Description

Technical Field

[0001] This utility model relates to the field of radiator heat dissipation technology, specifically to an auxiliary heat dissipation device for radiators. Background Technology

[0002] In northern my country, radiators are widely used. Their heat dissipation is primarily radiant, supplemented by convection. They heat circulating water using a wall-mounted boiler or boiler, which then transmits the heat through pipes to radiators, ultimately outputting a suitable temperature to raise the indoor temperature. However, radiators dissipate heat from the sides. Due to the physical principle that hot air rises and cold air sinks, the temperature distribution is uneven. In other words, radiators don't radiate heat to the floor, resulting in colder floors. In centralized heating systems, there are instances of high daytime temperatures and low nighttime temperatures due to insufficient heat dissipation. Municipal heating systems also experience insufficient heat supply to end-users due to heat loss at the front end. Furthermore, many older residential buildings in my country currently use traditional cast iron radiators, which have relatively low heat dissipation efficiency.

[0003] Existing auxiliary heat dissipation devices mostly involve directly fixing the fan to the radiator for forced convection to assist in heat dissipation. However, this method has the following problems: 1. Since the surface area of ​​the heat dissipation medium is the same as the original radiator area, a stronger airflow is required to achieve the ideal heat dissipation effect, which results in greater noise; 2. The fan speed is mostly manually adjustable, lacking automatic speed adjustment function; 3. Relying on the gap between the fan and the radiator for convection heat dissipation, a large number of fans need to be arranged in an array to achieve a satisfactory convection heat dissipation effect, which increases the cost of the fans. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides an auxiliary heat dissipation device for radiators. The technical problem to be solved by this utility model is achieved through the following technical solution:

[0005] A radiator auxiliary heat dissipation device includes a housing, a heat-conducting component, a controller, and a temperature sensor. The housing is fixed to the radiator via first connecting rods on both sides. The heat-conducting component is disposed inside the housing and includes a heat-conducting pad, a heat-collecting plate, and aluminum fins. The heat-conducting pad is arranged side-by-side on the radiator at the bottom of the housing. The heat-collecting plate is attached to the upper surface of the heat-conducting pad and connected to the top of the housing via a second connecting rod. The aluminum fins are located above the heat-collecting plate and connected to it. The temperature sensor is attached to the radiator. The housing has an air outlet and an air inlet at both ends. A fan is installed at the air outlet. The controller is electrically connected to the temperature sensor and the fan, respectively.

[0006] Furthermore, the heat-conducting components can be one or more, and when there are multiple heat-conducting components, they are arranged side by side on the radiator.

[0007] Furthermore, the heat collection plate is connected to the aluminum fins via a U-shaped heat pipe, with one side of the U-shaped heat pipe inserted into the heat collection plate and the other side inserted into the aluminum fins.

[0008] Furthermore, the aluminum fins are fixed to the heat collection plate.

[0009] Furthermore, one end of the second connecting rod is movably inserted into the housing, and the other end is threadedly connected to the heat collection plate; and a first limiting plate is provided at one end of the second connecting rod, the first limiting plate being located outside the housing; a spring is fitted on the second connecting rod, and the two ends of the spring abut against the housing and the heat collection plate respectively and are in a compressed state.

[0010] Furthermore, several arc-shaped grooves are provided on both sides of the housing, and the first connecting rod is located in the arc-shaped grooves; the upper end of the first connecting rod is threadedly connected to a second limiting plate, and the lower end is threadedly connected to an adjusting block. After the adjusting block adjusts the length of the first connecting rod extending into the radiator, it extends into the radiator together with one end of the first connecting rod for positioning. At the same time, the position of the second limiting plate on the first connecting rod is adjusted so that the second limiting plate is pressed against the upper end face of the housing, thereby fixing the housing to the radiator.

[0011] Furthermore, the thermal pad is made of thermally conductive silicone grease; the heat collection plate is made of aluminum or copper.

[0012] Furthermore, a dustproof net is installed at the air inlet.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model uses a heat-conducting pad to transfer the temperature on the radiator to the heat collection plate, and then the heat collection plate to the aluminum fins with a larger surface area, thereby increasing the heat dissipation area. The hot air is then evenly transferred to the indoor space by the fan, which improves the heat dissipation efficiency of the radiator. This allows the ideal heat exchange effect to be achieved at a relatively low wind speed, while also making the temperature in different parts of the room as uniform as possible, thus increasing the comfort of the human body.

[0015] 2. The controller intelligently adjusts the fan speed according to the radiator temperature to improve the indoor heating effect.

Detailed Implementation

[0029] The present invention will be further described in detail below with reference to specific embodiments, but the implementation of the present invention is not limited thereto.

[0030] Please see Figures 1-12This utility model discloses an auxiliary heat dissipation device for a radiator, specifically including a housing 1, two heat-conducting components 2, a controller 3, and a temperature sensor 4. The housing 1 is fixed to the radiator by first connecting rods 5 on both sides. The heat-conducting components 2 are disposed inside the housing 1 and include a heat-conducting pad 2-1, a heat-collecting plate 2-2, and aluminum fins 2-3. That is, in this utility model embodiment, there are two of each of the heat-conducting pad 2-1, heat-collecting plate 2-2, and aluminum fins 2-3, and the heat-conducting pad 2-1, heat-collecting plate 2-2, and aluminum fins 2-3 are arranged in a one-to-one correspondence. The housing 1 is made of aluminum material, which has good heat dissipation effect, light weight, and high cost performance. The heat-conducting pads 2-1 are pasted side by side on two adjacent heat dissipation fins of the radiator at the bottom of the housing 1, and the heat-collecting plates 2-2 are pasted with thermal grease. On the upper surface of the corresponding heat-conducting pad 2-1, mounting plates 2-2-1 are provided on all four sides of the heat collection plate 2-2, and are connected to the top of the housing 1 through the second connecting rod 6 provided in the mounting plate 2-2-1; the aluminum fins 2-3 are located above the corresponding heat collection plate 2-2 and are connected to the heat collection plate 2-2; the temperature sensor 4 is attached to the radiator with thermally conductive silicone to collect the temperature of the radiator; the housing 1 has an air outlet 1-1 and an air inlet 1-2 at both ends, and a driven fan 1-3 is installed at the air outlet 1-1; the controller 3 is electrically connected to the temperature sensor 4 and the fan 1-3 respectively, and the controller 3 controls the start, stop and speed of the fan 1-3 according to the radiator temperature monitored by the temperature sensor 4.

[0031] Specifically, the temperature sensor 4 is a thermocouple sensor, which can be installed at any position on the radiator; the controller 3 is the existing fan controller 3, model JPF4816, which only needs to set the fan start temperature and maximum speed temperature, and the fan speed control is linear control; the speed of the fans 1-3 can be adjusted in real time according to the temperature of the radiator, and the start and stop of the fans 1-3 can be controlled at the same time. Figure 11 Taking the fan starting at 30℃ and reaching maximum speed at 90℃ as an example, a graph showing the relationship between fan speed ratio and radiator temperature was drawn. The purpose of setting the upper temperature limit above the actual upper temperature limit of the radiator is to prevent noise caused by the fan running at full speed.

[0032] Preferably, the thermal pad 2-1 is made of thermally conductive silicone grease; the heat collection plate 2-2 is made of aluminum or copper.

[0033] The heat is transferred from the radiator to the heat collector plate 2-2 via the heat-conducting pad 2-1, and then to the aluminum fins 2-3 with a larger surface area via the heat collector plate 2-2, increasing the heat dissipation area. The hot air is then evenly distributed to the indoor space by the fan 1-3, which improves the heat dissipation efficiency of the radiator and makes the temperature in all parts of the room as uniform as possible, thereby increasing the comfort of the human body.

[0034] like Figures 1-3 As shown, in a specific embodiment of this utility model, the heat collection plate 2-2 is connected to the aluminum fins 2-3 through a U-shaped heat pipe 2-4. One side of the U-shaped heat pipe 2-4 is horizontally inserted into the heat collection plate 2-2, and the other side is horizontally inserted into the aluminum fins 2-3. The heat from the heat collection plate 2-2 is transferred to the aluminum fins 2-3 through the U-shaped heat pipe 2-4.

[0035] like Figures 4-6 As shown, in another specific embodiment of this utility model, the aluminum fins 2-3 are directly fixed on the heat collection plate 2-2, and the heat on the heat collection plate 2-2 is directly transferred to the aluminum fins 2-3; furthermore, the aluminum fins 2-3 and the heat collection plate 2-2 are integrally formed, which is convenient for processing.

[0036] Furthermore, the second connecting rod 6 has a smooth end connected to the housing 1, and the other end connected to the heat collection plate 2-2 has threads on its outer surface. One end is movably inserted into the housing, and the other end is threaded to the heat collection plate 2-2 via a mounting plate 2-2-1 provided on the heat collection plate 2-2. A first limiting plate 6-1 is provided at the top of the smooth end of the second connecting rod 6, and the first limiting plate 6-1 is located outside the housing 1. A spring 7 is fitted on the second connecting rod 6, and the two ends of the spring 7 abut against the housing 1 and the heat collection plate 2-2 respectively, forming a pressure. In the compressed state, during installation, the second connecting rod 6 is inserted into the housing 1 from top to bottom, and is limited by the first limiting plate 6-1 at the top of the second connecting rod 6 contacting the housing 1. The lower end of the second connecting rod 6 is threaded to the mounting plates 2-2-1 on the four sides of the heat collection plate 2-2. Since the spring 7 is in a compressed state at this time, it can press the heat collection plate 2-2 onto the heat conduction pad 2-1 downwards on one hand, and upwards on the other hand, so that the housing 1 is always in close contact with the limiting plate, avoiding contact with the aluminum fins 2-3, and ensuring that the internal structure of the housing 1 is not damaged.

[0037] Furthermore, two sets of arc-shaped grooves 1-4 are symmetrically arranged on both sides of the housing 1, and the first connecting rod 5 is located within the arc-shaped grooves 1-4; the first connecting rod 5 is fixed in the gap between adjacent heat dissipation fins of the radiator, thereby fixing the housing 1 to the radiator; the first connecting rod 5 is a screw, with a second limiting plate 5-1 threaded to the upper end and an adjusting block 5-2 threaded to the lower end. The adjusting block 5-2 is a cuboid, and its width is smaller than the width of the gap between adjacent heat dissipation fins of the radiator, facilitating the adjustment block 5-2 to enter the gap; when the housing 1 is... When the body 1 is installed on the radiator, after adjusting the length of the first connecting rod of the adjusting block 5-2 extending into the radiator, the adjusting block 5-2 is set vertically and extends into the gap between adjacent heat dissipation fins of the radiator together with one end of the first connecting rod 5. Then, the first connecting rod 5 is rotated so that the adjusting block 5-2 is set horizontally and locked in the gap for positioning. Then, the position of the second limiting plate 5-1 on the first connecting rod 5 is adjusted so that the second limiting plate 5-1 is pressed against the upper end face of the housing 1, thereby fixing the housing 1 onto the radiator.

[0038] In addition, such as Figure 10 As shown, several auxiliary heat dissipation devices can also be connected side by side, linked by arc-shaped grooves 1-4 and the first connecting rod 5, to meet the heat dissipation needs of radiators of various sizes. In this case, the controller controls the operation of several fans through the fan hub.

[0039] Furthermore, a dustproof net (not shown in the figure) is provided at the air inlet 1-2 to prevent impurities from entering the housing 1 and affecting heat exchange.

[0040] The working process of this auxiliary heat dissipation device for the radiator is as follows:

[0041] First, the auxiliary heat dissipation device is installed on the corresponding radiator. When the temperature sensor 4 detects that the temperature of the radiator has reached the starting temperature of the fan 1-3, the controller 3 controls the fan 1-3 to start. The cooler air enters the interior of the housing 1 through the air inlet 1-2 on the housing 1. At the same time, the heat on the radiator is conducted to the heat collector plate 2-2 through the heat conduction pad 2-1. Then the heat on the heat collector plate 2-2 is conducted to the aluminum fins 2-3, which have a larger surface area and stronger heat dissipation. The heat is exchanged with the cooler air. Then the hot air is evenly transported to the indoor space by the fan 1-3 in the form of convection. During this process, the controller adjusts the fan speed in real time according to the radiator temperature monitored by the temperature sensor to ensure the stability of the indoor temperature.

[0042] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
