Technical Field

[0001] The utility model relates to the technical field of heat exchange equipment, in particular to a heat conversion device for a gas preparation system. Background Art

[0002] In the existing gas heat exchange equipment, the heat exchange tube is a cylindrical pipe, which has the advantages of simple structure and easy installation. However, under the same volume, the surface area of ​​the cylindrical pipe is smaller than the surface of the rectangular parallelepiped, so the structure of the existing heat exchange tube needs to be improved; in addition, due to the problem of workmanship accuracy, the heat exchange tube is slightly longer or shorter, which will affect the actual installation of the heat exchange tube. In view of the above technical problems, this application proposes a new heat conversion solution to solve the above problems. Utility Model Content

[0003] In order to solve the above technical problems, the utility model discloses a heat conversion device for a gas preparation system. In this solution, the heat exchange tube is designed as a corrugated tube, which effectively increases the surface area of ​​the tube, thereby improving the heat conversion efficiency.

[0004] Specifically, the utility model discloses a heat conversion device for a gas preparation system, comprising:

[0005] A tank body, wherein the tank body has a cavity, wherein the cavity is provided with a refrigerant converging cavity, a hot air flow cavity and a refrigerant inflow cavity which are isolated from each other, wherein the tank body is provided with an air inlet and an air outlet which are connected to the hot air flow cavity, and wherein the tank body is provided with a refrigerant inlet which is connected to the refrigerant inflow cavity;

[0006] A guide plate, wherein the guide plate is arranged in the hot air flow cavity, and the air inlet and the air outlet are respectively located on two sides of the guide plate;

[0007] A corrugated heat exchange tube, one end of which is connected to the refrigerant inflow cavity, and the other end of which is connected to the refrigerant confluence cavity.

[0008] The improvement of this solution is that the heat exchange tubes in the prior art usually adopt circular tubes, which have a relatively small surface area under the same volume. In view of this, this solution designs the heat exchange tubes into corrugated tubes, which effectively increases the surface area of ​​the pipes, thereby improving the heat conversion efficiency.

[0009] Preferably, a conduit is further provided in the tank body, the input end of the conduit is communicated with the refrigerant conduit cavity, and the output end of the conduit passes through the mounting hole on the guide and extends to the outside of the tank body.

[0011] Furthermore, the output end of the manifold passes through the refrigerant into the cavity.

[0012] Preferably, the portion of the manifold located in the refrigerant inflow cavity is coated with a heat insulation layer.

[0013] The technical effect of this solution is to avoid heat loss at the end of the manifold and to improve the heat exchange efficiency of the device.

[0014] Furthermore, the axis of the manifold coincides with the axis of the tank body.

[0015] Preferably, the guide plate is a spiral plate.

[0016] The technical effect of this solution is that it enables the gas to move along the spiral direction of the guide plate, which on the one hand increases the movement range of the gas, and on the other hand continuously changes the contact angle between the gas and the heat exchange tube, thereby improving the heat exchange efficiency of the device.

[0026] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0027] Example 1

[0028] This embodiment discloses a heat conversion device for a gas preparation system, such as Figures 1 to 3 As shown, there is a tank body 11, in which there is a cavity, two closing plates are fixed in the cavity, and the cavity is used to divide the cavity into three areas, wherein the area between the two closing plates is a hot gas flow cavity 13, one side area of ​​the hot gas flow cavity 13 is a refrigerant confluence cavity 12, and the other side area of ​​the hot gas flow cavity 13 is a refrigerant inflow cavity 14; both ends of the tank body 11 are respectively provided with an air inlet 15 and an air outlet 16 connected to the hot gas flow cavity 13. A spiral plate is provided in the hot gas flow cavity 13, and the spiral plate is used to make the gas in the cavity flow in a spiral manner, and to increase the travel of the gas in the cavity.

[0029] The tank body 11 is also provided with a heat exchange tube and a manifold 20, one end of the heat exchange tube is connected to the refrigerant inflow cavity 14, and the other end of the heat exchange tube passes through the guide hole on the spiral plate and is connected to the refrigerant manifold cavity 12; the axis of the manifold 20 coincides with the axis of the tank body 11, the input end of the manifold 20 is connected to the refrigerant manifold cavity 12, and the output end of the manifold 20 passes through the mounting hole on the spiral plate and extends to the outside of the tank body 11. There are multiple heat exchange tubes, but only one manifold 20.

[0030] During operation, the gas flows into the hot gas flow cavity 13 through the air inlet 15, and moves along the spiral direction of the spiral plate, and finally flows out from the air outlet 16. At the same time, the cooling water flows into the refrigerant inflow cavity 14, and flows into the refrigerant confluence cavity 12 through the heat exchange pipe, and realizes the heat exchange between the cold water and the hot air; finally, the water in the refrigerant confluence cavity 12 is discharged through the confluence pipe 20.

[0031] As an implementation of this embodiment, the output end of the manifold 20 passes through the refrigerant inflow cavity 14 and extends to the outside of the tank body 11 , wherein the portion of the manifold 20 located in the refrigerant inflow cavity 14 is coated with a heat insulation layer 21 .

[0032] Example 2

[0033] In the prior art, heat exchange tubes are usually round tubes. Since the area of ​​a cylindrical tube is smaller than that of a tube of other shapes under the same volume, a round heat exchange tube is actually not conducive to heat exchange. Based on Example 1, the heat exchange tube in this scheme can be in the shape of a triangular prism or a quadrangular prism; in addition, the heat exchange tube can also be a corrugated tube, such as Figure 4As shown; the heat exchange tubes in the prior art all use rigid tubes, while the present embodiment uses corrugated tubes. On the one hand, the length of the corrugated tubes is retractable, which can offset the installation error caused by the excessively long or short length of the pipe; on the other hand, while the gas in the hot gas flow cavity 13 flows, the contact area with the heat exchange tube can be increased, thereby improving the heat exchange efficiency of the device.

[0034] For ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the utility model, which all fall within the protection scope of the utility model.
