Description

Technical Field

[0001] The present invention relates to the technical field of heating radiators, in particular to a rapid heating radiator with a built-in fan. Background Art

[0002] In the heating system, the radiator device is one of the more important components. The radiator is used to dissipate the heat carried by the pipeline transport medium to the surrounding environment, thereby increasing the temperature of the surrounding environment. It is a terminal device that transfers the heat of the heat medium to the room and has become an indispensable part of life.

[0003] Currently, steel plate radiators are new, high-efficiency, energy-saving radiators made from high-quality cold-rolled low-carbon steel plates. Their greatest feature is their high heat dissipation capacity. Steel plate radiators primarily dissipate heat through convection, but existing steel plate radiators have slow air convection, resulting in poor overall heat dissipation. Furthermore, the flow of hot water within the radiator easily generates scale, which results in poor heat transfer from the hot water within the radiator to the steel plate, affecting the overall heat dissipation of the radiator.

[0004] In addition, when this type of radiator is actually used, dust in the air easily adheres to the steel plate during air convection, which affects the heat dissipation of the steel plate and causes the heat dissipation effect of the radiator to be poor. Therefore, it is necessary to design a fast heating radiator with its own fan. Summary of the Invention

[0029] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explaining the present invention and are not intended to limit the present invention.

[0030] The following is combined with Figures 1-8This embodiment is described in further detail.

[0031] like Figure 1-3 As shown, a fast heating radiator with a built-in fan in this embodiment includes a housing 100, a cavity 201 with upper and lower ends opened is provided in the housing 100, and a heat dissipation component is provided in the cavity 201, wherein, as shown in FIG. Figure 1 and Figure 2 As shown, the housing 100 includes a front panel, a rear panel, and side panels mounted on the left and right sides of the front panel and the rear panel, forming a cavity 201 with upper and lower ends open;

[0032] Among them, the heat dissipation component includes a water inlet pipe 101 and a water outlet pipe 102 with one end extending out of the shell 100, the water inlet pipe 101 and the water outlet pipe 102 are respectively extended through the same side plate, and the water inlet pipe 101 and the water outlet pipe 102 located in the cavity 201 are evenly distributed with connected heat dissipation pipes 210, and the heat dissipation pipes 210 are evenly distributed along their height direction. A lower cover plate 220 is provided at the lower end opening of the cavity 201, and an air inlet 221 is distributed on the lower cover plate 220. An upper cover plate 110 is provided at the upper end opening of the cavity 201, and an air outlet 111 is distributed on the upper cover plate 110. As a result, when the heating radiator is actually used, the heat dissipation component is compatible with the existing water circulation system. The water circulation heating system is connected, and the hot water generated by the water circulation heating system enters through the water inlet pipe 101, flows out through the water outlet pipe 102 through the heat dissipation pipe 210, and returns to the water circulation heating system. The water inlet pipe 101, the water outlet pipe 102 and the heat dissipation pipe 210 are all made of copper pipes. The heat in the hot water passing through the heat dissipation pipe 210 is transferred to the heat dissipation fins 211, thereby heating the air in the cavity 201. The air inlet 221 and the air outlet 111 are arranged so that the outside air can enter the cavity 201 through the air inlet 221, exchange heat with the heat dissipation fins 211, and then be discharged from the air outlet 111. Thus, the heating radiator can provide heat to the outside.

[0033] Among them, a partition 230 is provided in the cavity 201 and above the lower cover 220, and a fan assembly for blowing air upward is provided on the partition 230 corresponding to the heat dissipation pipe 210, and a vibration assembly for driving the lower cover 220 to vibrate is provided on the fan assembly located in the middle; a descaling assembly for scraping scale on the inner wall of the heat dissipation pipe 210 is provided in the heat dissipation pipe 210, and the descaling assembly includes a rotating rod 310 with two ends respectively extending through the water inlet pipe 101 and the water outlet pipe 102, a scraper 701 is provided on the rotating rod 310, and a driving assembly for cooperating with the corresponding fan assembly is provided at the lower end of the rotating rod 310, and a lifting and lowering blocking plate 240 for blocking the air outlet 111 is provided in the cavity 201 and below the upper cover 110, and a clutch assembly cooperating with the upper end of the rotating rod 310 is provided on the blocking plate 240.

[0034] In this embodiment, the fan assembly is provided to promote the upward flow of air in the cavity 201. Compared with the natural convection of the existing air, it can promote the flow of air, thereby enabling the heating radiator to provide heat quickly.

[0035] It should be noted that, by providing the air inlet 221 and the air outlet 111, external dust is allowed to flow with the air and adhere to the heat dissipation fins 211, thereby affecting the heat dissipation of the heat dissipation fins 211. Therefore, in this embodiment, a filter (not shown in the figure) is provided on the lower side surface of the lower cover plate 220 corresponding to the air inlet 221 to filter the air entering the cavity 201 through the air inlet 221. At the same time, in order to prevent dust from entering the cavity 201 through the air outlet 111 and adhering to the heat dissipation fins 211 when the heating radiator is not working, the air outlet 111 is closed by raising and lowering the blocking plate 240, thereby solving the problem of dust adhering to the heat dissipation fins 211 as the air flows.

[0036] In actual use, in order to realize the lifting and lowering of the blocking plate 240, a cylinder fixing plate is relatively arranged on the side wall of the cavity 201 located at the upper part. The cylinder fixing plate is provided with a cylinder 320 for driving the blocking plate 240 to lift and lower. The blocking plate 240 is provided with a notch 241 that is offset from the air outlet 111. The notch 241 is offset from the air outlet 111 so that when the cylinder 320 drives the blocking plate 240 to move upward and fit the upper cover plate 110, the air outlet 111 can be blocked. When the cylinder 320 drives the blocking plate 240 to move downward, the hot air after heat exchange in the cavity 201 can be discharged through the notch 241 and the air outlet 111.

[0037] It should be noted that the flow of hot water in the heat pipe 210 may cause scale to form in the heat pipe 210, thereby affecting the heat transfer from the heat pipe 210 to the heat fins 211, and affecting the heat dissipation effect of the heating radiator. Therefore, the descaling component in this embodiment can scrape and remove the scale on the inner wall of the heat pipe 210. In actual use, a drain valve (not shown in the figure) is provided on the protruding end of the water outlet pipe 102. That is, the drain valve is opened and the descaling component is activated to scrape and remove the scale on the inner wall of the heat pipe 210, so that the scale generated by the scraping can be discharged through the drain valve along with the water remaining in the heat dissipation component.

[0038] The arrangement of the rotating rod 310 and the scraper 701 allows the rotating rod 310 to rotate and drive the scraper 701 to rotate, thereby scraping away the scale on the inner wall of the heat dissipation tube 210.

[0039] Among them, through the setting of the driving component, the driving component can drive the fan component to drive the rotating rod 310 to rotate, thereby realizing the descaling component working with the fan component to perform descaling on the inner wall of the heat dissipation pipe 210;

[0040] In actual use, in order to prevent the heating radiator from scraping the inner wall of the heat pipe 210 by driving the fan assembly through the driving assembly during operation, causing the scale to circulate into the water circulation heating system, which may easily cause damage to the water circulation heating system, in this embodiment, the clutch assembly is set so that in actual use, when the blocking plate 240 moves downward, the clutch assembly is driven to release the engagement with the rotating rod 310. At this time, even if the driving assembly drives the fan assembly to rotate the rotating rod 310, it will not drive the scraper 701 to scrape the heat pipe. 210 is scraped, and when the blocking plate 240 moves up to drive the clutch assembly to cooperate with the rotating rod 310, the driving assembly drives the fan assembly to drive the rotating rod 310 to rotate, and then drives the scraper 701 to scrape the inner wall of the heat pipe 210. As a result, when the heating radiator is working, the driving assembly cannot drive the descaling assembly to work. When the heating radiator is not working, the driving assembly drives the fan assembly to drive the descaling assembly to work, so as to perform maintenance on the heating radiator and at the same time, prevent the scale generated by the descaling assembly from circulating into the water circulation heating system.

[0041] In this embodiment, combined with Figure 5 As shown, a mounting hole is provided on the partition 230 corresponding to the heat dissipation pipe 210, and the fan assembly includes a mounting bracket 510 provided in the mounting hole. A rotatable shaft 521 is provided on the mounting bracket 510 through a dual-axis motor 520, and a fan 522 is provided on the shaft 521.

[0042] In this embodiment, through the above-mentioned structure, the mounting bracket 510 is threadedly connected to the corresponding mounting hole, thereby achieving the installation of the fan assembly on the partition 230;

[0043] The dual-axis motor 520 can drive the rotating shaft 521 to drive the fan 522 to rotate. The fan 522 is used to blow the air at the bottom of the cavity 201 upward, thereby promoting the flow of air in the cavity 201.

[0044] Combine Figure 2 、 3 As shown in Figure 6, in this embodiment, a mounting rod 610 is relatively provided on the bottom wall of the cavity 201 and is arranged through the lower cover plate 220. The through end of the mounting rod 610 is threadedly connected with a nut 611, and a first spring 620 is sleeved on the mounting rod 610 for pushing the lower cover plate 220 to move upward; the vibration component includes a convex ring 250 provided on the lower cover plate 220, and the convex ring 250 is evenly distributed with grooves 531 along its circumference. An inclined surface 532 is provided on one side wall of the groove 531. A top rod 523 that slides against the convex ring 250 is evenly distributed at the lower end of the rotating shaft 521 through a connecting plate. The rotating shaft 521 rotates to drive the top rod 523 to slide into the groove 531 or slide out of the groove 531 along the inclined surface 532, thereby realizing the vibration of the lower cover plate 220.

[0045] In this embodiment, Figure 1 and Figure 3 As shown, air inlet recesses are formed at the lower ends of the front and rear panels, and external air can enter through the air inlet recesses, be filtered by the filter, and then enter the cavity 201 through the air inlet 221;

[0046] The convex ring 250 and the rotating shaft 521 at the middle position are coaxially arranged at the center position of the upper side surface of the lower cover 220. One side wall of the groove 531 is provided with an inclined surface 532, and the other side forms a vertical surface. Therefore, in conjunction with the lifting effect of the first spring 620, the rotating shaft 521 can rotate to drive the push rod 523 to slide into the groove 531 along the vertical surface of the groove 531, and then the push rod 523 abuts against the bottom wall of the groove 531, causing the lower cover 220 to vibrate, so that dust attached to the filter screen on it falls off to ensure the filtering effect of the filter screen. At this time, the rotating shaft 521 continues to rotate, which can drive the push rod 523 to slide out of the groove 531 along the inclined surface 532. As a result, the rotating shaft 521 continues to rotate, which can drive the lower cover 220 to generate continuous vibration, so that the filtering effect of the filter screen on it is better.

[0047] Combine Figure 7 and Figure 8 As shown, in this embodiment, an upper friction disk 710 is provided at the lower end of the rotating rod 310; the driving assembly includes a retaining ring 811 provided on the rotating shaft 521, and a liftable ring 820 is provided on the rotating shaft 521 above the retaining ring 811, and a frustum 821 is provided on the outer wall of the ring 820 along its circumference, and a lower friction disk 830 that can be lifted and lowered and cooperates with the upper friction disk 710 is provided on the rotating shaft 521 above the ring 820, and a driving member for driving the ring 820 to lift and lower is provided in the cavity 201.

[0048] In actual use of this embodiment, a limiting groove is provided on the outer side surface of the rotating shaft 521 and at the upper end thereof along its axial direction. A limiting block is provided in the lower friction plate 830 and extends into the limiting groove. Thus, the key grooves between the rotating shaft 521 and the lower friction plate 830 are engaged, that is, the rotation of the rotating shaft 521 can also rotate the lower friction plate 830.

[0049] Among them, the distance between the lower friction disk 830 and the corresponding upper friction disk 710 is small, that is, due to the obstruction of the upper friction disk 710, the lower friction disk 830 will not separate from the rotating shaft 521 when it rises and falls at the upper end of the rotating shaft 521. As a result, the driving member drives the lower friction disk 830 to move upward along the rotating shaft 521, so that the lower friction disk 830 can be pressed against the upper friction disk 710. There is a large friction force between the two due to the extrusion, which enables the rotating shaft 521 to drive the rotating rod 310 to rotate. When the driving member drives the lower friction disk 830 to move downward along the rotating shaft 521, it is away from the upper friction disk 710, that is, the rotation of the rotating shaft 521 cannot drive the rotating rod 310 to rotate.

[0050] In this embodiment, the driving member includes relatively arranged mounting plates 540, and a screw rod 541 and a guide rod 542 located on both sides of the ring 820 are provided between the mounting plates 540. A movable plate 550 is relatively arranged between the mounting plates 540, the screw rod 541 is threaded through the movable plate 550, and the guide rod 542 is provided through the movable plate 550. The movable plate 550 is provided with an abutment rod 551 abutting against the circular table surface 821, and the screw rod 541 rotates to drive the movable plates 550 to move closer to or away from each other.

[0051] When this embodiment is actually used, the mounting plate 540 is fixed to the front and rear panels by screws so that the driving member can be installed in the cavity 201; wherein, the movable plate 550 is positioned by passing through the guide rod 542, so that the rotation of the screw rod 541 can drive the movable plate 550 to move, wherein the thread provided on the screw rod 541 and the corresponding thread of the movable plate 550 are arranged in reverse symmetry, thereby, the rotation of the screw rod 541 can drive the movable plates 550 to approach each other, and thus can drive the push rod 551 to approach each other, squeezing the circular table surface 821 to make the ring 820 move up along the rotating shaft 521, lifting the lower friction disk 830 and pressing it against the upper friction disk 710, and when the screw rod 541 rotates, it can drive the movable plates 550 to move away from each other, releasing the pressing between the upper friction disk 710 and the lower friction disk 830.

[0052] During actual use of this embodiment, one end of the screw rod 541 extends through the shell 100, and a screw cap 543 is provided at the protruding end of the screw rod 541. Thus, the user can use the screw cap 543 to drive the screw rod 541 to rotate outside the shell 100, making it easier for the driving component to control whether the rotating rod 310 rotates for switching.

[0053] Combine Figure 4 and Figure 7 As shown, in this embodiment, the outer sleeve of the rotating rod 310 is provided with a sleeve 410 whose upper end extends out of the water inlet pipe 101, the scraper 701 is fixedly installed on the outside of the sleeve 410, and a mounting plate 420 is provided outside the protruding end of the sleeve 410, and the upper side surface of the mounting plate 420 is provided with a connecting rod 421 connected to the blocking plate 240; the clutch assembly includes a lower convex ring portion 430 provided on the upper side surface of the mounting plate 420 and sleeved on the outside of the rotating rod 310, and lower ratchet grooves are evenly distributed on the lower convex ring portion 430, and a liftable fixed plate 440 is provided at the upper end portion of the rotating rod 310, and an upper convex ring portion 450 is provided on the fixed plate 440 corresponding to the lower convex ring portion 430, and upper ratchet grooves matching the lower ratchet grooves are evenly distributed on the upper convex ring portion 450.

[0054] When the blocking plate 240 is actually used, the connecting rod 421 can be used to drive the mounting plate 420 and the sleeve 410 to move upward as a whole, thereby enabling the lower ratchet groove to engage with the corresponding upper ratchet groove. At this time, the lower convex ring portion 430 and the upper convex ring portion 450 are matched and fixed, that is, the rotation of the rotating rod 310 can drive the sleeve 410 to rotate, thereby achieving the scraping of the scraper 701; when the blocking plate 240 is moved downward, the mounting plate 420 and the sleeve 410 can be driven to move downward as a whole, thereby releasing the cooperation between the lower convex ring portion 430 and the upper convex ring portion 450. At this time, the rotation of the rotating rod 310 cannot drive the sleeve 410 to rotate, that is, the scraper 701 will not perform the scraping operation.

[0055] A sealing gasket is provided between the sleeve 410 and the rotating rod 310, and a sealing gasket is also provided at the through end of the sleeve 410 and the through end of the rotating rod 310, thereby improving the sealing performance of the rotating rod 310 and the sleeve 410 when installed in the heat dissipation assembly;

[0056] In this embodiment, a spring mounting ring 460 is provided at the upper end of the rotating rod 310, and a groove is provided on the outer wall of the rotating rod 310 and along its axial direction at the upper end. A block that slides into the groove is provided in the fixed disk 440, and a second spring 470 for driving the fixed disk 440 to move downward is provided on the rotating rod 310 located between the spring mounting ring 460 and the fixed disk 440.

[0057] Through the construction in this embodiment, through the matching arrangement of the card slot and the card block, a keyway match is preferably achieved between the fixed disk 440 and the rotating rod 310, that is, the rotation of the rotating rod 310 can drive the fixed disk 440 to rotate. At the same time, the fixed disk 440 can move up and down along the rotating rod 310. Among them, through the arrangement of the second spring 470 and the spring mounting ring 460, when actual use is used, the blocking plate 240 moves up to drive the lower ratchet groove to be not fully engaged with the corresponding upper ratchet groove. At this time, when the dual-axis motor 520 starts to drive the rotating rod 310 to rotate, the fixed disk 440 can be rotated. In combination with the pushing action of the second spring 470, the lower ratchet groove can be better engaged with the corresponding upper ratchet groove, so that the fixed disk 440 drives the sleeve 410 to rotate, driving the scraper 701 to perform scraping operations.

[0058] Working principle: When the heating radiator is working, the cylinder 320 drives the blocking plate 240 to move downward, so that the air outlet 111 is opened. At this time, the water circulation heating system provides hot water to the heat dissipation component, and the dual-axis motor 520 is started to drive the rotating shaft 521 to rotate, so that the fan 522 blows the air in the cavity 201 upward, so that the heating radiator can heat quickly. At the same time, the lower cover 220 is driven to vibrate to ensure the filtering effect of the filter screen on it; when the inner wall of the heat dissipation pipe 210 needs to be descaled, the cylinder 320 drives the blocking plate 240 to move upward to fit the upper cover 110, so that The air outlet 111 is closed, and at the same time, the water circulation heating system stops supplying water to the heat dissipation component. At this time, by screwing the screw cap 543, the screw rod 541 is driven to rotate, and the movable plates 550 are driven to approach each other to move the lower friction disc 830 upward, squeezing the corresponding lower friction disc 830, and then the dual-axis motor 520 is started to drive the rotating rod 310 to drive the sleeve 410 to rotate, and then drive the scraper 701 to scrape the inner wall of the heat dissipation tube 210 to make the scale on it fall off, and finally open the drain valve to allow the scale produced by scraping to be discharged through the drain valve along with the residual water in the heat dissipation component.

[0059] In short, the above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
