In this embodiment, the shell assembly 100 comprises a main storage rack 101, which is a cylindrical tubular structure, one end is sealed, and the other end is left open. An installation end piece 102 is arranged in the main storage rack 101. A water inlet pipe 103 and a water outlet pipe 104 are arranged on the side wall of the main storage rack 101. The water inlet pipe 103 and the water outlet pipe 104 are arranged at two positions of the main storage rack 101. In use, the main storage rack 101 is in a horizontal state, and at this time, the water inlet pipe 103 is located at the upper end, and the water outlet pipe 104 is located at the lower end.

[0031] Preferably, flanges are arranged on the water inlet pipe 103 and the water outlet pipe 104 to facilitate connection with external pipelines.

[0032] Further, the utility model also comprises a heat exchange assembly 200. In this embodiment, the heat exchange assembly 200 comprises a heat exchange pipe 201 arranged in the main storage rack 101, a connecting head 202 arranged on the heat exchange pipe 201, and a connecting line 203 arranged on the connecting head 202. Liquid enters the main storage rack 101 from the water inlet pipe 103, then passes through the heat exchange pipes 201, and flows out from the water outlet pipe 104 after heat exchange. The heat exchange pipe 201 can be an electric heating pipe heat exchange pipe or a supercooling pipe, so that the operator can select different heat exchange modes according to needs.

[0033] Preferably, the connecting line 203 is a heating circuit, which is used to heat the heat exchange pipe 201 to make the heat exchange pipe 201 warm up. The connecting line 203 is arranged on the outer side close to the main storage rack 101, and the heat exchange pipe 201 is arranged at the rear end of the connecting line 203, so that the end part and the main part of the heat exchange pipe 201 can be separated. A plurality of heat exchange pipes 201 are arranged at the rear end of the connecting line 203 and closely arranged in a certain order. The connecting head 202 on each heat exchange pipe 201 is connected to the connecting head 202 on the remaining heat exchange pipes 201 through the connecting line 203.

[0034] Further, the electric control module is electrically connected to the heating resistance wire, and controls the heating resistance wire to generate heat. The heating resistance wire is embedded in the wall of the heat exchange pipe 201. The electric control module is also connected in series with the connecting line 203, so as to control the working of the heating resistance wire on all the heat exchange pipes 201.

[0035] In the embodiment, the mounting end piece 102 comprises a plurality of extension sleeves 102a arranged on the main storage rack 101 and a storage space 102b formed between the extension sleeves 102a and the main storage rack 101. The extension sleeves 102a are matched with the main storage rack 101. A baffle 102c is arranged in the extension sleeve 102a. A connecting hole for connecting the heat exchange pipe 201 is arranged on the baffle 102c. The baffle 102c divides the space in the main storage rack 101 into the storage space 102b and an isolation cavity. The isolation cavity is not communicated with the storage space 102b. In the embodiment, the storage space 102b is divided into two.

[0036] Preferably, the heat exchange pipe 201 is in a U shape, and the two ends of the heat exchange pipe 201 extend into the isolation cavity. In the embodiment, 18 heat exchange pipes 201 are arranged in the main storage rack 101 in a circumferential array, and form four layers. Eight heat exchange pipes 201 in the first layer are arranged around the inner wall of the main storage rack 101. Four heat exchange pipes 201 in the second layer are arranged around the inner side of the first layer. Four heat exchange pipes 201 in the third layer are arranged around the inner side of the second layer. Two heat exchange pipes in the fourth layer are arranged in the center. The heat exchange pipes 201 in each layer and between each heat exchange pipe 201 are provided with gaps for liquid flow. The arrangement enables the water to fully pass through each heat exchange pipe 201, so that better heat exchange can be achieved.

[0037] Further, a plurality of guide plates 400 are arranged in the storage space 102b. The guide plates 400 are provided with mounting holes for mounting the heat exchange pipes 201. The side wall of the guide plates 400 is provided with a gap with the inner wall of the main storage rack 101. The gaps form a liquid flow path.

[0038] A cover plate 401 is arranged on the extension sleeve 102a. The extension sleeve 102a and the cover plate 401 are connected by bolts. A sealing gasket is arranged between the extension sleeve 102a and the cover plate 401.

[0039] In the embodiment, the connecting head 202 comprises a circulating head 204 connected with the heat exchange pipe 201, a connecting frame body 202b detachably connected with the circulating head 204, a circulating plate 202c arranged on the heat exchange pipe 201, and a liquid outlet head 202d arranged on the heat exchange pipe 201. In the embodiment, the circulating head 204 comprises a circulating rotating head 204a connected with the circulating plate 202c, and a plurality of side plates 204b arranged on the circulating rotating head 204a.

[0040] Further, a linkage member 300 is arranged between the circulating rotating head 204a and the circulating plate 202c, and the linkage member 300 controls whether the circulating rotating head 204a and the circulating plate 202c are communicated. A pipe interface is arranged on the circulating plate 202c.

[0041] As preferred, the linkage member 300 comprises a fixed ring 301 arranged on the circulating plate 202c, an arc-shaped plate 302 rotatably connected with the fixed ring 301, a rotating ring 303 rotatably connected with the circulating rotating head 204a, a rotating rod 304 hingedly connected with the rotating ring 303, and an external gear arranged on the outer sidewall of the rotating ring 303. The rotating rod 304 is hingedly connected with the arc-shaped plate 302, and the hinging position of the rotating rod 304 is away from the hinging position of the arc-shaped plate 302 and the fixed ring 301. A clamping strip matched with the external gear is arranged on the upper surface of the circulating plate 202c, and the clamping strip has a certain flexibility.

[0042] Operation process: when the heat exchange is performed, the operator opens the cover plate 401 at the end of the extension sleeve 102a according to the need, rotates the circulating rotating head 204a, and the rotation of the circulating rotating head 204a drives the rotating ring 303 to rotate. After the rotating ring 303 rotates, the rotation of the arc-shaped plate 302 is pulled through the rotating rod 304, so that the plurality of arc-shaped plates 302 change from the mutual opening state to the gathering state, thereby closing the opening on the connecting frame body 202b. At this time, the operator controls the heating element through the power supply to heat the heat exchange pipe 201, and then pours water from the water inlet pipe 103 into the main storage rack 101 to perform the heat exchange.

[0043] Then, when the heat exchange pipe 201 is not required to be in the heating mode, the operator reversely rotates the circulating rotating head 204a to drive the rotating ring 303 to reversely rotate, thereby further driving the arc-shaped plate 302 to move from the mutual gathering state to the mutual dispersion state. At this time, the external pipeline is inserted into the circulating rotating head 204a, and then the external liquid is introduced. Then, water is poured from the water inlet pipe 103 into the main storage rack 101 to perform the heat exchange action of the tube and shell of the two fluids.

[0044] The heat exchanger has a compact internal heat exchange pipe structure, a small overall structure, and can perform two heat dissipation modes, and has more adaptability and functionality.
