (1), the upper end of straight flow radiator and loam cake leave the space between (2), fan (7) is fixed on the side plate (22) or bonnet (3) of loam cake (2), and the corresponding site of the plate body of fan attachment is provided with air-out grid or exhaust vent.
The upper plate (21) of above-mentioned loam cake (2) is a flat board, and fan (7) is fixed on the bonnet (3).This device also has metal header board (4), and header board (4) is fixed on the construction package that base (1), loam cake (2) and bonnet (3) form and is positioned at the front end of straight flow radiator.
The utlity model has positive effect: (1) is because of forming a plurality of " pipeline spaces " between the baffle plate of this heat abstractor and the blade radiator, air flows into " pipeline space " through the base plate grid, absorb the heat of radiator and rise, under the twitch of fan, form enforceable air stream, hot-air is flow to rapidly outside the machine, and the efficient that this enforceable air stream is taken away heat significantly improves.(2) radiating efficiency because of this device significantly improves, thus the height of blade radiator can be reduced, thus cost-saved.(3) upper plate of the loam cake of this device is the flat board of a no perforate, can make its processing comparatively simple, also can play simultaneously and reduce the effect that dust falls into chance in the machine.(4) the metal header board is set and not only can strengthens the structural stability of whole casing, and help the relevant device that is arranged on the panel is played shielding action.(5) fan of this device continues heat is in time discharged outside the machine, therefore, uses the power amplifier of this device not fragile, components and parts wherein are also longer useful life, and the quality that signal is amplified improves.
Fig. 1 is a kind of three-dimensional exploded view of the present utility model.
Fig. 2 is mounted to a kind of schematic diagram of cutting open behind the heat abstractor for each parts among Fig. 1.
The schematic diagram of air flow direction when Fig. 3 is heat abstractor shown in Figure 2 work.
Fig. 4 is the schematic diagram on power tube the is fixed on radiator shown in Figure 3.
The utility model will be further described below in conjunction with drawings and Examples.
Embodiment 1,
See Fig. 1 and Fig. 2, this heat abstractor has base (1), loam cake (2), bonnet (3), metal header board (4), blade radiator (5), baffle plate (61), goes up link (62), following link (63) and fan (7).Base (1) is provided with bar shaped air intake grid (12), and bonnet (3) is provided with arc air-out grid (32), and the upper plate (21) of loam cake (2) is a flat board, and the base plate (51) of blade radiator (5) is provided with the connecting hole that is used for fixing power tube.Base (1), loam cake (2) and bonnet (3) are fixedlyed connected each other and are formed a construction package, and blade radiator (5) is arranged in this construction package and is positioned at the top of the air intake grid (12) of base (1).Baffle plate (61) is arranged on the position relative with the base plate (51) of blade radiator (5) and with the blade of blade radiator (5) and contacts, baffle plate (61) is fixed on blade radiator (5) by last link (62) and following link (63) and upward constitutes the straight flow radiator, the straight flow radiator is fixed on the base (1), and the upper end of straight flow radiator and loam cake leave the space between (2).Fan (7) is fixed on the bonnet (3), and the air-out grid (32) that is positioned at bonnet (3) is located.Metal header board (4) is fixed on the construction package that base (1), loam cake (2) and bonnet (3) form and is positioned at the front end of straight flow radiator.
