One communication port 332 connects, in this way, absorbing the air of heat can be entered by the first communication port 331 and first circulation pipe 351
Cooler 340, under the cooler 340 effect, heat is absorbed and is discharged by the cooler 340, and the air through cooling leads to
It crosses 352 and first communication port 332 of second circulation pipe to be again introduced into cooling chamber 330 so that the temperature of cooling chamber 330 is dropped
It is low, improve the heat absorption capacity of cooling chamber 330.
For example, being provided with cooling medium in the cooling chamber 330, for example, the cooling medium is air, air is good
Heat transfer medium, the characteristics of easily obtaining, have velocity of liquid assets fast, be easy to transmission, air can rapidly in cooling chamber 330 and
It circulates in cooler 340 so that heat exchanger effectiveness improves, in order to further improve the endothermic effect of the cooling body 300, example
Such as, the cooling medium is coolant, for example, the coolant is cooling water, water has the characteristics that specific heat capacity is big, and with valency
Lattice are cheap, the advantages of being easily obtained, when cooling water circulation in cooling chamber 330, can effectively take away the heat of coldplate 320
Amount, and heat is distributed by cooler 340, since specific heat capacity is big, cooling water can fully absorb the heat of coldplate 320
Amount, and temperature is unlikely to raising excessively, has good endothermic effect.For example, the cooler 340 includes water cooling box 360, institute
State water cooling box 360 goes pipe to be connected with the cooling chamber 330, such as be provided with multiple copper pipes in the water cooling box 360 by cold, institute
It states copper pipe and is connect with the radiating fin 361 being set to outside the water cooling box 360, cooling water is by the heat of the cooling chamber 330
It takes in water cooling box 360, after the copper pipe in the water cooling box 360 absorbs the heat of cooling water, transfers heat to radiating fin
Piece 361, radiating fin 361 distribute heat.
For example, in order to improve the heat absorption efficiency of cooling water in cooling chamber 330, referring again to Fig. 4, the cooling chamber 330

Grain, metallic particles 333 have good heat-conducting effect, can fully absorb the heat of coldplate 320, and metallic particles 333 increases
The contact area with cooling water is added, during flow of cooling water, metallic particles 333 can be filled in multiple angles with cooling water
Tap is touched so that heat fully can be transferred to cooling water by metallic particles 333, improve thermal conversion efficiency.
In order to avoid metallic particles 333 flows out the cooling chamber 330 with the flowing of cooling water, as shown in figure 4, described
First communication port 331 and first communication port 332 of cooling chamber 330 are respectively arranged with strainer 334, the strainer 334
With filter opening, the diameter of the filter opening is less than the diameter of the metallic particles 333, it should be understood that the metallic particles 333
Diameter cannot be excessive, if the diameter of metallic particles 333 is excessive, the quality of metallic particles 333 increases therewith, then influence described in
The mobility of metallic particles 333 so that metallic particles 333 can not be moved fully with the flowing of cooling water, reduce metal
The contact frequency of particle 333 and cooling water, and the diameter of metallic particles 333 is also unsuitable too small, too small then metallic particles 333 is easy
It is lost in from cooling chamber 330, and in order to avoid the too small metallic particles 333 of diameter is lost in, then the diameter of filter opening then will accordingly subtract
Small, the reduction of the diameter of filter opening then reduces the mobility of cooling water, in order to improve the flexibility ratio of metallic particles 333, and causes
The more flowability of cooling water, for example, the metallic particles 333 a diameter of 3mm~6mm, a diameter of 1.8mm of filter opening~
3.5mm；Preferably, 333 a diameter of 5mm of metallic particles, a diameter of 3mm of filter opening, in this way, metallic particles 333 has
Smaller volume and quality, flexibility ratio is higher, can be moved with flow of cooling water and quickly, increases the contact frequency with cooling water,
On the other hand, the control of filter opening can abundant filtering metal particle 333, metallic particles 333 is avoided to be lost in, and with good logical
The property crossed so that cooling water has preferable mobility, so that cooling water can rapidly take away heat.
In order to further improve endothermic effect, for example, the coolant is ethyl alcohol, ethyl alcohol has volatile characteristic, when
Ethyl alcohol is heated readily volatilized in the cooling chamber 330, can absorb the heat of the coldplate 320 rapidly, when ethyl alcohol circulates
During to cooler 340, heat is released under the action of cooler 340, ethyl alcohol cohesion is liquid, is circulated again into cooling chamber 330
It is interior, it is achieved thereby that the cycle of heat absorption and heat dissipation, substantially increases the radiating efficiency of coldplate 320.
For example, the cooling medium is liquid nitrogen, liquid nitrogen has extremely low temperature, has extraordinary endothermic effect, when
Liquid nitrogen during circulation, can absorb the heat of cooling version as quick as thought in cooling chamber 330 so that cooling version has extraordinary heat absorption
Effect, can be rapidly by the heat absorption of thermal insulation board 200 so that laser module 100 works at a normal temperature, substantially increases
The service life of laser module 100.
In order to further improve the cooling effect of cooling body 300, for example, the cooling medium is refrigerant, for example, institute
Refrigerant is stated as R417A, for example, as shown in figure 5, the cooler 340 includes compressor 341, throttle valve 342 and condenser
343, one end of the compressor 341 is connect with 343 one end of condenser, the other end and the throttle valve 342 of the condenser 343
One end connects, and the other end of the throttle valve 342 is connect with one end of cooling chamber 330, the other end and pressure of the cooling chamber 330
The other end of contracting machine 341 connects, and in concrete application, compressor 341 works, and is that high pressure gaseous freezes by refrigerant compression
Agent, refrigerant enter condenser 343 after compression, and under the cooling effect of condenser 343, the gaseous refrigerant of high temperature and pressure is cold
But it is the liquid refrigerant of cryogenic high pressure, cryogenic high pressure liquid refrigerant becomes low-temp low-pressure under 342 antihypertensive effect of throttle valve
Liquid refrigerant after low-temp low-pressure liquid refrigerant enters cooling chamber 330, absorbs the heat in cooling chamber 330, rapid to volatilize,
So that the temperature of cooling chamber 330 and coldplate 320 reduces rapidly, so that the heat of thermal insulation board 200 is largely absorbed, volatilization
It after gaseous refrigerant afterwards enters compressor 341, is compressed, is constantly recycled with this process again, worked in laser module 100
When working environment for 100 low temperature of laser module, extend the service life of laser module 100.
In order to further improve the heat absorption of the coldplate 320 and the capacity of heat transmission, please referring also to Fig. 6 and Fig. 7, described cold
But cooling capillary 325 is provided in plate 320, for example, the cooling capillary 325 is connected with the cooling chamber 330, in this way,
The contact area of cooling chamber 330 and coldplate 320 can be increased by the cooling capillary 325, further improve cooling chamber
330 heat absorption efficiency so that the heat of the thermal insulation board 200 can efficiently be transmitted to cooling chamber by the coldplate 320
330, and pass through cooling chamber 330 and distribute.
For example, coolant is provided in the cooling capillary 325, such as the coolant is cooling water, for example, described
Cooling water is by being circulated to cooling capillary 325 in cooling chamber 330 so that cooling water can be contacted fully with coldplate 320, cooling
Water can fully absorb the heat of coldplate 320, and take away heat in the cyclic process of cooling water, and distribute.
It should be understood that the diameter of the cooling capillary 325 should not be too large, the diameter of excessive cooling capillary 325
The heat absorption capacity for causing coldplate 320 is declined, the coolant can not also be caused fully to be contacted with the coldplate 320, and
The diameter of the cooling capillary 325 is also unsuitable too small, the stream that the diameter of too small cooling capillary 325 will influence coolant
It is logical, in order to increase the contact area of coolant and coldplate 320, and improve stream of the coolant in cooling capillary 325
Logical speed, for example, cooling 325 diameter of capillary is set as 2mm~6mm, it is preferable that cooling 325 diameter of capillary
It is set as 3mm~5mm, it is preferable that cooling 325 diameter of capillary is set as 4mm, for example, being set in the coldplate 320
There are multiple cooling capillaries 325, what smaller 325 to one, the capillaries of cooling of such diameter multiple in this way were relatively large in diameter
The surface area bigger of capillary 325 is cooled down, so as to considerably increase the contact area of coolant and the coldplate 320, is improved
The heat absorption capacity of coolant, on the other hand so that coolant can swimmingly circulate in the cooling capillary 325, carry
High heat exchanger effectiveness.It is more uniformly distributed in order to enable coolant can be contacted with the coldplate 320, for example, multiple described cold
But capillary 325 is uniformly arranged in the coldplate 320, for example, multiple cooling capillaries 325 are parallel to each other and uniform
It is arranged in the coldplate 320, for example, as shown in fig. 7, multiple cooling capillaries 325 are in head and the tail sequentially connected " U "
Shape is set, and on the one hand increases the contact area of coolant and coldplate 320 so that coolant and each position of coldplate 320
Contact is more uniformly distributed, and on the other hand allows coolant in the cooling chamber 330 and cooling 325 inner recirculation flow of capillary
It is logical, further improve heat exchanger effectiveness.
In order to further improve the heat absorption of the coldplate 320 and heat-sinking capability, as shown in Figure 8 and Figure 9, the cooler
Structure 300 includes multiple coldplates 320, and the coldplate 320 includes sequentially connected first cooling layer 321, the second cooling layer 322
With third cooling layer 323, first cooling layer 321 is connect with the thermal insulation board 200, for example, first cooling layer 321,
Second cooling layer 322 and the integrated forging molding of third cooling layer 323, for example, first cooling layer 321, the second cooling layer 322
The metal of unlike material is respectively set to third cooling layer 323, for example, first cooling layer 321, the second cooling layer 322
It is respectively the materials synthesis of unlike material with third cooling layer 323, for example, first cooling layer 321 is set as heat conduction carbon fibre
Dimension, second cooling layer 322 are set as copper, and the third cooling layer 323 is set as aluminium.
In order to which the heat improved between first cooling layer 321, the second cooling layer 322 and third cooling layer 323 transmits effect
Rate, for example, being provided with silica gel between first cooling layer 321, the second cooling layer 322 and third cooling layer 323.
It should be understood that since first cooling layer 321, the second cooling layer 322 and third cooling layer 323 be not using
Same material is made, therefore first cooling layer 321, the second cooling layer 322 and third cooling layer 323 have different heat conduction
Rate is more uniformly distributed in order to enable the heat of first cooling layer 321, the second cooling layer 322 and third cooling layer 323 is transmitted, is high
Effect, for example, the thickness of first cooling layer 321, the second cooling layer 322 and third cooling layer 323 is sequentially reduced, above-mentioned
In one embodiment, first cooling layer 321 is heat conduction carbon fiber, and the thermal conductivity of heat conduction carbon fiber is 600~900W/ (m*
DEG C), second cooling layer 322 is copper, and the thermal conductivity of copper is 500~600W/ (m* DEG C), and third cooling layer 323 is aluminium, aluminium
Thermal conductivity for 200~300W/ (m* DEG C), for example, first cooling layer 321 is connect with the thermal insulation board 200, described second
Cooling layer 322 and the third cooling layer 323 are sequentially connected to the side far from the thermal insulation board 200, the third cooling layer
323 are located at the outermost of coldplate 320, and first cooling layer 321 can quickly absorb the heat of thermal insulation board 200, and will be hot
To second cooling layer 322, the second cooling layer 322 conducts heat to third cooling layer 323, third cooling layer for amount conduction
323 distribute heat, due to the heat of first cooling layer 321, second cooling layer 322 and the third cooling layer 323
Conductance is gradually reduced, and therefore, in order to enable heat transference efficiency improves, needs to reduce second cooling layer 322 and the third
