Today, with the rapid development of military and civil electronic communication technologies, high performance chips, integrated circuits, and semiconductor circuits are becoming more and more widely used. The power of the heating element is continuously increased, and the heat dissipation of the heating element is increasingly important. The heat dissipation of the heating element is to control the operation temperature (or heat control) of the heating element so as to ensure the stability and reliability of the operation of the heating element. Heat dissipation technology is becoming a very critical technology in the development and development of electronic devices.
At present, the existing three heat dissipation technologies, namely an air cooling technology, a phase-change heat pipe technology and a water cooling technology, can solve the heat dissipation problem of the heating element to a certain extent, but the heat dissipation technologies also have the defects that:
the air cooling technology requires a low room temperature environment, so that the air cooling technology has a large limitation on application occasions.
The phase-change heat pipe can produce the non-condensing steam after long-term use, leads to heat transfer efficiency to reduce, and because the non-condensing steam causes the intraductal pressure to rise for the phase-change heat pipe has the potential safety hazard.
In the water cooling technology, once water leaks, equipment short circuit can be caused, equipment damage is caused, and serious safety accidents can be caused.

The invention can timely and rapidly emit large heat flow and large heat quantity, has large heat flow density and high heat transfer efficiency, can reach 30-2000W/square meter, provides proper working temperature for heating elements, and ensures that the heating elements are at uniform temperature due to excellent temperature uniformity of internal circulation of non-phase-change superconducting heat transfer working media, the working state is balanced, the service life is prolonged, and the non-phase-change superconducting heat transfer working media can rapidly circulate, rapidly and uniformly heat, has small long-distance heat transfer temperature difference and can reach +/-0.5 ℃ at minimum; moreover, the invention has no direction and space requirements when in use, and can realize antigravity conduction.

In order to realize controllable heat transfer direction and enhance system adaptability, as an improvement of the invention, the non-phase-change superconductive internal circulation heat dissipation system further comprises a circulation pump for driving the non-phase-change superconductive heat transfer working medium to flow, and the circulation pump is arranged in the non-phase-change heat transfer pipeline. The invention adopts active and passive starting, has high response speed, small starting temperature difference and no gravity influence.

Detailed Description
Example 1
As shown in figure 1, the non-phase-change superconductive internal circulation heat dissipation system comprises a non-phase-change heat transfer pipeline 1, a heat collector 2 and a heat exchange unit 3, wherein the heat collector 2 and the heat exchange unit 3 are communicated through the non-phase-change heat transfer pipeline 1 and form a circulation loop, a non-phase-change superconductive heat transfer working medium 4 is arranged in the circulation loop, the heat collector 2 collects heat of a heating element, and simultaneously heats the non-phase-change superconductive heat transfer working medium 4, the non-phase-change superconductive heat transfer working medium 4 flows along the non-phase-change heat transfer pipeline 1 to transfer the heat to the heat exchange unit 3, the heat is conducted out by the heat exchange unit 3, and the non-phase-change superconductive heat transfer working medium 4 after heat exchange flows back to the heat collector 2 along the non-phase-change heat transfer pipeline 1 for the next circulation process.
The non-phase-change heat transfer pipeline 1 generally adopts a high-strength metal pipe (such as copper, aluminum, stainless steel and alloy steel) and ensures that the requirement of compatibility with a non-phase-change superconducting heat transfer working medium is met, and the cross section of the non-phase-change heat transfer pipeline can be standard round or special-shaped, and the pipe diameter, the pipe length and the pipe structure have no requirement.
The specific structure of the heat collector is designed according to the structure of the heating element, and the heat collector has no fixed structure form, but the contact area between the heat collector and the heating element is large as much as possible so as to realize the maximum heat collection. In this embodiment, the heat collector is mainly composed of a plurality of longitudinal branches and a pair of transverse pipelines, which are arranged in parallel, and two ends of each branch pipe are respectively connected to the transverse pipelines. The plurality of longitudinal branches can effectively collect heat of the heating element.
The heat exchange unit exchanges heat with the non-phase-change superconducting heat transfer working medium flowing in the non-phase-change heat transfer pipeline. The heat is led out through the non-phase change heat transfer pipeline to exchange heat with the heat exchange unit, and the heat exchange unit can adopt any heat exchange mode and can be liquid cooling or air cooling and compressor refrigeration. For example, when the system is applied to a heating element working area, the circulation loop can be filled with leaked gaseous working media, such as R134a, R22 and the like, so that the problem of short circuit caused by leakage when water is used as the working media is avoided, the system is safe and reliable, and the heat exchange mode of the heat exchange unit can be liquid cooling or air cooling or compressor refrigeration. For example, the heat exchange unit can be led out to a non-heating element working area, and water cooling can be adopted for the heat exchange unit; when the heat exchange unit is applied to a working area with high ambient temperature, the heat exchange unit can be led out to the low ambient temperature, and natural air cooling or fan air cooling is directly adopted, so that the system power consumption is greatly reduced; when the natural environment is poor or the device needs to work at a low temperature, the compressor can be used for refrigeration.
The non-phase-change superconductive heat transfer working medium is distinguished according to the use temperature, and can meet different working environments: the non-phase-change superconductive internal circulation heat dissipation system operates in an environment with the temperature of 0-200K, and the non-phase-change superconductive heat transfer working medium adopts pure substances and compounds in the form of single elements. The pure chemical substance is helium, argon, krypton, nitrogen or oxygen, and the compound is ethane or freon; the non-phase-change superconductive internal circulation heat dissipation system operates in an environment with the temperature of 200-550K, and the non-phase-change superconductive heat transfer working medium adopts freon, ammonia, alcohol, acetone, water or certain organic compounds; the non-phase-change superconductive internal circulation heat dissipation system operates in an environment with the temperature of 500-750K, and the non-phase-change superconductive heat transfer working medium adopts sulfur, mercury, alkali metal or certain compounds, such as a heat transfer agent; the non-phase-change superconductive internal circulation heat dissipation system operates in an environment with the temperature being more than 750K, and the non-phase-change superconductive heat transfer working medium adopts potassium, sodium, lithium, lead, silver, indium or other metals with high melting points, so that the extremely high axial heat transfer density can be achieved.
The working principle of the invention is as follows:
the leakage-proof test is carried out on the non-phase-change superconducting internal circulation heat dissipation system, so that the system is ensured to be filled with working medium after no leakage, and the non-phase-change superconducting heat transfer working medium is filled when the system is kept stand, i.e. is not started to work and is not heated. Taking water as a non-phase-change superconducting heat transfer working medium as an example, filling a pipeline at the ambient temperature to enable the water to fill the whole pipeline, heating the device to the use temperature (or design temperature), wherein the water in the pipeline overflows slightly due to thermal expansion, at the moment, the water in the pipeline is filled in the whole pipeline, the filling amount is far greater than the filling amount of the phase-change heat pipe, the pipeline is packaged in the state, a sparse vacuum area 10 exists above the pipeline after the pipeline is cooled to the ambient temperature after the filling is completed, and the overflow filling mode is simple and quick, as shown in fig. 2, and can ensure good vacuum degree. The complex operation of different working mediums caused by different expansion coefficients can be avoided, and the filling quantity of the system is ensured.
As shown in figure 3, when the system works, low-temperature steam is generated by continuously heating and heating up water near a rare vacuum area, vacuum gradually disappears, heating is continued, non-phase-change heat transfer is started, liquid phase expansion is generated by water in a pipe cavity, and meanwhile, a gas phase working medium is compressed until the water fills the whole pipe cavity, a small amount of saturated steam space is reserved in a small part above the pipe cavity, and when the expansion work process tends to be stable, the heat pipe reaches the use environment (or design environment) of the heat pipe. At this moment, the water in the tube cavity is in a gas-liquid mixed state, the water molecule gap is larger than the liquid water molecule gap under the atmospheric pressure and smaller than the gas water molecule gap, the heat transfer depends on the interaction of microscopic water molecules or water molecule groups, the heat transfer effect is optimal at this moment, the water in the tube cavity starts to flow naturally and rapidly (the arrow direction in the drawing) due to the fact that the temperature difference between the heated part and the non-heated part provides natural driving force, and the water at lower temperature and the water at the heated part continuously generate the temperature difference due to the fact that the heated part is continuously heated, so that the water in the tube cavity flows in a rapid circulation mode, the heat transfer can be realized by heating at any point, and the antigravity can be realized.
The heat collector collects heat of the heating element needing heat dissipation, and heats the non-phase-change superconducting heat transfer working medium in the system, the system is started by the continuous heating system, the natural circulation of the working medium in the system rapidly conducts the heat to the heat exchange unit to change out the heat, the low-temperature non-phase-change superconducting heat transfer working medium after heat exchange continuously circulates in the system to form the whole heat dissipation system, so that a proper working temperature is provided for the device, the device is enabled to be at the same temperature due to excellent temperature uniformity of the superconducting internal circulation, the working state is balanced, and the service life is prolonged. The heat collector is in contact with the heating element needing heat dissipation for heat exchange, so that heat collection is performed, and a channel communicated with the non-phase-change heat transfer pipeline is arranged in the heat collector.
Similarly, when other types of non-phase-change superconducting heat transfer working mediums are used according to specific use environments, the overflow method is also used for filling the working mediums, and high heat conductivity, uniform temperature and antigravity are realized by virtue of microscopic molecular heat transfer.
Example 2
As shown in fig. 4, this embodiment is different from embodiment 1 in that: the non-phase-change superconducting internal circulation heat dissipation system further comprises a circulation pump 5 for driving the non-phase-change superconducting heat transfer working medium to flow, and the circulation pump 5 is arranged in the non-phase-change heat transfer pipeline 1.
The circulating pump 5 can do work when the environmental pressure is higher than the atmospheric pressure, as shown in fig. 5, the circulating pump 5 consists of an impeller 6, a blade window type fixing frame 7, a motor 8 and a shell 9, and the circulating pump 5 meets the compatibility requirement of non-phase-change superconducting heat transfer working media. The circulating pump has the following characteristics:
the casing of the circulating pump plays a role in bearing pressure;
the inlet and outlet of the circulating pump shell are designed to ensure that the working medium full cavity in the shell enables the pressure in the shell to be the same (namely the internal pressure bearing is the same) when the circulating pump runs, so that the circulating pump can still safely apply work even when the environmental pressure is higher than the atmospheric pressure. For example, an inlet is formed in the casing of the circulating pump to suck the working medium, and the motor drives the impeller to rotate so that the working medium enters and fills the casing, and then the working medium is pushed out of the casing (namely, the working medium is pushed out by overflowing after the working medium fills the inner cavity of the casing), so that the working medium in the casing is fully filled in the casing during operation, and the pressure in the casing is the same everywhere, so that the operation of the circulating pump is not influenced by the environmental pressure. The specific design method of the shell is based on different use positions, and different inlet and outlet positions and angles can be set on the principle of ensuring full liquid running in the circulating pump shell.
The energy consumed in the working process of the circulating pump is mainly used for resisting the flowing friction force and the flowing resistance of working media, and the pressure in the circulating pump shell is the same, so that the blocking force is smaller when the impeller rotates, and the consumed energy is smaller.
The arrangement of the circulating pump enables the pipeline to further push the liquid working medium to circularly move along the driving direction (A direction in fig. 5) of the circulating pump at a high speed on the basis of the original natural circulation, so that the heat exchange efficiency, the uniform temperature speed and the heat flow density are improved, and the antigravity conduction can be realized.
The working principle of the invention is as follows:
the system is checked for leakage prevention, the system is filled with working medium after no leakage, the filling method is the same as the filling method in the embodiment 1, an overflow method is still adopted, the whole system is filled with the working medium which is filled to the non-phase-change superconducting heat transfer medium when the device is placed still, then the system is heated to the use temperature (or design temperature), the working medium in the system overflows slightly due to thermal expansion, the filling amount in the system is far greater than the filling amount of the phase-change heat pipe at the moment, the system is packaged, and a rare vacuum area 10 exists above a pipeline after the system is cooled to the ambient temperature after the filling is completed, as shown in fig. 6, and the overflow filling method can ensure good vacuum degree.
As shown in fig. 7, when the system works, the heat collector collects heat of the heating element needing heat dissipation, the circulating pump accelerates the internal circulation of the non-phase-change superconducting heat transfer working medium (in the direction of arrow in the figure), the heat is quickly conducted to the heat exchange unit to change out the heat, the low-temperature non-phase-change superconducting heat transfer working medium after heat exchange continuously circulates in the system to form the whole heat dissipation system, so that a proper working temperature is provided for the device, the device is uniform in temperature due to excellent uniform temperature property of the superconducting internal circulation, the working state is balanced, and the service life is prolonged.
The same principle as that of embodiment 1 is that, as shown in fig. 6, in the state before working, a part of the working fluid is in a rare vacuum area, and the other part of the working fluid is in a full liquid state, when the non-phase change heat transfer pipeline is heated and started, the working fluid is in the working state of fig. 7, the rare vacuum area is immediately disappeared, and the working fluid is in a gas-liquid mixed state, but the circulating pump drives the heating fluid to circulate, so that the heat transfer effect is more obvious, and the ultra-rapid heat exchange is greatly improved. The automatic and passive heat transfer mode is adopted, so that the device has stronger environmental adaptability, structural adaptability and space adaptability, can be started by making the device into different structural shapes or being used for realizing small temperature difference between a gravitational field and a non-gravitational field, and has controllable heat transfer direction, controllable working medium circulation direction and controllable power.
Embodiments of the present invention are not limited thereto, and according to the above-described aspects of the present invention, there are other embodiments of the non-phase-change superconducting heat transfer medium, the structure of the heat collector, the heat exchanging form of the heat exchanging unit, etc. according to the general knowledge and conventional means in the art, without departing from the basic technical ideas of the present invention.
