[0002] Radiant Floor Heating uses the entire floor as a radiator. The heat medium in the floor's radiant layer evenly heats the entire floor. It utilizes the floor's own heat storage and the law of upward radiation to conduct heat from bottom to top, thereby achieving the purpose of heating. With the development of the times, there are more and more types of heat exchange devices.

[0003] According to the search, the Chinese patent number CN218846990U discloses a closed geothermal heat exchange device, including a base plate, the upper outer surface of the base plate is provided with the closed geothermal heat exchange device body, the left inner surface of the base plate is rotatably connected to a forward and reverse threaded rotating rod, the outer wall of the forward and reverse threaded rotating rod is rotatably connected to a clamping seat, the left outer surface of the clamping seat is provided with a first rubber block, the upper inner surface of the base plate is slidably connected to a movable base, and the right inner surface of the movable base is rotatably connected to a stabilizing arc plate. By adjusting the limit of the first rubber block and the second rubber block, the four sides of the closed geothermal heat exchange device can be installed and fixed, which facilitates the use of the closed geothermal heat exchange device.

[0004] Regarding the above-mentioned related technologies, the inventors believe that although the above-mentioned geothermal heat exchange device achieves a protective effect on the main body by setting up closed protective measures on the outside when in use, its installation process requires the mutual cooperation between the motor, the threaded handle and the clamping plate to complete the installation, and the steps are relatively cumbersome. When protective measures are installed on the main body of the geothermal heat exchange device or the main body needs regular maintenance, the assembly and disassembly of the external protective measures takes a long time, which affects the overall maintenance efficiency when maintaining the main body and is inconvenient for staff to operate.

[0023] A closed geothermal heat exchange method comprises the following steps:

[0024] S1. Closing step: Turn on the first motor to drive the bidirectional screw to rotate.

The T-plate drives the four movable components and the protective plate to approach the geothermal heat exchange device body, so that the subsequent protective plate is close to and fits the outside of the geothermal heat exchange device body, and the flange connection part is located inside the adapter groove. The subsequent set plate continues to approach the geothermal heat exchange device body, so that the set plate will move on the outer surface of the set cylinder and compress the first spring, so that the two protective plates remain stationary.

[0026] S3, heat exchange step: When the device is working, heat exchange can be performed, and the heat exchange tube is the main component of heat exchange, and the heat exchange liquid flows outside and inside it;

[0027] S4. Cleaning step: Turn on the second motor, which will drive the one-way screw to rotate through the two first bevel gears, so that the circular scraper moves to scrape off the water stains on the outer surface of the heat exchange tube. When the one-way screw rotates, it will pass through the outer surface of the roller brush, so that the roller brush cleans the outer surface of the one-way screw. The two second bevel gears will drive the rolling rod and multiple cams to rotate. The elastic force of the third spring makes the ball roll close to the outer surface of the cam, so that the cam can push the rubber hammer to reciprocate and knock on the outer surface of the geothermal heat exchange device body, thereby generating vibration to facilitate the separation of scale and improve the scale treatment effect.

[0028] In summary, the present invention has the following beneficial technical effects:

[0029] (1) The present invention arranges the protective plate, the side protection assembly, the drive assembly, the movable assembly, and the buffer plate, so that the main body of the geothermal heat exchange device can be opened and closed by controlling the first motor, thereby making it more convenient for workers to operate when repairing the main body of the geothermal heat exchange device, thereby improving the efficiency of repair and maintenance;

[0030] (2) The present invention uses a one-way screw, a circular scraper, a cam, and a rubber hammer to clean the outside of the heat exchange tube, thereby preventing too much scale from being retained on the outside of the heat exchange tube and affecting the heat exchange effect;

[0031] (3) The present invention makes it possible to clean the outside of the one-way screw by providing the grooves and roller-shaped brushes, thereby avoiding the accumulation of a large amount of scale on the one-way screw, which would affect the use and transmission of the circular scraper.
