Description
Technical field
The utility model belongs to power electronics cooling device technical field, and in particular to one kind is applied to circuit power element
The cooling line device of radiating.
Background technology
In recent years, it is effective to improve first device with the continuous increase and the rapid raising of power grade of electric device capacity
The adaptability of the thermal reliability and various severe environmental conditions of part and equipment becomes particularly important, the heat exchange of component and equipment
Universal attention is obtained.
At present, the measure used both at home and abroad in cooling radiating mainly has：Natural cooling, air blast cooling, liquid cooling etc..
Liquid cooling, which is generally used, configures pump to maintain the circulation of liquid in traditional snake pipe indirect heat exchange, system, cooling can indirectly
Avoiding component, directly about coolant is contacted, and reduces the pollution of component in itself, its is simple in construction, easily manufactured, but heat exchange effect
Rate is low, easy fouling, causes the rise of chip temperature, if without adequate measures, it is possible to exceedes chip temperature and permits
Perhaps maximum junction temperature, so as to cause the deterioration of device performance so that damaging.So in the design, appropriate cooling measure is selected,
And reasonably designed, it is that the potentiality for making component are not fully exerted, improves the indispensable important ring of equipment dependability
One of section.
Utility model content
The purpose of this utility model is to provide a kind of suitable for high heat flux, high power density and hot environment element
Radiating has high request, and cooling pipe is not easy fouling, and can improve the Control device of liquid cooling of heat exchange efficiency.
To achieve the above object, the utility model provides following technical scheme：
A kind of cooling line device applied to circuit power element radiating, including coldplate 1, if being provided with coldplate 1
Dry parallel cavity 2, cavity 2 is embedded to be cased with cooling line, and cooling line is made up of some cooling tubes 3 be arrangeding in parallel, each
Cooling tube 3 is closely nested in each cavity 2 respectively, in use, coolant is via the coolant inlet for being located at the one end of cavity 2
5 enter, and flow through after cooling tube 3 through being flowed out by cooling liquid outlet 6.
It is preferred that, the surface radial direction of cooling tube 3 is staggeredly equipped with oblong aperture 4, and many along being axially arranged with for cooling tube 3
The individual oblong aperture 4 being staggered.
It is preferred that, cooling line is made up of aluminum alloy materials.
Compared with prior art, the beneficial effects of the utility model are：
1）Oblong aperture staggeredly is opened up on cooling tube so that the liquid of longitudinal flow in straight tube is formed small at edge
Annular return, so as to add the less turbulence of liquid in pipe flowing, improves the coefficient of heat transfer in pipe.
2）Because cooling liquid produces impact in cooling tube at flow forward and oblong aperture, thus play On Line Foul Removing Technology and
The effect of antiscale.
3）Under the same conditions, the heat of heating power element is directly quickly taken away in the coolant for cooling down Bottomhole pressure
Amount, so that device volume can be reduced under the same conditions.

Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
As shown in figure 1, a kind of cooling line device applied to circuit power element radiating, including coldplate 1, coldplate
Be provided with some parallel cavitys 2 in 1, cavity 2 is embedded to be cased with cooling line, cooling line by it is some be arranged in parallel by aluminium alloy
The cooling tube 3 that material is made is constituted, and each cooling tube 3 is closely nested in each cavity 2 respectively, in use, coolant is passed through
Entered by the coolant inlet 5 for being located at the one end of cavity 2, flowed through after cooling tube 3 through being flowed out by cooling liquid outlet 6.
As shown in Figures 2 and 3, the surface radial direction of cooling tube 3 is staggeredly equipped with oblong aperture 4, and along the axle of cooling tube 3
To provided with multiple oblong apertures 4 being staggered.
The utility model, in six pulsation 300Hz diode rectification devices, during work, inputs the specified friendship of three-phase specifically used
Voltage 690V, electric current 900A are flowed, voltage x current passes through provided with diode above heat abstractor, exports DC voltage 940V, output
DC current 1300A, 20 degree of room temperature, through low voltage test data such as following table：
Power diode operating temperature by 77 degree of blank pipe heat abstractor be down to 65 degree it is stable, according to silicon diode characteristic, outside
The timing of making alive one, diode temperature often increases by 10 degree, and forward voltage about reduces by 20~25mV, and reverse current is increased about
One times, loss substantially increase, efficiency declines；When temperature is down to 66 degree from 77 overall transformation efficiency is calculated according to diode losses
1.2~1.8 times can be lifted.
