Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1 and Figure 2, a kind of liquid-cooling heat radiator, comprising: the heat-conducting plate 1 for being connect with heat source, heat-conducting plate
1 upper end offers installation groove 2；Copper sheet 3 is set in installation groove 2, and 3 lower end of copper sheet has thermal conductive surface 7 and thermal conductive surface 7
It is tightly attached to 2 inner face of installation groove, 3 both ends of copper sheet are respectively equipped with feed liquor face 4 and out liquid level 5, and feed liquor face 4 is equal with liquid level 5 out
For oblique section, several microchannels 6 for coolant liquid circulation are formed in copper sheet 3,6 one end of microchannel is cut in feed liquor face 4
It is segmented into lotus root shape inlet, 6 other end of microchannel is cut into lotus root shape liquid outlet by liquid level 5 out.
Because copper sheet 3 has thermal conductive surface 7, and thermal conductive surface 7 is resisted against 2 inner face of installation groove, so heat-conducting plate 1 can incite somebody to action
Heat on heat source is conducted to copper sheet 3, and microchannel 6 is formed on copper sheet 3, can recycle inflow coolant liquid in microchannel 6, when
Coolant liquid can take away the heat on copper sheet 3 when circulating, realize heat spreading function, and in traditional technology, because microchannel 6
Diameter is very small, and the power of driving motor power is constant, so flow velocity of the coolant liquid in microchannel 6 is very slow, this
It is very poor that sample will lead to heat dissipation effect, in the application, the feed liquor face 4 and both ends of microchannel 6 are cut into lotus root shape respectively by liquid level 5 out
Inlet and lotus root shape liquid outlet, the i.e. both ends of microchannel 6 are that port is elliptical shape made of beveling, thus can
Enough increase the opening area at 6 both ends of microchannel, so that the feed liquor and pressure of liquid becomes smaller out in microchannel 6, due to driving
Power of motor is constant, so flow just will increase when pressure becomes smaller, so that more coolant liquids is made to participate in heat exchange,
Improve the heat dissipation performance of radiator.
Coolant liquid uses pure water, is on the one hand conducive to environmental protection, on the other hand reduces coolant liquid cost.
Angle between feed liquor face 4 and thermal conductive surface 7 is between 30 degree to 90 degree.
The angle between liquid level 5 and thermal conductive surface 7 is between 30 degree to 90 degree out.
Feed liquor face 4 is oblique section with liquid level 5 out, different by two oblique sections in the case where different demands
Inclination angle change the area of section size of both lotus root shape inlet and lotus root shape liquid outlet, and then enable to microchannel 6
The pressure at both ends is different, can make the feed speed of coolant liquid and liquid speed degree changes out, feed liquor face 4 and thermal conductive surface
When angle between 7 is 30 degree, the flow that 6 both ends of microchannel are flowed through in the unit time increases, and more coolant liquids, which absorb, receives copper
The heat of plate 3 can realize that the cold/heat exchange efficiency of copper sheet 3 maximizes, and the angle between liquid level 5 and thermal conductive surface 7 is 30 out
It spends between 90 degree, angle is smaller, and coolant rate is bigger in the unit time, but 7 outlet port copper sheet of thermal conductive surface, 3 thickness becomes
Thin, temperature increases, and exchange capability of heat decline needs comprehensive selection to go out the angle between liquid level 5 and thermal conductive surface 7, realizes and preferably dissipates
Thermal effect.
Microchannel 6 is regularly arranged in a lateral direction, and microchannel 6 is integrated with the copper sheet 3 and is made.It is utilized in the application
Metal-gas eutectic directional solidification method prepares porous copper product, and wherein microchannel 6 is regularly arranged along solidification direction, such side
Formula can be realized inexpensive batch production, for making a kind of microchannel 6 of round straight hole structure, further decreases and is produced into
This.
Installation groove both ends are respectively provided with coolant inlet 8 and cooling liquid outlet 9, and feed liquor face is located at the coolant liquid and enters
At mouth 8, liquid level 5 is located at the cooling liquid outlet 9 out.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
