Detailed description of the invention
Below coordinate accompanying drawing and preferred embodiment of the present utility model, further set forth the technological means that the utility model is taked for reaching predetermined utility model object.
Refer to shown in Fig. 1 and Fig. 2, the first embodiment of interior tubular type temperature-uniforming plate of the present utility model includes two plate bodys 10 and four inner tubes, and wherein four inner tubes include a loop-type heat exchange pipe fitting 20 and three heat pipes 30.
Aforesaid two plate bodys 10 mutually combine, and in the present embodiment, plate body 10 is approximately slightly square, but not as limit, also can be other shapes; Each plate body 10 includes a medial surface 11 and a lateral surface 12, and in the present embodiment, the medial surface 11 of each plate body 10 is concaved with a corrugated heat pipe 13, the periphery of the edges abut plate body 10 of corrugated heat pipe 13; The medial surface 11 of two plate bodys 10 reclines mutually, and therefore the corrugated heat pipe 13 of two plate bodys 10 is connected and communicates.
Refer to shown in Fig. 1 to Fig. 4, loop-type heat exchange pipe fitting 20 is located in the corrugated heat pipe 13 of two plate bodys 10, and includes a cavity 21 and a body 22; Cavity 21 has an inner space and a separating part 213, and separating part 213 is separated into one by this inner space and is subject to hot cell 211 and a return passage 212, and separating part 213 is low heat-conducting, and is thermal conductivity factor furthermore lower than 100 material, but not as limit; On separating part 213, be penetrated with at least one fine road 214, communicated (as shown in Figure 4) by those fine roads 214 by hot cell 211 and return passage 212; The two ends of body 22 all connect cavity 21, and communicate with being subject to hot cell 211 and return passage 212 respectively, be subject to the sectional area in hot cell 211 and the sectional area of return passage 212 identical, and be all greater than the sectional area of body 22, the sectional area of body 22 is greater than the sectional area in each fine road 214; Body 22 is set to a rectangle along the periphery ring winding of plate body 10 in the present embodiment, but not as limit, also can encompass other shapes, or is relatively positioned at the centre of plate body 10; In the present embodiment, the internal face of each fine road 214 and body 22 is all provided with capillary structure, but not as limit.
Refer to shown in Fig. 2 and Fig. 3, aforesaid three heat pipes 30 are located in the corrugated heat pipe 13 of two plate bodys 10, one end of three heat pipes 30 all abuts in the outside wall surface that is subject to hot cell 211 of cavity 21 of loop-type heat exchange pipe fitting 20, three heat pipes 30 are all that straight line extends, and the angle of wantonly two adjacent heat pipes 30 is about 45 degree, with this, three heat pipes 30 can be spread on whole plate body 10 equably; In the present embodiment, the internal face of heat pipe 30 is provided with capillary structure, but not as limit.
In the cavity 21 of loop-type heat exchange pipe fitting 20 and body 22 and in heat pipe 30, be all provided with working fluid, working fluid can be water or refrigerant, but with this, both are not limited.
Refer to shown in Fig. 2 to Fig. 4, when the utility model uses, wherein a plate body 10 abuts in thermal source 40, or utilize heat conducting material that the heat of thermal source 40 is transmitted on plate body 10, and the cavity 21 of loop-type heat exchange pipe fitting 20 be subject to hot cell 211 just corresponding at thermal source 40 places or heat conducting material place receive heat, be subject to working fluid in hot cell 211 to flash to gaseous state because of heat, and working fluid in return passage 212 is not directly heated and therefore remains on liquid state, in addition, more can effectively the keep from heat heat of chamber 211 of the separating part 213 of low heat-conducting is delivered to return passage 212, and the return passage 212 of gaseous working fluid has just produced different saturated vapour pressures from the hot cell 211 that is subject to of liquid working fluid, and then make gaseous working fluid will move to liquid working fluid place, but the capillary pressure effect in the fine road 214 of separating part 213 makes gaseous working fluid cannot pass through fine road 214, therefore gaseous working fluid just can arrive at return passage 212 around a circle along body 22, and when gaseous working fluid is in the process of body 22 interior movements, can be constantly by dissipation of heat out, and therefore transfer heat to plate body 10 everywhere, gaseous working fluid is finally cooling to be become liquid state and gets back to return passage 212, at this moment fine road 214 is again brought into play capillary pressure effect and liquid working fluid in return passage 212 is moved to and is subject in hot cell 211, and be again subject to thermal evaporation and repetitive cycling, can effectively the heat of thermal source 40 be evenly delivered to plate body 10 everywhere with this loop-type heat exchange pipe fitting 20.
In addition, one end of each heat pipe 30 abuts in the outside wall surface that is subject to hot cell 211 of the cavity 21 of loop-type heat exchange pipe fitting 20, can receive equally and be subject to the heat in hot cell 211 and the working fluid at heat pipe 30 these end places is evaporated with this, the same other end that can move to heat pipe 30 because of the difference of saturated vapour pressure after working fluid evaporation, and in moving process, transmit heat to plate body 10 everywhere, gaseous working fluid is cooled to after liquid state because the capillary pressure effect of heat pipe 30 internal faces is got back to initiating terminal and is again heated; Can effectively the heat of thermal source 40 be evenly delivered to plate body 10 everywhere with this heat pipe 30.
No matter be loop-type heat exchange pipe fitting 20 or heat pipe 30, it all carrys out transferring heat by the movement of working fluid, and then has effect of flash heat transfer.
