Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically to a carbon dioxide finned heat exchanger. Background Technology

[0002] A carbon dioxide finned heat exchanger is a device that uses carbon dioxide as the heat exchange medium and enhances heat transfer efficiency through a finned structure. Its core advantage lies in utilizing the properties of carbon dioxide in its supercritical state, which combines the diffuseability of a gas with the high specific heat capacity of a liquid, to achieve efficient heat exchange in a high-pressure environment. The device typically uses stainless steel or copper heat exchange tubes, paired with aluminum or copper fins. These fins are fixed to the tubes using processes such as high-frequency welding to reduce thermal resistance and improve the heat transfer coefficient.

[0003] Chinese Patent Publication No. CN222418648U discloses a hot air internal circulation finned heat exchanger, including a housing, a heat exchange section fixedly installed between the housings, and guide tubes threaded onto the side walls of the housing. A heat circulation section is arranged between the guide tubes. The heat exchange section includes fins, and a dust removal section for dust removal of the fins is arranged between the housing and the heat exchange section. A transmission section is arranged at the top of the dust removal section. The advantage of this application is that the hot fluid in the condenser tube exchanges heat with the cold fluid flowing through the inner cavity of the housing through the fins. The cold fluid is introduced into the housing through the front guide tube, and after heat exchange, it is discharged from the rear guide tube. It is then introduced back into the front guide tube through the return tube and the one-way valve for waste heat recovery and utilization, realizing full circulation of the heat flow. When the motor is started, the transmission wheel drives the lead screw to rotate together, causing the brush plate threaded onto the lead screw to move up and down along the fin surface to remove dust from the fin surface and maintain the high-efficiency heat exchange capacity of the fins.

[0004] In the aforementioned prior art, by controlling the brush plate to move back and forth on the side of the fin, the effect of removing dust from the fin surface can be achieved. However, the brush plate's cleaning motion is relatively simple. Each time the brush plate moves, it can only clean a single position once, which requires frequent control of the brush plate's reciprocating motion to clean a certain position multiple times, resulting in reduced cleaning efficiency. Utility Model Content

[0005] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a carbon dioxide finned heat exchanger that solves the problem mentioned in the background art: the brush plate of the finned heat exchanger can only clean a single position once each time it moves, which requires frequent control of the brush plate's reciprocating motion to clean a certain position multiple times, resulting in reduced cleaning efficiency.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A carbon dioxide finned heat exchanger, comprising:

[0008] A carbon dioxide heat exchanger, wherein the carbon dioxide heat exchanger is provided with a plurality of heat exchange fins, further comprising:

[0009] A cleaning structure is arranged on one side of the carbon dioxide heat exchanger and is used to clean the heat exchange fins inside the carbon dioxide heat exchanger.

[0010] The linkage structure is arranged on the cleaning structure to drive the cleaning structure to reciprocate.

[0011] The blowing structure, located on the cleaning structure, is used to blow away the dust that has been swept up.

[0012] Preferably, the cleaning structure includes:

[0013] The connecting frame is located on one side of the carbon dioxide heat exchanger;

[0014] The U-shaped frame is slidably mounted on the connecting frame.

[0015] The U-shaped carriage is slidably installed inside the U-shaped frame;

[0016] Several sliding rods are evenly and slidably installed inside the U-shaped carriage;

[0017] A connecting bracket is located at one end of the slide bar;

[0018] The bristles are arranged on one side of the connecting frame and in contact with the heat exchange fins;

[0019] The drive component is located on one side of the connecting frame.

[0020] Preferably, the driving component includes:

[0021] Both bearings are located on one side of the connecting frame;

[0022] The lead screw is rotatably mounted inside two bearings, and the lead screw thread is installed inside the U-shaped frame.

[0023] The geared motor is mounted on the corresponding shaft seat, and the output end of the geared motor is located at one end of the lead screw.

[0024] Preferably, the cleaning structure further includes a spring, which is slidably sleeved on the slide rod, with both ends of the spring respectively installed between the U-shaped slide and the connecting frame.

[0025] Preferably, the linkage structure includes:

[0026] A rack is arranged on one side of the carbon dioxide heat exchanger;

[0027] The linkage gear is rotatably mounted on one side of the U-shaped frame;

[0028] The linkage shaft is located on one side of the linkage gear;

[0029] A strip-shaped hole is formed inside the U-shaped carriage, and the linkage shaft is movably installed inside the strip-shaped hole.

[0035] Preferably, the blowing structure further includes several ventilation holes, which are evenly distributed inside the U-shaped carriage and the connecting frame for ventilation.

[0036] The beneficial effects of this utility model are as follows:

[0037] This invention, by controlling the forward and reverse rotation of the output end of the geared motor, can drive the U-shaped frame and brush bristles to reciprocate on the connecting frame.

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] Example 1:

[0050] like Figures 1 to 6 As shown, this utility model provides a carbon dioxide finned heat exchanger, including: a carbon dioxide heat exchanger 1, a plurality of heat exchange fins 101 disposed on the carbon dioxide heat exchanger 1, and a cleaning structure arranged on one side of the carbon dioxide heat exchanger 1 for cleaning the heat exchange fins 101 inside the carbon dioxide heat exchanger 1.

[0051] The cleaning structure includes a connecting frame 2 arranged on one side of the carbon dioxide heat exchanger 1, a U-shaped frame 201 slidably installed on the connecting frame 2, a U-shaped carriage 202 slidably installed inside the U-shaped frame 201, several sliding rods 203 evenly slidably installed inside the U-shaped carriage 202, a connecting frame 204 arranged at one end of the sliding rods 203, bristles 205 arranged on one side of the connecting frame 204 and in contact with the heat exchange fins 101, and a driving component arranged on one side of the connecting frame 2. The driving component can control the U-shaped frame 201 to slide back and forth on one side of the connecting frame 2. Under the movement of the U-shaped frame 201, the bristles 205 can be driven to clean the heat exchange fins 101 and remove dust from the heat exchange fins 101.

[0052] Specifically, the drive assembly includes two bearing seats 206 arranged on one side of the connecting frame 2, a lead screw 207 rotatably installed inside the two bearing seats 206, the lead screw 207 being threaded inside the U-shaped frame 201, and a geared motor 208 arranged on the corresponding bearing seat 206. The output end of the geared motor 208 is arranged at one end of the lead screw 207. Turning on the geared motor 208 can drive the lead screw 207 to rotate inside the bearing seat 206. While the lead screw 207 is rotating, it can drive the U-shaped frame 201 to slide on the connecting frame 2 through the threaded engagement with the U-shaped frame 201.

[0053] The cleaning structure also includes a spring 209 that is slidably sleeved on the slide rod 203. The two ends of the spring 209 are respectively installed between the U-shaped slide 202 and the connecting frame 204. Under the elastic force of the spring 209, the connecting frame 204 and the bristles 205 can be pushed to move towards the heat exchange fins 101, which can improve the adhesion effect between the bristles 205 and the heat exchange fins 101.

[0054] Example 2:

[0055] Based on Example 1, in order to control the reciprocating motion of the cleaning structure and improve the cleaning effect, a linkage structure is arranged on the cleaning structure.

[0056] The linkage structure includes a rack 3 arranged on one side of the carbon dioxide heat exchanger 1, a linkage gear 301 rotatably installed on one side of the U-shaped frame 201, a linkage shaft 302 arranged on one side of the linkage gear 301, and a strip hole 303 opened inside the U-shaped carriage 202. The linkage shaft 302 is movably installed in the strip hole 303. When the U-shaped frame 201 slides, it can drive the linkage gear 301 to move, so that the linkage gear 301 rotates by meshing with the rack 3. The rotating linkage gear 301 can drive the U-shaped carriage 202 to move back and forth through the linkage shaft 302 and the strip hole 303. The moving U-shaped carriage 202 will drive the connecting frame 204 and the brush 205 to move through the slide rod 203, so that the brush 205 can reciprocate and clean the heat exchange fins 101.

[0057] The linkage structure also includes a limiting slide hole 304 inside the U-shaped frame 201. The U-shaped slide 202 is slidably installed in the limiting slide hole 304. When the U-shaped slide 202 moves, it will slide in the limiting slide hole 304. The moving direction of the U-shaped slide 202 can be restricted by the setting of the limiting slide hole 304.

[0058] Example 3:

[0059] Based on Example 1, in order to facilitate blowing the cleaned dust away from the heat exchange fins 101, a blowing structure is arranged on the cleaning structure.

[0060] The blowing structure includes a support frame 4 arranged on a U-shaped frame 201, a dust removal motor 401 arranged on one side of the support frame 4, and a fan blade 402 arranged on the output end of the dust removal motor 401. Turning on the dust removal motor 401 can drive the fan blade 402 to rotate, and the fan blade 402 can blow air toward the heat exchange fins 101, which helps to blow the cleaned dust away from the heat exchange fins 101.

[0061] The blowing structure also includes several ventilation holes 403 evenly opened inside the U-shaped carriage 202 and the connecting frame 204 for ventilation. The airflow blown by the fan blade 402 can pass through the ventilation holes 403, reducing the obstruction effect of the U-shaped carriage 202 and the connecting frame 204 on the fan blade 402.

[0062] Working principle: By turning on the geared motor 208, the lead screw 207 rotates within the bearing 206. Simultaneously, the lead screw 207, through its threaded engagement with the U-shaped frame 201, causes the U-shaped frame 201 to slide on the connecting frame 2. By controlling the forward and reverse rotation of the output end of the geared motor 208, the reciprocating sliding of the U-shaped frame 201 on the connecting frame 2 can be controlled. While sliding, the U-shaped frame 201 drives the linkage gear 301 to move, causing the linkage gear 301 to rotate through meshing with the rack 3. The rotating linkage gear 301 drives the linkage shaft 302 to rotate circumferentially, causing the linkage shaft 302 to move within the slot 30. The U-shaped carriage 202 moves back and forth within the 3-section, and the U-shaped carriage 202 moves back and forth through the slide rod 203, which in turn moves the connecting frame 204 and the brush bristles 205. Under the movement of the U-shaped frame 201, the brush bristles 205 can move back and forth on the heat exchange fins 101 to remove dust. While cleaning, the dust removal motor 401 can be turned on to drive the fan blades 402 to rotate. The fan blades 402 can blow air towards the heat exchange fins 101, which helps to blow the cleaned dust away from the heat exchange fins 101. Furthermore, through the setting of the support frame 4, the dust removal motor 401 and the fan blades 402 can move with the U-shaped frame 201.

[0063] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
