In this embodiment, heat exchanger casing 1 includes ring flange and lower ring flange, go up the ring flange set up in heat exchanger casing 1 the gas passing end, lower ring flange set up in heat exchanger casing 1 insert the end, go up the ring flange with the metal material processing is used to lower ring flange the cladding has one deck metal casing between the ring flange with the lower ring flange, so set up, heat radiating effect of heat exchanger casing 1 is better, just each part of heat exchanger casing 1 is the standard component commonly used, need not extra die sinking, and the cost of manufacture is lower, and when the damage appears in the part, the part is more easy to change.
Further, in this embodiment, as shown in fig. 1, the air outlet channel 11 is disposed through the insertion end and the air passing end along the length direction of the heat exchanger shell 1, and the air outlet channel 11 includes two air outlets 111 and an air outlet pipe 112, where the two air outlets 111 are separately disposed in the middle of the insertion end and the air passing end, and the air outlet pipe 112 is used to connect the air outlets 111 of the insertion end and the air passing end; the air inlet channel 12 is disposed through the insertion end and the air passing end along the length direction of the heat exchanger shell 1, and the air inlet channel 12 includes two air inlets 121 and an air inlet pipe 122, each air inlet 121 is disposed on a circumferential side of each air outlet 111, and the air inlet pipe 122 is configured to connect the insertion end and each air inlet 121 of the air passing end. The material of intake pipe 122 is the metal material, because the heat conduction effect of metal material is better for the hot air is when passing through intake pipe 122, can release more heat, and the radiating effect is better, the metal material also can be adopted to gas storehouse 2, with this further radiating effect that promotes. In addition, in the present embodiment, the connection manner between the air outlet pipe 112 and the air outlet 111 may be adhesive or welding, or may be threaded connection, and similarly, the connection manner between the air inlet pipe 122 and the air inlet 121 may be adhesive, welding or threaded connection, including but not limited to the above connection manner, and the actual connection manner may be selected according to practical situations.

After the plurality of air inlets 121 and the air inlet pipes 122 are provided, when the amount of the inputted hot air is constant, the flow rate of the hot air in each of the air inlet pipes 122 is reduced, so that the hot air has more time to dissipate heat; when the flow rate of the inputted hot air is not changed, the amount of the inputted hot air per unit time is multiplied so that the amount of the outputted cold air is more, thereby improving the heat exchange efficiency of the buried air heat exchanger 100.
In order to make the air flow smooth, the flow rate of the hot air input should be equal to or less than the flow rate of the cold air input, that is, the amount of the hot air input per unit time is equal to or less than the amount of the cold air output, so in this embodiment, as shown in fig. 2, the cross-sectional area of the air outlet 111 is S1, and the total cross-sectional area of the air inlets 121 is S2, S1 is equal to or greater than S2. To achieve better effect, the amount of hot air input per unit time should be made approximately equal to the amount of cold air output, that is, the cross-sectional area of the air outlet 111 is approximately equal to the total cross-sectional area of the plurality of air inlets 121, s1≡s2.
When no hot air is input into the air inlet channels 12, the cold air in the air bin 2 may flow back to the air inlet channels 12, resulting in a decrease in the cold air output from the air outlet channels 11, so in this embodiment, as shown in fig. 2, an air tap 123 is mounted at one end of each air inlet pipe 122 near the insertion end, and the air tap 123 is bent to prevent the air in the air bin 2 from flowing back to the air inlet channels 12. The air tap 123 may also be made of metal, and the heat conduction effect of the metal makes the hot air in the air inlet pipe 122 release more heat.
In order to further improve the heat dissipation effect of the air bin 2, in this embodiment, as shown in fig. 2, each air nozzle 123 is arranged along a tangential direction of the air bin 2, so that air entering the air bin 2 forms a rotating air flow to help heat dissipation. So set up, when getting into treat that the heat dissipation air of gas storehouse 2 forms rotatory air current, can accelerate treat the heat dissipation air with the heat exchange of gas storehouse 2 inner wall, in addition gas storehouse 2 adopts the better metal material of heat conductivility to improved the efficiency of heat exchange greatly, made the radiating effect better.
Since the longer the hot air stays in the air inlet pipe 122, the more heat is released, and the longer the air inlet pipe 122 needs to be in order to improve the heat dissipation effect, in this embodiment, the air inlet pipe 122 is attached to the outer side wall of the air outlet pipe 112, and is spirally extended along the length direction of the heat exchanger housing 1 from the air passing end to the inserting end.
When the buried air heat exchanger 100 is used for a long time, the temperature of the air inlet pipe 122 is higher, so that the hot air cannot release more heat, and the heat dissipation performance of the air inlet pipe 122 is reduced, in order to maintain the heat dissipation performance of the air inlet pipe 122, in this embodiment, a cooling cavity is provided in the heat exchanger housing 1, and a cooling liquid is provided in the cooling cavity to cool the air to be dissipated in the air inlet pipe 122. The cooling liquid can take away the heat of the air inlet pipe 122, so that the air inlet pipe 122 is kept at a lower temperature, and further the air inlet pipe 122 maintains a better heat dissipation performance. Simultaneously, the cooling liquid with lower temperature is injected into the cooling cavity, so that the overall heat dissipation effect can be further improved.
If the distance between the air outlet pipe 112 and the air inlet pipe 122 is too short, the heat released by the hot air in the air inlet pipe 122 is absorbed by the air outlet pipe 112, so as to avoid thermal short circuit formed by heat exchange between the air outlet pipe 112 and the air inlet pipe 122, in this embodiment, the air outlet pipe 112 is made of plastic material, and the outer side wall of the air outlet pipe 112 is provided with a heat insulation material. So configured, heat released by the hot air in the air inlet duct 122 is prevented from being absorbed by the air outlet duct 112, resulting in an increase in the temperature of the cold air in the air outlet duct 112.
In order to make it easier to insert the buried air radiator directly into the ground, in the present embodiment, as shown in fig. 1, the air tanks 2 are inclined from the circumferential side of one end near the insertion end toward the middle of the other end so that the air tanks 2 are arranged in a tapered shape.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the specification and drawings of the present invention or direct/indirect application in other related technical fields are included in the scope of the present invention.
