The technical solution of the present invention and how to solve the above technical problems will be described in detail with specific examples.

The embodiment of the first aspect of the present application provides a purified gas circulation cooling device, as shown in fig. 1, comprising a preheater 100, a first siphon 200, a second siphon 300 and a radiator 400; a first through hole cavity 110 is arranged on the preheater 100, and a second through hole cavity is arranged on the radiator 400; the outlet of the first siphon 200 and the inlet of the second siphon 300 are both arranged on the pre-heater 100, the outlet of the first siphon 200 is above the inlet of the second siphon 300; the second siphon 300 is connected to the first siphon 200 after passing through the radiator 400, and the pre-heater 100, the first siphon 200, and the second siphon 300 are all provided with a heat conducting agent.

The first through cavity 110 of the preheater 100 is used for installing the components to be heated, and the first through cavity 110 is a through hole structure formed in the sealed preheater 100 and does not affect the sealing performance of the preheater 100. The same is true for the second through bore. The heat conducting agent is added into the pre-heater 100 in a sufficient amount, and under the action of the siphon effect, the heat conducting agent enters the second siphon pipe 300 from the inlet of the second siphon pipe 300 and flows into the heat sink 400, and the heat sink 400 heats the heat conducting agent in the second siphon pipe 300 sufficiently, so that the heat conducting agent is vaporized and enters the first siphon pipe 200. The gaseous heat-conducting agent reaches the pre-heater 100 through the first siphon 200, the temperature is conducted to the components in the first through-hole cavity 110, the heat-conducting agent is liquefied and enters the second siphon 300, and the heat in the radiator 400 is conveyed into the pre-heater 100 in a reciprocating mode. Optionally, the heat sink 400 is a finned heat sink 400.

In the radiator 400, the liquid heat-conducting agent is gasified, so that the pressure at the joint of the first siphon pipe 200 and the second siphon pipe 300 is increased, and in the pre-heater 100, the gaseous heat-conducting agent is liquefied again, so that the gas pressure at the outlet of the first siphon pipe 200 is reduced. The pressure difference between the first siphon pipe 200 and the second siphon pipe 300 causes the heat-conducting agent to enter the radiator 400 from the siphon pipe 300, and the heat-conducting agent circulates in the purified gas circulation cooling device in accordance with the siphon phenomenon in the first siphon pipe 200, the second siphon pipe 300, the pre-heater 100 and the radiator 400.

Optionally, the second siphon tube 300 is distributed in a serpentine shape and reciprocally disposed through the radiator 400. In order to make the heat sink 400 contact with the second siphon tube 300 as much as possible to sufficiently absorb the heat in the heat sink 400, the length of the second siphon tube 300 in the heat sink 400 is increased in a serpentine-shaped distribution state.

Optionally, in one implementation of the utility model, the thermal conductor is diethyl ether. The boiling point of the ether is 34.5 ℃, and the ether will be in a gaseous state after exceeding the boiling point, and will ascend into the preheater 100 from the position of the radiator 400 along the second siphon tube 300 and the first siphon tube 200. Cooled in the preheater 100 to form liquid ether, which accumulates in the inner cavity of the preheater 100.

Alternatively, in an embodiment of the present application, as shown in fig. 2, the outlet of the first siphon tube 200 is close to the top end surface of the inner cavity of the preheater 100, and the inlet of the second siphon tube 300 is close to the bottom end surface of the inner cavity of the preheater 100. The gaseous heat-conducting agent is above the inner cavity of the preheater 100, the liquid heat-conducting agent is below the inner cavity, and the gaseous heat-conducting agent above the gaseous heat-conducting agent can press the liquid heat-conducting agent into the second siphon tube 300. By virtue of the siphon effect, the liquid heat-conducting agent can easily enter the second siphon tube 300 and flow downward to the second siphon tube 300 at the position of the heat sink 400.

The embodiment of the second aspect of the present application provides a heating type gas purifier, as shown in fig. 1 and 2, comprising a gas purifier 10 with a heating device 20 and a purified gas circulation cooling device according to any one of the first aspect of the present application; the inlet pipe 11 of the gas purifier 10 is inserted into the preheater 100 through the first through-hole 110, and the outlet pipe 12 of the gas purifier 10 is inserted into the radiator 400 through the second through-hole. The gas purifier 10 has a gas inlet pipe 11 and a gas outlet pipe 12, the gas inlet pipe 11 is arranged on the preheater 100 through the first through hole 110, and the shape and the size of the two are matched with each other, so that the preheater 100 and the gas inlet pipe 11 form heat conduction as much as possible. Similarly, the outlet tube 12 should also match the second through bore. The temperature of the gas to be purified in a cooling state is increased after being preheated by the preheater 100, the gas enters the gas purifier 10 and is heated by the heating device 20, the gas with high temperature after being purified is obtained, and the temperature of the discharged gas can be greatly reduced after the heat is transferred to the heat conducting agent.

In addition, the gas to be purified entering from the gas inlet pipe 11 is compressed gas with a certain pressure, and the temperature of the gas is low, so that the heat-conducting agent in the preheater 100 can be liquefied from a gas state at an accelerated speed, and a liquid heat-conducting agent is formed in the preheater 100. Accordingly, after being heated by the heating device 20, the purified gas flowing out of the gas outlet pipe 12 has a high temperature, and the heat conducting agent is rapidly gasified, enters the first siphon pipe 200, flows into the pre-heater 100 through the outlet of the first siphon pipe 200, and circulates.

The purified gas circulating cooling device and the heating type gas purifier provided by the utility model combine the purified gas circulating cooling device with the heat dissipation and heat transmission functions with the gas purifier 10 through the first through hole cavity 110 and the second through hole cavity which are matched and connected with the gas purifier 10, preheat the gas to be purified entering the gas purifier 10 by utilizing the heat generated by the heating type gas purifier, promote the circulation of a heat conducting agent by utilizing the siphon principle and the pressure of the gas, and simultaneously solve the two problems of gas preheating and gas output cooling in the heating type gas purifier.

Optionally, in another implementation manner of the embodiment of the second aspect, a plurality of heat dissipation fins are disposed in parallel in the inner cavity of the pre-heater 100. The heat can be contacted with the outer wall of the first through hole cavity 110 with a larger contact area by arranging the heat dissipation fins, so that more heat can be transferred into the first through hole cavity 110.

Alternatively, in other implementations of the second aspect embodiment, as shown in fig. 3, the outlet tube 12 is in a serpentine shape and reciprocates through the heat sink 400; the outer wall of the first through hole 110 of the inner cavity of the pre-heater 100 is provided with a plurality of hollow heat dissipation plates 120, and the inner cavity of the hollow heat dissipation plates 120 is communicated with the first through hole 110. The outlet pipe 12 is distributed in a serpentine shape and reciprocates through the radiator 400, so that the outlet pipe 12 can sufficiently radiate heat to the radiator 400. The hollow heat dissipation plate 120 is disposed on the outer wall of the first through hole 110 of the inner cavity of the preheater 100, which can also increase the contact area and contact time of the gaseous heat conducting agent with the preheater 100, thereby more fully transferring heat.
