Description

Technical Field

[0001] This invention relates to the field of radiator technology, specifically to an intelligent radiator with multi-channel zone temperature control. Background Technology

[0002] Radiators (also known as heating radiators) are heating devices primarily used in cold northern regions during winter. They serve to keep the body warm. Cast iron radiators were commonly used in the past, but now radiators made of a variety of materials have been developed. They can now be broadly classified into steel radiators and copper-aluminum composite radiators.

[0003] Copper-aluminum composite radiators have good corrosion resistance and excellent heat dissipation. When water flows through them, they dissipate heat quickly, and they cool down even faster after the water is turned off. Compared to steel radiators, copper pipes have better corrosion resistance and a longer service life.

[0004] Patent application CN201310585709.8 discloses a radiator composed of multiple heat dissipation units. Each heat dissipation unit includes a high-pressure formed upper cast aluminum connector, a heat dissipation aluminum profile, a lower cast aluminum connector, and interconnected steel upper pipe, steel riser, and steel lower pipe. It also includes heat-conducting plates installed inside the steel riser. Each heat-conducting plate comprises a metal sheet and arc-shaped connecting pieces at both ends of the metal sheet. The outer wall of the connecting pieces is in close contact with the inner wall of the steel riser. The heat-conducting plates transfer heat energy from water inside the steel riser that cannot be directly contacted to the top of the steel riser, and ultimately dissipate the heat energy, thus improving efficiency.

[0005] In the existing production of copper-aluminum composite radiators, manufacturers need to consider production costs, service life, and heat dissipation effect. The simplest way to improve the heat dissipation performance of copper-aluminum composite radiators is to increase the size of the aluminum fins and the area of ​​the copper tubes. Therefore, copper-aluminum composite radiators with different aluminum fin sizes and copper tube sizes are set according to the usage scenario and product classification. Beyond this, the improvement of the heat dissipation performance of copper-aluminum composite radiators has begun to focus on the surface treatment and shape changes of the aluminum fins. However, this treatment of aluminum fins requires the purchase of a variety of large-scale equipment, which increases the pressure of cost control. Summary of the Invention

[0006] To address the aforementioned shortcomings of existing technologies, this invention provides a smart radiator with multi-channel zoned temperature control, which effectively solves the problem of how to better improve the heat dissipation performance of copper-aluminum composite radiators.

[0007] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a multi-channel zoned temperature control intelligent radiator, comprising two main pipes and plugs at the ends of the main pipes, multiple copper-aluminum composite heat sinks, wherein copper pipes are inserted into the copper-aluminum composite heat sinks, and further comprising: The copper-aluminum composite heat sink is equipped with an exhaust cover on top, which has a door with a certain opening and closing angle to form an exhaust port for outward exhaust. The bottom of the copper-aluminum composite heat sink is equipped with an air intake cover, which has a door with a certain opening and closing angle to form an air intake port for inward air intake.

[0008] Furthermore, side plates are fixedly connected to the outer sides of the leftmost and rightmost copper-aluminum composite heat sinks, and several servo motors are embedded and fixedly connected to the side plates. The servo motors are used to drive the doors on the exhaust top cover and the intake bottom cover to open and close.

[0009] Furthermore, the air outlet cover includes a frame and two movable doors symmetrically and rotatably connected to the frame. The pivot of the movable door is located at the bottom of the side of the movable door. A diverter is fixedly connected to the bottom of the top plate of the frame. The diverter is used to guide the airflow toward the movable door. A connecting rod is rotatably connected to the outer side of the movable door.

[0010] Furthermore, the air intake bottom cover includes a frame two and two movable plates two symmetrically rotatably connected to the frame two, as well as two screens symmetrically fixedly connected to the inner side of the frame two. The pivot of the movable plate two is located at the bottom of the side of the movable plate two, and a connecting rod is rotatably connected to the bottom of the outer side of the movable plate two.

[0011] Furthermore, multiple connecting rods on the same side and in the same horizontal direction are interconnected to connect multiple connecting rods and cause the movable plate two or the movable door one to move simultaneously through the connecting rods. The servo motor is fixedly connected to the rotating shaft of the outermost movable plate two and the movable door one.

[0012] Furthermore, the diverter includes a vertical plate, an arc-shaped backflow plate, and a sleeve from top to bottom. The sleeve is symmetrically fixedly connected to a baffle plate in the left and right directions. The sleeve is fitted on the outside of the copper pipe. The vertical plates are symmetrically distributed on both sides of the main pipe and are connected to the sleeve by the naturally extending arc-shaped backflow plate. The baffle plate is parallel to the second movable plate and the first movable door, and symmetrically separates the airflow rising to the vicinity of the first movable door.

[0013] Furthermore, the copper-aluminum composite heat sink includes a gasket and an aluminum tube at the center. The aluminum tube is for inserting a copper tube. After the copper tube expands, it fits firmly against the aluminum tube. Horizontal or vertical aluminum fins are distributed on the outer side of the aluminum tube. Outer fins are distributed outside the aluminum fins. The gasket is distributed at the edge of the outer fins to fill the gaps between adjacent frame one, outer fins and two sides of the frame.

[0014] Furthermore, the top of the aluminum tube, outer fins, and aluminum fins are beveled to form a top slope, reducing obstruction to upward airflow. The angle of the top slope is 10° to 15°.

[0015] Furthermore, the bottom of the aluminum tube, outer fins, and aluminum fins is beveled to form a bottom slope, increasing the downward air intake angle; The angle of the bottom slope is 45°.

[0016] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. Through the movable doors 1 and 2 that can be opened and closed, an airflow channel can be formed inside the copper-aluminum composite heat sink. When the temperature rises, the upward flow of high-temperature air is used to drive the airflow inside the copper-aluminum composite heat sink. The top and bottom slopes ensure smooth airflow at the top and increase the air intake area at the bottom. With the help of gaskets and side plates, the interference of weak external airflow is reduced and the chimney effect is enhanced.

[0017] 2. By setting a diverter at the top, the rising airflow can be precisely guided and diverted, reducing mutual interference between airflows and reducing the generation of eddies; the beveled structure at the top and bottom of the heat sink reduces the airflow resistance and increases the air intake area, respectively. Combined with the gasket sealing the gaps, it ensures stable and smooth airflow and further improves the uniformity of heat dissipation. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] The present invention will be further described below with reference to embodiments.

[0023] Example: A multi-channel zoned temperature control intelligent radiator includes two main pipes 1, plugs 2 at the ends of the main pipes 1, and multiple copper-aluminum composite heat sinks 3. Copper pipes 4 are inserted into the copper-aluminum composite heat sinks 3. The radiator also includes: The top of the copper-aluminum composite heat sink 3 is equipped with an exhaust cover 5, which has a door with a certain opening and closing angle to form an exhaust port for outward exhaust. The bottom of the copper-aluminum composite heat sink 3 is equipped with an air intake cover 6, which has a door with a certain opening and closing angle to form an air intake port for inward air intake.

[0024] Specifically, the outer sides of the copper-aluminum composite heat sink 3 on the far left and far right are fixedly connected to side plates 7. Several servo motors 8 are embedded and fixedly connected to the side plates 7. The servo motors 8 are used to drive the doors on the exhaust top cover 5 and the intake bottom cover 6 to open and close.

[0025] The copper-aluminum composite radiator has a main pipe 1 and a copper-aluminum composite heat sink 3. A copper tube 4 is inserted into the copper-aluminum composite heat sink 3. After the copper tube 4 is expanded, it forms an interference fit with the copper-aluminum composite heat sink 3, so that the two are firmly attached. After the main pipe 1 is drilled, multiple copper-aluminum composite heat sinks 3 are welded. Then, after passing the air tightness test, the painting work is carried out. After installing the air outlet top cover 5 and the air inlet bottom cover 6, the production is completed by packaging.

[0026] The exhaust top cover 5 and the intake bottom cover 6 are snapped onto the outside of the main pipe 1 using a snap-fit ​​structure, located at the top and bottom of the copper-aluminum composite heat sink 3 respectively. Side plates 7 are snapped onto the outside of the leftmost and rightmost copper-aluminum composite heat sink 3, serving a decorative purpose and reducing the impact of airflow. When the high-temperature water flows through the main pipe 1, it will be diverted into multiple copper pipes 4 and flow out from another main pipe 1. During the heat transfer, the multiple copper-aluminum composite heat sinks 3 will also have a certain temperature, thereby heating the nearby air and achieving the purpose of raising the indoor temperature.

[0027] When the copper-aluminum composite radiator is first put into use, the door on the exhaust top cover 5 and the intake bottom cover 6 can be driven by the servo motor 8 to flip it outward, so that an air intake space is formed below the copper-aluminum composite radiator 3 and an air outlet space is formed above the copper-aluminum composite radiator 3. Since the copper pipe 4 is located in the center of the copper-aluminum composite radiator 3, the temperature at the center of the copper-aluminum composite radiator 3 is undoubtedly higher, that is, the internal temperature is higher. Once the top space of the copper-aluminum composite radiator 3 is opened, the heated airflow will flow upward. The lower temperature air at the bottom will flow in through the door of the intake bottom cover 6, and the higher temperature air will flow out through the door of the exhaust top cover 5, achieving the purpose of creating a chimney effect, enhancing the airflow near the copper-aluminum composite radiator 3, thereby improving the heat dissipation effect, allowing air to flow into the interior of the copper-aluminum composite radiator 3, and carrying away the heat on the copper-aluminum composite radiator 3 in an orderly manner.

[0028] It should be noted that the plug 2 needs to be removed during user installation, and during installation, the exhaust top cover 5 should be on top and the intake bottom cover 6 on the bottom. The choice of airflow channel depends on the user's usage scenario. The servo motor 8 can be installed on both sides of the side plate 7, or on the exhaust top cover 5 and intake bottom cover 6 of each copper-aluminum composite heat sink 3. If each exhaust top cover 5 and intake bottom cover 6 is equipped with a servo motor 8, it is possible to control whether a lower intake and upper exhaust airflow channel is formed on a single copper-aluminum composite heat sink 3. This assembly method requires slots to be cut on the exhaust top cover 5 and intake bottom cover 6 for the servo motor 8 to be placed individually. Combined with the temperature control sensor, when the copper-aluminum composite heat sink 3 is overheated or just opened, the door on the exhaust top cover 5 and intake bottom cover 6 of a certain copper-aluminum composite heat sink 3 can be opened individually to enhance airflow.

[0029] Specifically, the air outlet cover 5 includes a frame 501 and two movable doors 502 symmetrically rotatably connected to the frame 501. The pivot of the movable door 502 is located at the bottom side of the movable door 502. A diverter 503 is fixedly connected to the bottom of the top plate of the frame 501. The diverter 503 is used to guide the airflow toward the movable door 502. A connecting rod 9 is rotatably connected to the outer side of the movable door 502. Multiple connecting rods 9 on the same side and in the same horizontal direction can be connected to each other using sleeves or buckles or other related structures. Alternatively, multiple connecting rods 9 can be connected by welding after assembly. The connecting rods 9 can be used to make the second movable plate 602 or the first movable door 502 move simultaneously. The servo motor 8 is fixedly connected to the pivot of the outermost second movable plate 602 and the first movable door 502.

[0030] The rotation center of the movable door 502 is located at the bottom, and the rotation angle is 15° to 30°. Because the space required for the rising airflow is not too large, the outflow angle of the rising airflow can be appropriately narrowed to increase the airflow speed and enhance the negative pressure brought by the airflow speed, thereby increasing the downward air intake effect. The movable door 502 is used in conjunction with the diverter 503. The diverter 503 is sleeved on the end of the copper tube 4 to guide the direction of the rising airflow and reduce the airflow angle to help increase the airflow speed.

[0031] The diverter 503 includes, from top to bottom, a vertical plate 5031, an arc-shaped backflow plate 5032, and a sleeve 5033. The sleeve 5033 is symmetrically fixedly connected to a partition 5034 in the left and right directions. The sleeve 5033 is sleeved on the outside of the copper pipe 4. The vertical plates 5031 are symmetrically distributed on both sides of the main pipe 1 and are connected to the sleeve 5033 by the naturally extending arc-shaped backflow plate 5032. The partition 5034 is parallel to the movable plate 602 and the movable door 502, and symmetrically separates the airflow that rises to the vicinity of the movable door 502. The partition 5034 separates the copper-aluminum composite heat sink 3 in the horizontal direction. The movable door 502 and movable plate 602 are symmetrically distributed on the exhaust top cover 5 and the intake bottom cover 6, so that there are two air flow channels on the upper inner side of the copper-aluminum composite heat sink 3. The main pipe 1 is above the partition 5034. The airflow will also be separated by the obstruction of the main pipe 1 and flow outward from the two movable doors 502 respectively, reducing the mutual influence between the two airflows. When the airflow flows out after passing through the copper-aluminum composite heat sink 3, the flow divider 503 reduces the generation of eddies and strengthens the guidance of airflow.

[0032] Among them, the connecting rod 9 on the movable door 1 502 and the movable plate 2 602 is locked in the limiting hole on the outside. The connecting rod 9 can rotate in the limiting hole. The connecting rod 9 has two functions: one is to connect the adjacent movable plate 2 602 or movable door 1 502, and the other is to act as a clothes rack. Users can hang some small items such as socks and towels on the connecting rod 9, so that they do not have to be placed directly on the copper-aluminum composite heat sink 3.

[0033] Specifically, the air intake bottom cover 6 includes a frame 601 and two movable plates 602 symmetrically rotatably connected to the frame 601, as well as two screens 603 symmetrically fixedly connected to the inner side of the frame 601. The pivot of the movable plate 602 is located at the bottom side of the movable plate 602, and a connecting rod 9 is rotatably connected to the bottom outer side of the movable plate 602.

[0034] The rotation center of the movable plate 602 is also located at the bottom. The rotation angle should be 30° to 45°. A larger angle can increase the air intake area. When the angle is smaller, the space is smaller and the air intake flow is also smaller. The screen 603 is used to prevent debris from entering the inside of the copper-aluminum composite heat sink 3.

[0035] Specifically, the copper-aluminum composite heat sink 3 includes a pad 306 and an aluminum tube 301 in the center. The aluminum tube 301 is for the copper tube 4 to be inserted. After the copper tube 4 expands, it is firmly attached to the aluminum tube 301. The outer side of the aluminum tube 301 is distributed with transverse or longitudinal aluminum fins 305. The outer fins 303 are distributed outside the aluminum fins 305. The pad 306 is distributed at the edge of the outer fins 303 to fill the gap between the adjacent frame 1 501, the outer fins 303 and the side of the frame 2 601. The top of the aluminum tube 301, outer fin 303 and aluminum fin 305 are obliquely cut to form a top slope 302, which reduces the obstruction of upward airflow; the angle of the top slope 302 is 10° to 15°. The bottom of the aluminum tube 301, outer fin 303 and aluminum fin 305 are obliquely cut to form a bottom slope 304, which increases the downward air intake angle; the angle of the bottom slope 304 is 45°.

[0036] To reduce dust adhesion on the outer fins 303 and aluminum fins 305, an oleophilic and hydrophobic or dust-repellent coating can be sprayed onto the outer fins 303 and aluminum fins 305, or a smooth anodizing process can be performed.

[0037] The top bevel 302 formed by the oblique cut at the top of the aluminum tube 301, outer fin 303, and aluminum fin 305 can increase the outflow area when the airflow flows out, allowing the rising airflow to be smoothly discharged. The bottom bevel 304 with a large oblique cut at the bottom increases the air inlet area, and the 45° angle of the bottom bevel 304 maximizes the air inlet area, providing a better air inlet and outlet channel. In addition, the gap between the same side edge of frame one 501, outer fin 303, and frame two 601 is filled by a gasket 306 to reduce the impact of this part of the weak airflow on the rising airflow and ensure the stability of the rising airflow.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
