The connection of cooling line 26 forms cooling circuit, and cooling circuit is provided with liquid pump 27, and liquid pump 27 can use direct current supply or friendship
Stream power supply.Then in the presence of liquid pump 27, cooling liquid can be in cooling line 26 and flow channel for liquids internal circulation flow.Liquid
Pump 27 can use centrifugal pump or immersible pump, and its flow is (1-5) L/min, and its flow is bigger, and the flowing velocity of cooling liquid is got over
It hurry up, radiating effect is better.
Further, it can also set in heat exchanger 28, heat exchanger 28 and be provided with and cooling line on cooling circuit
Multiple heat emission holes are provided with the fluid passage of 26 connections, heat exchanger 28.When cooling liquid is flowed through in liquid cooling matrix 21
Flow channel for liquids when, absorb metal substrate 18 heat；When cooling liquid flows through the liquid in cooling line 26 and heat exchanger 28
During body passage, heat exchange is carried out with extraneous air, extraneous air is transferred heat to.Heat exchanger 28 can specifically use existing skill
The water row's radiator commonly used in art, its area of dissipation can be set according to the heat exchange amount needed for semi-conductor electricity couple 12.
In order to strengthen heat exchange, it can also be provided for dissipating heat exchanger 28 at the heat emission hole of heat exchanger 28
The cooling fan 29 of heat, the air-out direction of cooling fan 29 can also deviate from heat exchanger 28 towards heat exchanger 28, with
Accelerate for the purpose of the air flow around heat exchanger 28, improve the speed that cooling liquid carries out heat exchange with surrounding air.It is cold
But the big I of fan 29 and radiator water row area match, its air quantity, wind pressure parameter selection can be according to semi-conductor electricity
Heat exchange amount and water needed for couple 12 arrange the heat dissipation capacity of radiator to be set.
On the basis of above-mentioned technical proposal, the present embodiment also provides a kind of implementation, can further improve and partly lead
The heat exchange efficiency of body cooling assembly.
Metal substrate 18 is set to aluminium base, the area of aluminium base is 80mm × 90mm, thickness be 1.3mm to 1.7mm,
Preferably 1.5mm.It can be attached between aluminium base and liquid cooling matrix 21 by the way of being spirally connected.In aluminium base towards partly
Conductor galvanic couple can be using chemistry and physical method in aluminium base to laying thermally conductive insulating layer, thermally conductive insulating layer on 12 cold end face
Surface coating form or using one layer obtained from chemical treatment very thin metal heat-conducting and the material of insulation.Also, lead
Thermal insulation layer is engaged by means such as chemistry with hotter side electrode 15.Thermal resistance therefore, between hotter side electrode 15 and thermally conductive insulating layer,
And the thermal resistance of aluminium base itself is relatively small, it is possible to increase heat conduction efficiency.
The heat that then semi-conductor electricity couple 12 is produced on hotter side electrode 15 can be Jing Guo smaller thermal resistance thermally conductive insulating layer
Aluminium base is directly conducted to, using the good heat conduction of aluminium base, average temperature performance, heat is rapidly transferred to aluminium base towards liquid
The surface of matrix 21, and cooled liquid absorption are cooled down, the diffuser efficiency of heat can be significantly improved, be advantageously implemented high-power
Refrigeration.
