[0026] Implementation

[0027] Please see Figure 1 -4. A dewatering device for a heat exchanger, comprising: a heat exchanger 1, an outer frame 2, a blower 7 and a first three-way valve 5, wherein an inlet pipe 3 and an outlet pipe 4 are provided on the outer wall of the heat exchanger 1, and a conveying pipe 9 is provided inside the outer frame 2, wherein the conveying pipe 9 and the inlet pipe 3 are connected by a flange.

[0028] The first three-way valve 5 is located at the end of the conveying pipe 9, the blower 7 is fixedly installed on the inner wall of the outer frame 2, the output end of the blower 7 is connected to the first three-way valve 5, and the output end of the blower 7 is provided with a heating block 8.

During normal use, the filter assembly 10 can filter water, reducing the probability of scale buildup inside the heat exchanger 1. The filter plate 102 is detachable and can be replaced in a timely manner. First, the vibration motor 12 is fixed above the heat exchanger 1, taking care to avoid weak points. Then, the delivery pipe 9 is connected to the inlet pipe 3 through the connecting flange. Then, the discharge pipe 15 is connected to the outlet pipe 4. Next, the first three-way valve 5 and the second three-way valve 6 are adjusted. Then, the solenoid valve 143 is opened, and cleaning liquid, such as water-based detergent, or electrolyte is injected into the heat exchanger 1 pipe through the injection pipe 141. The electrolyte is electrolyzed through the electrode 142 to clean the scale inside the pipe. Then, the solenoid valve 143 is closed, and the first three-way valve 5 is adjusted to connect the delivery pipe 9 and the blower 7. Then, the second three-way valve 6 is adjusted. Connect the outlet pipe 4 and the waste liquid pipe 11. Then, start the blower 7 and the heating block 8. The blower 7 supplies air into the pipe, and the heating block 8 heats the air. At the same time, the vibration motor 12 is turned on. The vibration motor 12 can effectively vibrate the impurities and water stains inside the pipe for better drying. The air output by the blower 7 is dried more efficiently after being heated by the heating block 8. The liquid blown out by the blower 7 enters the waste liquid pipe 11 through the outlet pipe 4.

[0035] Furthermore, the infusion assembly 14 is provided with an infusion tube 141, an electrode 142 and a solenoid valve 143. The infusion tube 141 is connected to the delivery tube 9. The electrode 142 is located inside the infusion tube 141. The solenoid valve 143 is located on the outer wall of the infusion tube 141 and the electrode 142 is located above the solenoid valve 143.

A second three-way valve 6 is installed inside the discharge pipe 15, and a waste liquid pipe 11 is installed at the other end of the second three-way valve 6.

[0038] Specifically, the waste liquid pipe 11 is designed to discharge cleaning liquid and liquid with more impurities separately, avoiding liquid contamination caused by sharing pipes.

[0039] Furthermore, a collection chamber 13 is provided inside the outer frame 2, and the output end of the waste liquid pipe 11 is located above the collection chamber 13.

[0040] Specifically, the collection chamber 13 can collect the liquid from the waste pipe 11, preventing indiscriminate discharge.
