[0002] In common building heating systems, the heat source mainly relies on urban central heating, supplemented by decentralized heating or independent heating. The radiator mainly uses water heating steel tube radiators, and some new types of radiators such as floor water pipe heating, carbon crystal electric heating, air source heat pump heating, graphene electric heating, etc. have also been partially applied.

[0003] The heating radiator is the most important client-related system in the heating system, but the current heating radiator has the problem of low heating efficiency.

[0004] In view of this, this application is specifically proposed. Utility Model Content

[0005] In consideration of the above problems, this application is proposed. According to one aspect of this application, a heating radiator is provided, including: a heat dissipation plate core, heat dissipation fins, and a heat source; the number of heat dissipation fins is multiple, and the multiple heat dissipation fins are arranged on at least one side of the heat dissipation plate core, and the heat dissipation fins distributed on the same side of the heat dissipation plate core are evenly arranged on the heat dissipation plate core; the heat source is connected to the heat dissipation plate core to transfer the heat provided by the heat source to the external environment through the heat dissipation plate core and the heat dissipation fins.

[0006] Exemplarily, the multiple heat dissipation fins are symmetrically distributed on both sides of the heat dissipation plate core.

[0007] Exemplarily, for the heat dissipation fin group distributed on any one side of the heat dissipation plate core, the two outermost heat dissipation fins in the heat dissipation fin group both extend outward in a direction away from the heat dissipation plate core, and the extending ends of the two heat dissipation fins are connected to each other to form a convection heat dissipation cover, and the convection heat dissipation cover forms an air-restricted space with the two outermost heat dissipation fins and the heat dissipation plate core in the extending direction of the heat dissipation fins.

[0008] Exemplarily, the outer surface of the convection heat dissipation cover is coated with an infrared radiation heat dissipation coating.

[0009] Exemplarily, the heat dissipation plate core is composed of multiple flat heat pipes connected in sequence, and the heat dissipation fins located on the same flat heat pipe are parallel to each other.

[0010] Exemplarily, the heat dissipation fins on the flat heat pipe and the flat heat pipe are of an integrated structure.

[0028] In the following description, a large number of details are provided to enable a thorough understanding of the present utility model. However, those skilled in the art can understand that the following description only relates to the preferred embodiments of the present utility model, and the present utility model can be implemented without one or more such details. In addition, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described.

[0029] As described above, the current heating radiators have the problem of low heating efficiency. For example, in the currently common central heating system, due to the annual shutdown of heating, the air in the radiator pipes may be blocked, the hot water flow may not be smooth, the heating may be uneven, affecting the overall energy efficiency of the heating system; the air source heat pump heating system has complex equipment, low heating efficiency in winter, poor heating effect, and even cannot achieve the heating effect; the floor heating system is blocked due to water scaling, affecting the performance and even the life of the heating system, etc. In view of this, the present application provides a heating radiator, which has a simple overall structure and high heat dissipation and heating efficiency. The specific structure of this heating radiator is described in detail below.

[0030] Refer to Figure 1-4 , the embodiments of the present application provide a heating radiator, which includes: a heat dissipation plate core 1, heat dissipation fins 4 and a heat source 3; the number of heat dissipation fins 4 is multiple, and the multiple heat dissipation fins 4 are arranged on at least one side of the heat dissipation plate core 1, and the heat dissipation fins 4 distributed on the same side of the heat dissipation plate core 1 are evenly arranged on the heat dissipation plate core 1; the heat source 3 is connected to the heat dissipation plate core 1 to transfer the heat provided by the heat source 3 to the external environment through the heat dissipation plate core 1 and the heat dissipation fins 4.

[0031] In the solution of this example, the heat dissipation fins 4 distributed on the same side of the heat dissipation plate core 1 can be called a group of heat dissipation fins 4. In some embodiments, the arrangement direction of the heat dissipation fins 4 on the heat dissipation plate core 1 can be horizontal or vertical. InFigure 3 In the illustrated embodiment, the X direction is the horizontal direction and the Y direction is the vertical direction. In this embodiment, the arrangement direction of the heat dissipation fins 4 on the heat dissipation plate core 1 is the horizontal direction, that is, they are evenly arranged in sequence along the horizontal direction.

[0032] Optionally, the length of the heat dissipation fins 4 can be set according to actual needs. In a specific embodiment of the present application, the length of the heat dissipation fins 4 can be in the range of [15 mm, 25 mm].

[0033] In some embodiments of this example, multiple heat dissipation fins 4 can be evenly distributed on one side of the heat dissipation plate core 1. Of course, they can also be respectively distributed on both sides of the heat dissipation plate core 1. The number of heat dissipation fins 4 distributed on both sides of the heat dissipation plate core 1 can be the same or different.

[0034] In the solution of this example, the heat source 3 is connected to the heat dissipation plate core 1. This connection method includes but is not limited to welding, plugging, bonding and other methods. The specific connection method can be selected according to actual needs and will not be elaborated. The connection position between the heat dissipation plate core 1 and the heat source 3 can be any end of the heat dissipation plate core 1, for example, the upper end, the lower end, the left end, the right end, etc. In the Figure 1 illustrated embodiment, the lower end of the heat dissipation plate core 1 is connected to the heat source 3.

[0035] It can be understood that according to the heat transfer principle, for the low-temperature range where the household radiator is located, in the enclosed space, since the air is quickly heated by the radiator, the air needs to quickly dissipate the heat carried by the radiator to the space. In a limited space, when the air temperature difference exceeds a certain temperature, natural convection with a certain speed and flow rate can be formed by itself to strengthen convective heat dissipation, thereby improving the heat dissipation efficiency of the radiator. For the same heating capacity, the volume and raw materials of the radiator can be reduced, and the cost of the radiator can be further reduced. In the above solution of this example, the heat in the heat source 3 is dissipated to the external environment through the heat dissipation plate core 1 and the heat dissipation fins 4 distributed on the heat dissipation plate core 1. On the one hand, by setting the heat dissipation fins 4, the heat dissipation area of the radiator can be increased. On the other hand, the space between the heat dissipation fins 4 is quickly heated by the heat dissipation fins 4 and the heat dissipation plate core 1, and a temperature difference is formed between it and the external environment, and then natural convection with a certain speed and flow rate will be formed, and the heat in the control is quickly dispersed to the external environment through convective heat dissipation. Thus, it helps to improve the heating and heat dissipation efficiency. In short, the heating radiator structure of this solution is simple and has a high heating and heat dissipation efficiency.

[0036] As Figure 4As shown, in some embodiments of the present application, a plurality of heat dissipation fins 4 are symmetrically distributed on both sides of the heat dissipation plate core 1. This distribution method helps to further improve the heat dissipation efficiency. Moreover, since the heat dissipation fins 4 are evenly distributed on both sides of the heat dissipation plate core 1, heat can be evenly dissipated to the external environment on both sides of the heat dissipation plate core 1, which helps to improve the heating uniformity.

[0037] As Figure 6-9 shown, in some embodiments of the present application, for the group of heat dissipation fins 4 distributed on either side of the heat dissipation plate core 1, the two outermost heat dissipation fins 4 in the group of heat dissipation fins 4 both extend outward in a direction away from the heat dissipation plate core 1, and the extending ends of the two heat dissipation fins 4 are connected to each other to form a convective heat dissipation cover 2. The convective heat dissipation cover 2 forms an air-restricted space with the two outermost heat dissipation fins 4 and the heat dissipation plate core 1 in the extending direction of the heat dissipation fins 4.

[0038] It can be understood that the convective heat dissipation cover 2 includes the parts where the two heat dissipation fins 4 extend outward (which can be called the extending parts), and the connecting part for connecting the two extending ends. The convective heat dissipation cover 2 can enclose a restricted space with the two outermost heat dissipation fins 4 and the heat dissipation plate core 1, and only the upper and lower sides of this space communicate with the outside. Taking Figure 1 the structure shown as an example for illustration, the extending direction of the heat dissipation fins 4 can be called the front-back direction. Due to the setting of the convective heat dissipation cover 2, the heat of the heat dissipation plate core 1 cannot be directly dispersed to the external environment from the front and back sides, and due to the enclosure of the two outermost heat dissipation fins 4, most of the heat of the heat dissipation plate core 1 (a small part of the heat can be directly dispersed to the external environment from the outer sides of the two outermost heat dissipation fins 4) also cannot be directly dispersed to the external environment from the left and right sides. In this case, only the upper and lower sides communicate with the outside.

[0039] In the solution of this embodiment, the outermost heat dissipation fins 4 extend outward in a direction away from the heat dissipation plate core 1. In some implementation solutions, the extending structure and the heat dissipation fins 4 can be an integrated structure, that is, the convective heat dissipation cover 2 can be formed by integrally drawing the two heat dissipation fins 4. In some other implementation solutions, a formed metal can be connected to the two outermost heat dissipation fins 4. The shape of the outer side surface of the convective heat dissipation cover 2 can be selected according to actual needs. For example, the shape of the outer side surface of the convective heat dissipation cover 2 can be a trapezoid as shown in Figure 6 , 7 shown, or it can be a rectangle as shown in Figure 8 shown. Of course, in some embodiments not shown in the present application, the shape of the outer side surface of the convective heat dissipation cover 2 can also be an arc surface.

[0040] According to the above technical solution, by providing the convection heat dissipation cover 2, an air convection restricted space can be formed with the two outermost heat dissipation fins 4 and the heat dissipation plate core 1. Due to the heat dissipation of the heat dissipation plate core 1 and the heat dissipation fins 4, the air in this air convection restricted space can be quickly heated, increasing the temperature difference between the temperature in this space and the external environment, thereby forming enhanced natural convection and further enhancing the heat dissipation effect.

[0041] In some embodiments of the present application, an infrared radiation heat dissipation coating is coated on the outer surface of the convection heat dissipation cover 2. The specific material of this infrared radiation heat dissipation coating can be selected according to actual needs and will not be elaborated. In the solution of this embodiment, by coating the infrared radiation heat dissipation coating, the heat dissipation effect of the heating radiator can be strengthened, and the heating efficiency can be further improved.

[0042] In some embodiments of the present application, colors can be sprayed on the outer surface of the convection heat dissipation cover 2 according to aesthetic requirements to form an aesthetic decoration effect. For example, in the embodiment where the above-mentioned convection heat dissipation cover 2 is integrally drawn by the heat dissipation fins 4, the surface can be further sprayed with a heat dissipation coating (such as an infrared radiation heat dissipation coating) and colors according to aesthetic requirements to form an aesthetic decoration effect.

[0043] In some embodiments of the present application, when using formed metal as the convection heat dissipation cover 2, the material of the convection heat dissipation cover 2 can be decorative metal. In a specific embodiment, metal aluminum with painted or patterned designs on the surface can be used to form the convection heat dissipation cover 2.

[0044] Optionally, the heat dissipation plate core 1 can be composed of at least one flat heat pipe. For example, in Figure 6-8 the shown embodiment, the heat dissipation plate core 1 is composed of one flat heat pipe. This flat heat pipe can be integrally drawn from metal aluminum, which helps to improve the overall aesthetic degree and structural strength.

[0045] In some embodiments of the present application, as Figure 9 shown, the heat dissipation plate core 1 is composed of a plurality of flat heat pipes connected in sequence, and the heat dissipation fins 4 located on the same flat heat pipe are parallel to each other. In some implementation solutions of this embodiment, the plurality of flat heat pipes can be arranged in a straight line (as Figure 9 ). In some solutions not shown in this embodiment, a certain angle can be formed between two mutually connected heat dissipation plate cores 1, and this angle is less than 180°.

[0046] In some solutions not shown in this embodiment, when the heat dissipation plate core 1 is composed of a plurality of flat heat pipes, the plurality of flat heat pipes can be arranged parallel to each other.

[0047] In the above technical solution, the heat dissipation plate core 1 is composed of a plurality of flat heat pipes. Thus, it helps to increase the heat dissipation area, and can play a good heating effect in a relatively large heating environment to be heated.

[0048] In some embodiments of the present application, the heat dissipation fins 4 on the flat heat pipe and the flat heat pipe are of an integral structure. This way can improve the overall structural strength and has a relatively high overall aesthetic degree.

[0049] As Figure 5 shown, in some embodiments of the present application, a plurality of protrusions 101 are arranged on one side of the inner wall of the heat dissipation plate core 1 along the height direction, and the arc chamfer angle of the protrusion 101 is greater than the wetting angle of the medium in the heat dissipation plate core 1.

[0050] It can be understood that in the embodiment where the heat dissipation plate core 1 is composed of one flat heat pipe, the inner wall of the heat dissipation plate core 1 is the inner side wall of the flat heat pipe. In the embodiment where the heat dissipation plate core 1 is composed of a plurality of flat heat pipes, the inner wall of the heat dissipation plate core 1 is the inner side wall of each flat heat pipe.

[0051] The above solution can be conducive to the evaporation of the medium in the heat dissipation plate core 1 by arranging the protrusions 101 on the inner wall of the heat dissipation plate core 1 and making the arc chamfer angle of the protrusions 101 greater than the wetting angle of the medium in the heat dissipation plate core 1, thereby being conducive to improving the heat conduction efficiency of the heat dissipation plate core 1, reducing heat loss, and further being conducive to the heating efficiency.

[0052] In some embodiments of the present application, as Figure 1-2 shown, the heat source 3 is a heat-carrying pipe, and a heat medium is provided in the heat-carrying pipe, and the end of the heat dissipation plate core 1 is inserted into the heat-carrying pipe.

[0053] The insertion depth of the end of the heat dissipation plate core 1 into the heat-carrying pipe can be selected according to actual needs. In a specific embodiment, the insertion depth can be in the range of [5 mm, 20 mm].

[0054] After the end of the heat dissipation plate core 1 is inserted into the heat-carrying pipe, it can be hermetically connected by welding or bonding to maintain the structural vertical stability and prevent the heat medium in the heat-carrying pipe from leaking out of the heat-carrying pipe. In a specific embodiment of the present application, after the end of the heat dissipation plate core 1 is inserted into the heat-carrying pipe, it can be leak-free welded by brazing or argon arc welding.

[0055] The heat medium in the heat-carrying pipe can be selected according to actual needs. For example, it can be hot water.

[0056] The above technical solution uses the heat-carrying pipe as the heat source 3 to supply heat to the heat dissipation plate core 1, with a simple overall structure, convenient installation, and high heat transfer efficiency.

[0057] In some embodiments of the present application, a heating device for supplying a heat medium to the energy-carrying pipe is connected to the end of the energy-carrying pipe. The heating device may specifically be a boiler hot water pipeline or a municipal hot water pipeline. The heat source 3 in this embodiment has flexible selection and can be well applied in areas with central heating and areas using traditional boiler heating.

[0058] In some embodiments of the present application, the heat source 3 includes at least one electric heating sheet, and the electric heating sheet is attached to the heat dissipation plate core 1. In a specific embodiment of the present application, the electric heating sheet can be attached to the heat dissipation plate core 1 through a heat-conducting adhesive, and the attachment height can be within the range of [5 mm, 25 mm].

[0059] The above solution uses the electric heating sheet as the heat source 3. In this case, the heating radiator can be directly powered on to heat the external environment. The overall structure of the device is simple, the installation is convenient, and the applicable range is wide.
