Description

Technical Field

[0001] This invention relates to the technical field of thermoelectric cabinets, and more particularly to a self-heating thermoelectric cabinet. Background Technology

[0002] In recent years, with the continuous increase of various large-scale equipment, the demand for power equipment has also gradually increased. Thermoelectric cabinets are an indispensable part of power equipment. Thermoelectric cabinets can effectively protect precision electrical components, thereby ensuring the service life of electrical components and the stability of power supply. However, when electrical components are working, they generate a lot of heat, which causes the temperature inside the thermoelectric cabinet to rise. In order to ensure that the internal electrical components can operate stably, it is necessary to dissipate the heat generated.

[0003] Currently, thermal cabinets typically dissipate heat by creating ventilation slots on the outside of the cabinet. However, this method is slow. Furthermore, to prevent dust and insects from entering the cabinet through these slots, filters are usually installed on their surfaces. However, these filters accumulate dust over time, causing blockages and hindering heat dissipation. Manual cleaning is required. Even with filters, some small particles can still enter the cabinet, damaging internal electrical components. Alternatively, a fixed cooling fan can be installed inside the cabinet, working in conjunction with the ventilation slots to continuously dissipate heat. While this method effectively increases heat dissipation, fixed fans cannot comprehensively and quickly cool the entire interior of the cabinet, and continuous operation increases energy consumption. Therefore, the actual heat dissipation effect of current thermal cabinets is not ideal. Summary of the Invention

[0044] Example 1

[0045] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a self-heating thermoelectric cabinet. This device includes a self-heating thermoelectric cabinet, comprising...

[0046] The installation mechanism 100 includes a cabinet 101, a base 102 fixedly connected to the bottom of the cabinet 101, and a cabinet door 103 adapted to be installed on the outside of the cabinet 101.

[0047] The cabinet 101 is internally fixedly connected to an inner panel 104, and the outer side of the inner panel 104 is provided with a ventilation groove 105. A triggering component 106 is provided on the outer side of the inner panel 104.

[0048] The drive mechanism 200 includes a mounting plate 201 fixedly connected to the bottom of the inner plate 104, a motor 202 adapted to be installed on one side of the mounting plate 201, and a drive shaft 203 fixedly connected to the output end of the motor 202.

[0049] Among them, one end of the drive shaft 203 is hinged to a connecting shaft 204, a limit block 205 is fixedly connected to the outside of the connecting shaft 204, a heat dissipation component 206 is adapted to be installed at one end of the connecting shaft 204, a limit component 207 is provided at the bottom end of the inner plate 104, and a transmission component 208 is provided at the bottom end of the interior of the cabinet 101; and,

[0050] The cleaning mechanism 300 includes a mounting frame 301 fixedly connected to the outside of the cabinet 101, a filter plate 302 disposed inside the mounting frame 301, and a reciprocating component 303 adapted to be installed on the outside of the mounting frame 301. An auxiliary component 304 is disposed on the outside of the mounting frame 301, and a wetting component 305 is disposed on the top of the mounting frame 301.

[0051] Specifically, the triggering component 106 includes a circular cavity 106a opened at the top of the inner plate 104, a first guide block 106b disposed on the inner wall of the circular cavity 106a, and a bimetallic strip 106c fixedly connected to one side of the first guide block 106b.

[0052] The inner wall surface of the circular cavity 106a is provided with a second guide block 106d. The second guide block 106d is configured in two sets, and the two sets of second guide blocks 106d are respectively disposed on both sides of the bimetallic sheet 106c. The first guide block 106b and the second guide block 106d are electrically connected to the motor 202.

[0053] Furthermore, the heat dissipation component 206 includes a rotating shaft 206a rotatably connected to one end of the connecting shaft 204, a heat-dissipating blade 206b fixedly connected to the outside of the rotating shaft 206a, and a bevel gear 206c fixedly connected to the outside of the rotating shaft 206a.

[0054] Preferably, the limiting component 207 includes a fixing rod 207a fixedly connected to the bottom end of the inner plate 104, an annular plate 207b fixedly connected to the bottom end of the fixing rod 207a, and a limiting groove 207c opened on the inner side of the annular plate 207b.

[0055] Among them, the bottom end of the ring plate 207b is fixedly connected to the tooth block 207d, and the bevel gear 206c is meshed with the tooth block 207d.

[0056] During use, when the electrical components inside the thermoelectric cabinet generate a large amount of heat, the bimetallic strip 106c inside the circular cavity 106a bends due to the heat and comes into contact with the second guide blocks 106d on both sides of the bimetallic strip 106c. This connects the second guide blocks 106d with the first guide block 106b through the bimetallic strip 106c, activating the motor 202. The motor 202 then drives the drive shaft 203 to rotate, which in turn drives the connecting shaft 204 to rotate. Because the limiting block 205 slides inside the limiting groove 207c, the connecting shaft 204 rotates along the ring plate 207b, and... As shaft 204 rotates, it drives the rotating shaft 206a located at the front end of the connecting shaft 204 to rotate. With the cooperation of bevel gear 206c and tooth block 207d, the rotating shaft 206a rotates on its own axis while revolving around the central axis, which causes the heat-dissipating blades 206b to rotate. As the heat-dissipating blades 206b revolve around the central axis and rotate on their own axis, they draw in and expel heat from inside the cabinet 101 through the ventilation grooves 105. When the temperature inside the cabinet 101 decreases, the bimetallic strip 106c cools down and returns to its initial state, causing the first guide block 106b to separate from the second guide block 106d. At this time, the motor 202 will stop running.

[0057] In summary, when the internal temperature of the cabinet 101 is too high, causing the bimetallic strip 106c to deform, the first guide block 106b will come into contact with the second guide block 106d, and the motor 202 will be started. Under the starting of the motor 202, the heat dissipation blades 206b will rotate on their own axis and revolve around the central axis. Compared with traditional fixed cooling fans, this can remove the high temperature inside the cabinet 101 more quickly. After the temperature drops, the bimetallic strip 106c will return to its initial state, thereby stopping the motor 202. Thus, the device can automatically dissipate heat according to the internal temperature of the cabinet 101, effectively saving energy.

[0058] Example 2

[0059] Reference Figures 1-9 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the transmission component 208 includes a windshield 208a disposed at the bottom of the cabinet 101, a rotating rod 208b rotatably connected inside the windshield 208a, and a transmission blade 208c fixedly connected to the outside of the rotating rod 208b. A double-layer turntable 208d is fixedly connected to the bottom of the rotating rod 208b.

[0060] Furthermore, the reciprocating component 303 includes a reciprocating screw 303a rotatably connected inside the mounting frame 301, a driven turntable 303b fixedly connected to the outside of the reciprocating screw 303a, and a belt 303c disposed on the outside of the driven turntable 303b, with the other end of the belt 303c disposed on the outside of the double-layer turntable 208d.

[0061] Among them, the outer side of the reciprocating screw 303a is threadedly connected to the sliding sleeve 303d, and the outer side of the sliding sleeve 303d is fixedly connected to the scraper 303e.

[0062] Furthermore, the wetting component 305 includes a water storage box 305a fixedly connected to the top of the mounting frame 301, a drain groove 305b opened on the outside of the water storage box 305a, and a connecting groove 305c opened inside the water storage box 305a.

[0063] The connecting groove 305c is provided with a wetted cotton 305d inside, and one end of the wetted cotton 305d is located at the top inside the mounting frame 301.

[0064] In operation, as the fan blades 206b rotate on their own axis and revolve around the sun, they blow on the drive blades 208c located inside the wind deflector 208a. This causes the drive blades 208c to rotate under the force of the wind. The design of the wind deflector 208a ensures that the fan blades 206b can only blow on the drive blades 208c in one direction. As the drive blades 208c rotate, they also drive the double-layered turntable 208d located at the bottom of the rotating rod 208b to rotate. d drives the driven turntable 303b to rotate via belt 303c. The rotation of the driven turntable 303b will drive the reciprocating screw 303a to rotate, which will drive the sliding sleeve 303d located on the outside of the reciprocating screw 303a to slide back and forth. The sliding sleeve 303d will drive the scraper 303e to slide back and forth, so that the scraper 303e can remove the dust adsorbed on the surface of the filter plate 302 while sliding back and forth, thus avoiding the situation where dust will clog the filter plate 302 and affect the normal heat dissipation after a long time.

[0065] Furthermore, as the scraper 303e slides back and forth, it squeezes the wetted cotton 305d, causing the water inside the cotton 305d to be squeezed out and water to adhere to the surface of the scraper 303e. The scraper 303e with water adhering to it can effectively improve the cleaning effect on the filter plate 302 and wet the dust scraped off by the scraper 303e, thus preventing the dust from flying around and further improving the usability of the equipment. If the equipment is installed indoors, water can be added to the water storage box 305a manually. If the equipment is installed outdoors, the water storage box 305a can also collect rainwater, thus reducing the frequency of manual water addition. In addition, the design of the trough 305b can effectively prevent excessive water from being stored in the water storage box 305a and leaking out from the connecting groove 305c, further improving the practicality of the equipment.

[0066] In summary, while the heat-dissipating blades 206b rapidly dissipate heat through their rotation and revolution, they also drive the transmission blades 208c to rotate. This, in turn, drives the scraper 303e, located outside the reciprocating screw 303a, to slide back and forth. The scraper 303e cleans the filter plate 302, and the liquid inside the soaked cotton 305d adheres to its surface, further enhancing the cleaning effect. Furthermore, the scraper 303e only cleans the filter plate 302 when the heat-dissipating blades 206b are blowing in the direction of the transmission blades 208c. If the heat-dissipating blades 206b are not blowing in that direction, the scraper 303e stops sliding. Thus, the combined airflow from the heat-dissipating blades 206b, along with the cleaning action of the scraper 303e, effectively removes dust, preventing it from entering the equipment through the filter plate 302 and significantly improving the equipment's practicality.

[0067] Example 3

[0068] Reference Figures 1-11 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the auxiliary component 304 includes a slide cylinder 304a fixedly connected to the bottom of the cabinet 101, a slide rod 304b slidably connected to the top of the slide cylinder 304a, and a piston 304c fixedly connected to the bottom of the slide rod 304b. The slide cylinder 304a is filled with a low-boiling-point liquid 304d, and the top of the slide rod 304b is fixedly connected to a connecting rod 304e.

[0069] The top of the connecting rod 304e is provided with a positioning component 304f, and the inside of the mounting frame 301 is provided with a protective component 304g.

[0070] Furthermore, the positioning component 304f includes a strip 304f-1 fixedly connected to the top of the connecting rod 304e and a positioning block 304f-2 fixedly connected to the outside of the strip 304f-1.

[0071] Furthermore, the protective component 304g includes a gear 304g-1 rotatably connected inside the mounting frame 301 and a baffle 304g-2 fixedly connected to one end of the gear 304g-1.

[0072] During operation, as the heat-dissipating blades 206b rotate, they blow a large amount of hot gas towards the baffle 304g-2. This wind force opens the baffle 304g-2, causing it to drive the gear 304g-1 to rotate. The hot gas also heats the low-boiling-point liquid 304d inside the slide cylinder 304a, causing it to vaporize. This vaporization pushes the piston 304c upwards, which in turn drives the strip 304f-1 via the slide rod 304b and connecting rod 304e. This causes the positioning block 304f-2 on the outer side of the strip 304f-1 to slide upwards, limiting the gear 304g-1 and preventing it from rotating. Thus, when the heat-dissipating blades 206b... When rotated to the other side, the baffle 304g-2 can still be opened, allowing the high-temperature gas inside the equipment to dissipate quickly and improving the heat dissipation effect. When the temperature inside the equipment drops, the motor 202 stops rotating and the low-boiling-point liquid 304d inside the slide 304a cools down, causing the gas from the vaporization of the low-boiling-point liquid 304d to liquefy, causing the piston to slide down. This causes the positioning block 304f-2 on the outside of the strip 304f-1 to slide down, separating the positioning block 304f-2 from the gear 304g-1. At this time, the baffle 304g-2 slides down, blocking the filter plate 302 and preventing some fine dust from entering the equipment through the filter plate 302. This ensures that the equipment can effectively dissipate heat while preventing dust from damaging the electrical components inside the cabinet 101.

[0073] In summary, when the internal temperature of the cabinet 101 rises, the motor 202 will start, which will drive the heat-dissipating blades 206b to rotate and revolve. Under the airflow of the heat-dissipating blades 206b, the baffle 304g-2 will open, and the positioning block 304f-2 will slide up and contact the gear 304g-1, thus ensuring that the baffle 304g-2 is always open. The airflow of the heat-dissipating blades 206b will drive the transmission blades 208c to rotate, which will drive the scraper 303e to clean the filter plate 302. When the internal temperature of the cabinet 101 drops, the motor 202 will stop running, which will cause the baffle 304g-2 to fall and block fine particles.

[0074] When the internal temperature of the equipment becomes too high, the fan blades 206b will rotate and revolve, which can quickly dissipate the heat inside the equipment. At the same time, the filter plate 302 can be effectively cleaned. When the temperature drops, the baffle 304g-2 will slide down, effectively blocking some of the fine particles that have passed through the filter plate 302, thereby effectively improving the service life of the internal electrical components. Moreover, the automatic heat dissipation can effectively save energy, thus greatly improving the practicality of the equipment.
