[0020] The present invention will be further described in detail below with reference to the drawings.

[0021] As Figure 1-3As shown, the device includes a hollow water chamber 1, which is generally in the shape of a horizontally placed cylinder with openings at both ends (referred to as the front and rear ends), and an inlet pipe 2 and an outlet pipe 3 are also connected to the circumferential top of the water chamber 1.

[0022] The interior of the water chamber 1 is divided into a first chamber 4, a second chamber 5, and a third chamber 6 by an inverted T-shaped partition plate 11, and the cross-sectional size of the third chamber 6 is equivalent to the sum of the first chamber 4 and the second chamber 5. Among them, the first chamber 4 and the second chamber 5 are both located above and are respectively connected to the inlet pipe 2 and the outlet pipe 3, while the third chamber 6 is located below.

[0023] Flange rings 7 are provided at both openings at the front and rear ends of the water chamber 1, and the flange ring 7 at the front end of the water chamber 1 is movably connected to a flange blind cover 9 through a hinge 8. The flange blind cover 9 is fixed by other methods after closing, and the flange ring 7 at the front end of the water chamber 1 is used to connect to the heat exchanger 10.

[0024] Preferably, when the two flange rings 7 are respectively connected to the flange blind cover 9 and the heat exchanger 10, they are respectively sealed by two sealing gaskets 12.

[0025] As Figure 4 shown, the heat exchanger 10 includes a heat exchange channel 13 and a head 14. Among them, the heat exchange channel 13 is divided into multiple pipes and is respectively connected to the first chamber 4, the second chamber 5, and the third chamber 6. At the head 14, the pipes connecting the first chamber 4 and the second chamber 5 are respectively and individually connected to the pipes connecting the third chamber 6, so that the first chamber 4 and the second chamber 5 are respectively connected to the third chamber 6 through the heat exchanger 10.

[0026] When the device is in use, the water chamber 1 is connected to the heat exchanger 10, and the flange blind cover 9 is closed. The water to be heat-exchanged is introduced into the water chamber 1 from the inlet pipe. The water will sequentially pass through the first chamber 4, the heat exchange channel 13, the head 14, the heat exchange channel 13, the third chamber 6, the heat exchange channel 13, the head 14, the heat exchange channel 13, the second chamber 5, and finally flow out from the outlet pipe, thus completing the heat exchange.

[0027] As Figure 5 shown, when it is necessary to clean the water chamber 1 and the heat exchanger 10, first remove the fixation between the flange blind cover 9 and the water chamber 1, remove the sealing gasket 12, and then rotate and open the flange blind cover 9 through the hinge 8, and then the water chamber 1 and the heat exchanger 10 can be cleaned. In this process, it is not necessary to disassemble the water chamber 1, nor is it necessary to use a lifting device, thereby reducing the operation difficulty and cost and improving the work efficiency.

[0028] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model.
