Description
Technical field
The utility model belongs to high-power electric appliance technical field of heat dissipation, and in particular to a kind of working fluid submerges cooled entirely
Power amplifier in transmitter unit.
Background technology
All solid-state transmitter enters world market history for many years, and it is small, stable and reliable in work with long lifespan, maintenance
And obtain the favor of user.But the power amplifier chips power consumption of emitter is very big, higher is required to cooling system.Power amplifier in transmitter list
The cooling system of member mainly uses two ways at present:Traditional air-cooled and water-cooling base plate radiator cooling.
It is economical and practical using the cooling system of transmitter of air cooling way, it is high using reliability in environment preferably area, but
Air cooling way has the shortcomings that its is intrinsic --- (1) noise is big, and especially operationally gentle stream passes through power amplifier list to high-power blower
Larger noise can be all produced when first；(2) high is required to dust-filtering system, air cooling way emitter is to the requirement of computer room air purity
Higher, otherwise the ventilating duct of power amplifier unit is easy to block up；(3) high is required to environment temperature, the environment temperature of air cooling way can be straight
The power output for having influence on emitter is connect, in some high temperature area or summer high-temperature time, various methods and measure must be all used
Emitter is kept to be in constant temperature working condition to reduce the temperature (plus air-conditioning etc.) of environment；(4) air-cooled emitter is due to air channel
Design can be in occupancy machine big quantity space, general volume all can be very big, and the big area of water content can cause machine in air
The corrosion of interior ventilating duct, highlands can cause radiating effect poor because of rarefaction of air.
Had many good qualities using the emitter of water-cooling base plate radiator cooling is relatively air-cooled, small volume, noise are low；Radiating effect
Rate is high, is suitable for high-power transmitter.Water-cooling base plate radiating is that the multichannel power amplifier module of operating circuit is placed on heat sink,
Provided with closing cooling pipe in heat sink；Cooling pipe is communicated with an extraneous liquid circulating apparatus；The power produced by pump,
The liquid circulation in closed system is promoted, the heat that the power amplifier chips that radiator absorbs are produced takes the bigger radiating of area to and filled
Put, radiated.Liquid after cooling is back to heat sink again, so moves in circles.This water-cooling base plate radiator is deposited
In following shortcoming：(1) leakage, once leakage will cause to shut down；(2) incrustation scale is easily produced in water-cooling base plate, once incrustation scale
Thermal conductivity factor, influence radiating will be greatly reduced in formation；(3) it is continuously increased with the power density of power amplifier chips, water-cooling base plate
Radiator can not meet radiating requirements at last.
Utility model content
In view of the shortcomings of the prior art, cooled power amplifier in transmitter list is submerged entirely the utility model proposes a kind of working fluid

Connected between the outside of the feed tube and drain pipe by circulating pump and pipeline.
In the above-mentioned technical solutions, power amplifier chips are on substrate, and substrate is connected by structural member with casing, is radiated
During process, circulating pump is opened, and the insulation cooling oil for radiating is from the entrance of the feed tube of casing trailing flank, and from cabinet front face
Drain pipe outflow, due to drain pipe setting height(from bottom) be higher than setting height(from bottom) of the power amplifier chips in casing, so working as cooling oil
When being flowed out from drain pipe, directly contact and all submerged with power amplifier chips first, then by the whole bands of the heat of power amplifier chips
Go out, and distribute the heat of acquisition during the cooling oil outer loop that insulate, then cooling oil is recycled.
It is preferred that, the signaling interface, power interface, lamina tecti and casing joint are sealed using seal gasket, can be with
Prevent leakage.
It is preferred that, radiator is additionally provided with the external connection pipeline of the feed tube and drain pipe, can by radiator
To accelerate heat of the insulation cooling oil in cyclic process to distribute, it is ensured that insulation cooling oil keeps low temperature before re-circulation.
It is preferred that, filter is additionally provided with the external connection pipeline of the feed tube and drain pipe, filter can be gone
Except the impurity that insulation cooling oil may be brought into cyclic process, prevent that impurity from producing deposition on power amplifier chips, influences power amplifier
Normal use.
A kind of working fluid that the utility model is provided submerges the beneficial effect of cooled power amplifier in transmitter unit entirely：
(1) this working fluid submerges cooled power amplifier in transmitter unit using insulation cooling oil as cooling working medium entirely, by
It is more than the cold radiating efficiency of liquid under air, the same terms in the specific heat capacity of insulation cooling oil to cool down apparently higher than air, and absolutely
