Technical Field

[0002] Traditional radiators usually use water cooling for heat dissipation, which requires a water pump to drive the water flow, and a fan to accelerate air circulation for heat dissipation. The entire structure adds auxiliary equipment such as water pumps and fans, which makes the system components numerous, the equipment occupies a large space, the process is more complicated, and the failure rate and maintenance cost of the cooling system are high. In addition, there is a risk of water leakage when using water cooling for heat dissipation. Moreover, the long-term reciprocating motion of the heat transfer liquid causes friction and wear inside the micro-water channels and radiator of the radiator, resulting in a decrease in heat dissipation performance and a shortened warranty period. Therefore, a simpler, more efficient and safer heat dissipation solution is needed. Utility Model Content

DETAILED DESCRIPTION

[0030] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0031] like Figure 1 to Figure 2 As shown, a turbine cooling radiator described in the utility model includes a high-pressure gas source 1, a vortex refrigeration device 2 and a radiator body 3, wherein the high-pressure gas source 1 is an air compressor, and the vortex refrigeration device 2 includes a vortex chamber 21, a high-pressure gas inlet end 22 respectively connected to the outlet end of the high-pressure gas source 1, and a cold air output end 23 and a hot air output end 24.

[0032] The cold air output end 23 and the hot air output end 24 are located on the same straight line. A control valve 25 is provided at the air outlet of the hot air output end 24 , and the temperature and air volume of the cold air are adjusted by the control valve 25 .

[0033] In this embodiment, Figure 3 The radiator body 3 includes an upper cover plate 31 and a lower base plate 32, the upper cover plate 31 and the lower base plate 32 are fixed by screws, and the opposite end surfaces of the upper cover plate 31 and the lower base plate 32 are respectively recessed inward through the end surfaces to form a closed heat dissipation chamber 33 and an air inlet 34 and an air outlet 35 respectively connected to the heat dissipation chamber 33; the air inlet 34 is connected to the cold air output end 23; the air outlet 35 is connected to the outside air.

[0034] Furthermore, the air inlet 34 and the air outlet 35 have the same air flow direction. In order to achieve a better circulation effect of cold air, the air inlet 34 and the air outlet 35 are located on the same straight line.

[0035] Specifically, the lower base plate 32 is a planar heat dissipation copper plate structure, the lower end surface of the heat dissipation copper plate structure is in direct contact with the heat source, and the upper end surface of the heat dissipation copper plate structure is recessed inward to form a shovel groove 321, and a micro-airway structure 322 is arranged in the shovel groove 321. The arrangement of the shovel groove 321 makes the thickness of the heat dissipation copper plate structure thinner than the original one, which can improve the heat conduction effect and accelerate the heat conduction rate.

[0036] Furthermore, if Figure 4 The micro-airway structure 322 includes a plurality of groups of micro-airways 323 separated by a plurality of groups of equidistantly arranged heat dissipation fins, and the arrangement direction of the heat dissipation fins is perpendicular to the air flow direction of the air inlet 34 and the air outlet 35. After the cold air passes through the air inlet 34 and hits the micro-airway structure 322 of the heat dissipation copper plate structure, it is diverted and guided to flow in each group of micro-airways 323. The arrangement direction of the heat dissipation fins is more convenient for guiding the cold air, increasing the activity rate of the cold air, so as to achieve sufficient and rapid heat exchange and improve the heat exchange efficiency.

[0037] Furthermore, the lower end surface of the upper cover plate 31 is provided with a receiving groove 311 whose end surface is recessed inwardly, and the heat dissipation chamber 33 is formed by combining the shovel groove 321 and the receiving groove 311, and becomes a receiving space for the micro airway structure 322. Figure 5 .

[0038] In this embodiment, the air inlet 34 is provided with a hose, and the cold air output end 23 is connected to the air inlet 34 through the hose.

[0039] The working principle of the radiator body 3 is as follows: the heat dissipation copper plate structure absorbs the heat conducted from the heat source and conducts it to the micro-airway structure 322. Since the micro-airway structure 322 is located in the heat dissipation chamber 33, the contact area with the circulating cold air is further increased, which is conducive to faster and more complete removal of heat, and each group of micro-airways 323 becomes a heat exchange channel of the radiator body 3.

[0040] The working principle of the vortex refrigeration device 2 is as follows: the high-pressure gas source 1 works, expands and accelerates the compressed air in the nozzle at the inlet end, and sprays it to the vortex chamber 21 from the tangential direction to form a free vortex, which flows to the hot air output end 24, and part of the airflow flows out through the control valve 25. After the remaining airflow is blocked, it rotates in the same direction in the inner circle of the original airflow and flows to the cold air output end 23 at the same speed. Since the rotation angular velocity of the free vortex is greater as it approaches the center, the angular velocities are different, and friction is generated between the layers of the free vortex. The airflow angular velocity of the central part is the largest, and the energy is transferred to the airflow with a smaller angular velocity in the outer layer through friction. The airflow in the central part loses energy, has low kinetic energy, reduces speed, and reduces temperature, and obtains the cold airflow required for heat dissipation of the radiator body 3. The airflow in the outer layer gains momentum, increases kinetic energy, and rubs against the inner wall of the vortex refrigeration device 2 at the same time, converting part of the kinetic energy into heat energy, which is led out from the hot air output end 24 through the control valve 25 to form a hot airflow to complete the heat exchange between the two airflows.

[0041] When in use, the cold air generated by the vortex refrigeration device 2 enters the heat dissipation chamber 33 along the air inlet 34 and flows in each group of micro-airways 323, thereby absorbing the heat dissipated by the heat source, and the cold air becomes hot air and is discharged to the external environment from the air outlet 35.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
