Description

Technical Field

[0001] This utility model relates to the technical field of heating, ventilation and air conditioning, and in particular to a heating, ventilation and air conditioning heat exchange device. Background Technology

[0002] Heat exchangers are core components of HVAC systems, achieving comfortable indoor environmental regulation through efficient heat transfer. With the continuous development of energy-saving technologies, heat exchangers have made significant progress in improving efficiency, reducing energy consumption, and optimizing design.

[0003] The existing patent publication number CN218672471U discloses a novel heat exchange device for HVAC systems, belonging to the field of heat exchange technology. The heat exchange device includes a heat exchange box, an air inlet duct, a heating pipe, and a cooling air guide plate. The air inlet duct is fixedly connected to the heat exchange box, and the heating pipe and cooling air guide plate are fixedly connected inside the heat exchange box. A filter plate is installed inside the air inlet duct and is snap-fitted into it. During use, the staggered distribution of the cooling air guide plate and the installation position of the heating pipe allow for good heat exchange between the heating pipe and the cooling air guide plate without energy loss. The device effectively filters impurities from the air during airflow and facilitates the installation and removal of the filter plate, thereby effectively improving the efficiency and practicality of the heat exchange device.

[0004] In the process of adapting to existing technology, in order to avoid affecting the airflow, the filter plate needs to be disassembled and cleaned, which makes the cleaning process complicated and cumbersome. At the same time, due to the alternation of hot and cold, condensation water is easily generated inside the heat exchange box and remains inside the heat exchange box. Utility Model Content

At the same time, due to the alternation of hot and cold, condensate is easily generated inside the heat exchange box and remains inside the heat exchange box".

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A heating, ventilation, and air conditioning (HVAC) heat exchange device, comprising:

[0030] Reference Figure 1-5 This utility model provides a heating, ventilation, and air conditioning (HVAC) heat exchange device, comprising:

[0031] The main unit 100 includes a heat exchange box 101. An air outlet pipe 102 is installed on one side surface of the heat exchange box 101. The heat exchange box 101 is the prior art. An air inlet pipe 103 is installed on the other side surface of the heat exchange box 101, and a filter plate 104 is fixedly connected to the inner wall surface of the air inlet pipe 103.

[0032] The cleaning unit 200 includes two sets of side plates fixedly connected to one side surface of the air intake pipe 103, and a threaded rod 203 rotatably connected between the side plates. A motor 202 is fixedly connected to the upper surface of the side plates, and the output shaft of the motor 202 is fixedly connected to the threaded rod 203. A threaded cylinder 204 is threadedly connected to the surface of the threaded rod 203, and a connecting plate 205 is fixedly connected to one side of the threaded cylinder 204. A connecting plate 205 is fixedly connected to the lower surface of the connecting plate 205, and a scraper 206 is fixedly connected to the lower surface of the connecting plate 205. One side surface of the scraper 206 is slidably connected to the filter plate 104. A limiting groove is provided on one side of the inner wall of the air intake pipe 103, and the inner wall surface of the limiting groove is slidably connected to the surface of the connecting plate 205, which has a limiting function. A water storage tank 207 is provided inside the air intake pipe 103. A water collection tank 201 is installed on the lower side of the heat exchange box 101, and a water pumping component 208 is provided on one side of the water collection tank 201. The water collection tank 201 is connected to the heat exchange box 101 and can collect the condensate generated by the heat exchange box 101. The rotation of the threaded rod 203 drives the threaded cylinder 204 to move up and down flexibly, thereby driving the scraper 206 to slide on the surface of the filter plate 104 for dust scraping and cleaning.

[0033] The pumping assembly 208 includes a water pump 208a fixedly connected to the heat exchange box 101, and an inlet pipe 208b fixedly connected to the input end of the water pump 208a. The other end of the inlet pipe 208b is fixedly connected to the water collection tank 201. A guide pipe 208c is fixedly connected to the output end of the water pump 208a, and the other end of the guide pipe 208c is fixedly connected to the air inlet pipe 103. The water collection tank 201 is connected to the inlet pipe 208b, and the water storage tank 207 is connected to the guide pipe 208c. The water pump 208a can inject the condensate inside the water collection tank 201 into the water storage tank 207.

[0034] Furthermore, the bottom surface of the inner wall of the water storage tank 207 is provided with a water outlet, and a movable plate 209 is slidably connected to the inner wall surface of the water outlet. Multiple sets of water inlet channels 210 are provided inside the movable plate 209, and all water inlet channels 210 are L-shaped. The lower surface of the movable plate 209 is movably connected to the upper surface of the connecting plate 205 to guide the condensate inside the water storage tank 207 to the surface of the filter plate 104 for cleaning.

[0035] Furthermore, a pressure plate 211 is fixedly connected to the upper surface of the movable plate 209, and the lower surface of the pressure plate 211 is movably connected to the inner wall surface of the water storage tank 207. The weight of the pressure plate 211 presses the movable plate 209 downward, thereby stopping the water from flowing out of the water inlet tank 210, while preventing the movable plate 209 from slipping out of the water outlet.

[0036] Furthermore, the bottom surface of the inner wall of the water collection tank 201 is provided with a water outlet groove 212 that cooperates with the water inlet pipe 208b. The water outlet groove 212 is located at the center of the water collection tank 201, guiding the condensate inside the water collection tank 201 to flow to the water inlet pipe 208b.

[0037] Furthermore, a slider 213 is fixedly connected to the other end of the connecting plate 205, and a fixing rod 214 is slidably connected inside the slider 213. The upper and lower ends of the fixing rod 214 are fixedly connected to the inner wall surface of the air intake pipe 103 to support and limit the connecting plate 205.

[0038] During operation, when the heat exchange box 101 is running, the condensate generated inside the heat exchange box 101 flows into the water collection tank 201. The water pump 208a is started by power, and the water pump 208a draws out the condensate from the water collection tank 201 through the water inlet pipe 208b. Then, the water pump 208a injects the condensate into the water storage tank 207 through the water guide pipe 208c. Then, the condensate enters the water inlet tank 210 and flows to the surface of the filter plate 104 for cleaning. Then, the motor 202 is started by power to drive the threaded rod 203 to rotate. The threaded cylinder 204, which is threaded to the threaded rod 203, drives the connecting plate 205 to move downward, so that the connecting plate 205 drives the scraper 206 to slide downward on the surface of the filter plate 104 to clean the surface of the filter plate 104.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
