Description

Technical Field

[0001] The utility model relates to the technical field of heating equipment, in particular to a low-temperature radiator. Background Art

[0002] Driven by growing heating demand and clean heating policies, heat pump sales in my country have continued to grow in recent years. Electrification through heat pumps can provide a key lever for decarbonizing heating, contributing to the achievement of energy and climate goals.

[0003] A heat pump is an energy-saving device that uses high-level energy, typically electricity or thermal energy, to transfer heat from low-level heat sources such as air, water, or soil to a higher-level heat source, thereby providing heating services for production and daily life. It does not generate heat, but rather transfers external energy into the home, reducing energy consumption and improving energy efficiency.

[0004] Currently, most heating systems using heat pumps as heat sources use pre-buried floor heating pipes to deliver heat to the interior of the home. However, with increasing awareness of energy conservation and the limitations of certain usage scenarios, radiators that can be turned on and off at will are gaining increasing attention and adoption.

[0005] In the current heating system, since radiators transfer heat to the indoor air through natural convection, high-temperature water needs to be provided to the radiators. The water temperature usually needs to be above 70°C to ensure the indoor heating effect. If the hot water temperature is too low, the indoor heating effect will inevitably be attenuated. In this case, a larger radiator should be installed to meet the designed heating needs.

[0006] However, considering that the maximum outlet water temperature of heat pumps under certain harsh conditions in winter generally does not exceed 55°C, the heating effect cannot meet expectations. Therefore, wall-mounted boilers are often installed as heat sources in radiator heating systems, which have high energy consumption and make it impossible for existing products to take into account the needs of energy utilization and heating effects. Utility Model Content

[0007] The purpose of the utility model is to provide a low-temperature radiator to solve the problem that the existing technology cannot take into account both energy utilization and heating effect requirements.

[0008] To solve the above problems, the utility model first provides a low-temperature radiator, which is matched with a heating system with a heat pump as a heat source, including: a first water channel plate portion and a second water channel plate portion arranged opposite to each other at an interval, with a heat dissipation fin portion and a detachable fan assembly installed between the two, and the fan assembly can blow the air between the first water channel plate portion and the second water channel plate portion from bottom to top, the first water channel plate portion and the second water channel plate portion are connected by a number of connecting pipes, and the opposite sides of the first water channel plate portion and the second water channel plate portion are respectively connected by side cover plates, and a fan switch that can open and close the fan assembly is installed on the side cover plates.

[0009] With this arrangement, heat dissipation fins for heat dissipation are installed between the first water channel plate portion and the second water channel plate portion, which fully transfer the heat of the hot water inside the two water channel plates to the air, and use the heat to heat the cold air into warm air. In addition, a fan assembly is added to blow the air between the two from bottom to top, thereby accelerating the convection of cold and hot air, and improving the problem that traditional radiators dissipate heat through natural convection of air, resulting in slow heat dissipation and poor heating effect. This device enhances convection, improves heat dissipation performance, and enhances heating effect, so that the hot water in the first water channel plate portion and the second water channel plate portion can achieve an ideal heating effect at a lower temperature. Combined with an energy-saving heat pump as a heat source, it solves the problem that the existing technology cannot take into account both heating effect and energy utilization rate.

[0010] Furthermore, a heat dissipation top cover is installed above the first water channel plate portion and the second water channel plate portion. The heat dissipation top cover is provided with a plurality of heat dissipation holes, and the air blown upward by the fan assembly flows into the outside through the heat dissipation holes.

[0011] Furthermore, a detachable fixing part is provided on the heat dissipation top cover, a matching part is provided between the top of the first water channel plate part and the top of the second water channel plate part, and the fixing part is detachably connected to the matching part.

[0012] Furthermore, the opening area of ​​the heat dissipation holes gradually increases from bottom to top.

[0013] Furthermore, a hook assembly is provided, which includes an upper clamp and a lower clamp connected to a connecting rod and its upper and lower ends respectively, the upper clamp can be engaged with the heat dissipation top cover, and the lower clamp can be engaged with the lower end of the first water channel plate portion and / or the second water channel plate portion, and a mounting hole is provided on the connecting rod, which is configured to be detachably connected to the mounting hole through a mounting member, so that the hook assembly is installed at the position to be installed.

[0014] Furthermore, the heat dissipation fin portion includes two upper and lower groups of first heat dissipation fins and second heat dissipation fins that are spaced apart from each other, and the fan assembly is installed between the first heat dissipation fins and the second heat dissipation fins.

[0015] Furthermore, the fan assembly includes a mounting bracket and a plurality of single axial flow fans. The mounting bracket is provided with a plurality of mounting positions, and the single axial flow fans are correspondingly mounted on the mounting positions.

[0016] Furthermore, the connecting pipe is a tee, and connecting holes are provided on the inner sides of the first waterway plate portion and the second waterway plate portion. The two ends of the tee are respectively connected to the corresponding connecting holes, and a hydraulic distributor is provided between the tee and the connecting holes.

[0033] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0034] In the current heating system, the radiator transmits heat to the air in the room in the form of natural convection, and the hot water temperature of the radiator is required to be relatively high, usually above 70℃, so as to ensure the heating effect in the room. For low-temperature water supply using a heat pump as a heat source, it is difficult to meet the heating demand in the room, so it is difficult to meet the requirements of heating effect and energy utilization rate. In order to solve the problems existing in the prior art, the embodiment provides a low-temperature radiator, which simultaneously improves the energy utilization rate and the heating effect.

[0035] The low-temperature radiator provided in the embodiment matches a heating system using a heat pump as a heat source, as shown in Figure 1 and 2 The main heating surface is the first water channel plate part 100 and the second water channel plate part 110 which are oppositely arranged, water for heating is arranged in the two, and the two are connected in communication through a connecting pipe, as shown in Figure 3 The three-way pipe 140 can be used to connect the two, and the communication hole 101 is arranged on the inner side of the two; the heat dissipation fin part 200 and the fan assembly 300 which are detachably connected with the two are arranged between the first water channel plate part 100 and the second water channel plate part 110, as shown in Figure 5As shown, the first water channel plate portion 100 and the second water channel plate portion 110 can be welded by two stamped low carbon steel plates, and the heat dissipation fin portion 200 can be welded on the inner side surfaces of the two, so that the heat dissipation fin portion 200 fits the inner side surfaces of the two to facilitate heat transfer. The shape is preferably a repeated arrangement of the "X" shaped folded surface to increase the surface area and accelerate the heat dissipation efficiency. Preferably, the installation method of the fan assembly 300 is as follows Figure 6 As shown, the heat dissipation fin portion 200 is formed by an upper and lower portion, a first heat dissipation fin 210 and a second heat dissipation fin 220 arranged at intervals, and the fan assembly 300 is installed between the two. The fan assembly 300 can drive the air to flow from bottom to top, accelerate the convection of hot and cold air, improve the heat dissipation efficiency, and greatly improve the heating efficiency; of course, the installation position of the fan assembly 300 is not limited to Figure 6 As shown in the position, the air between the first waterway plate portion 100 and the second waterway plate portion 110 can be blown out from bottom to top; side covers 120 are provided on both sides of the first waterway plate portion 100 and the second waterway plate portion 110 to stably connect the two. The connection method of the side covers 120 is preferably a snap-fit ​​connection, such as Figure 7 As shown, the side cover 120 is detachably connected to both sides of the radiator through the cooperation of the snap-fit ​​parts and the slots, so that the space inside the radiator is enclosed into a relatively closed environment to reduce heat loss. A fan switch for controlling the opening and closing of the fan assembly 300 is provided on one side of the side cover 120, and the fan assembly 300 can be opened and closed according to usage.

[0036] Preferably, a heat dissipation top cover 400 is provided above the radiator in this embodiment. The details of the structure are shown in FIG. Figure 8 As shown, a heat dissipation hole 401 is provided on the heat dissipation top cover 400 to facilitate the upward blowing of hot air. The shape of the heat dissipation hole 401 is narrow at the bottom and wide at the top, that is, the opening area at the bottom is smaller than the opening area at the top, which reduces the internal heat loss without affecting the flow of air. For example, it is in the shape of an inverted water drop. The two sides of the heat dissipation hole 401 are streamlined to reduce the resistance to air flow. The heat dissipation top cover 400 is detachably connected. For example, a matching piece is provided on the top between the first water channel plate portion 100 and the second water channel plate portion 110, such as Figure 8 As shown, a detachable fixing part 410 is provided on the heat dissipation top cover 400, one end of which can pass through the heat dissipation hole 401 and be engaged with the matching part below, so that the heat dissipation top cover 400 is installed on the top. This structure is simple and the assembly and disassembly efficiency is high.

[0037] like Figure 2 and 6 As shown, the fan assembly 300 is composed of a mounting bracket 310 and a plurality of single axial flow fans 320. The mounting bracket 310 can be detachably connected to the heat dissipation fin portion 200, preferably as shown in FIG. Figure 6Engaged on the second heat dissipation fin 220, a plurality of mounting positions are provided on the mounting bracket 310, and each single axial flow fan 320 is correspondingly mounted on the mounting position, and the preferred connection method is threaded connection.

[0038] In this embodiment, a hydraulic distributor 150 is provided between the tee pipe 140 and the connecting hole 101. Figure 4 As shown, a plurality of through holes are evenly provided on the pipe wall of the hydraulic distributor 150, which can ensure that the low-temperature water can be evenly distributed to each water channel, so that the low-temperature water flows evenly in the first water channel plate portion 100 and the second water channel plate portion 110, and the heat is evenly transferred.

[0039] Taking into account the different installation locations of the radiator, when it is installed at a high place, such as on a wall, it needs to be fixed with the help of a fixing structure. In this embodiment, a hook component 500 is provided for easy installation. Figure 9 As shown, the hook assembly 500 is formed by a vertical connecting rod 510 and an upper clamp 520 and a lower clamp 530 connected at its upper and lower ends, wherein the upper clamp 520 is engaged with the heat dissipation top cover 400, and the lower clamp 530 is engaged with the first water channel plate portion 100 or the second water channel plate portion 110. For example, a slot engaged with the upper clamp 520 can be provided on the heat dissipation top cover 400, and a slot engaged with the lower clamp 530 can be provided on the first water channel plate portion 100 or the second water channel plate portion 110. This makes assembly and disassembly very convenient. The specific lengths of the upper clamp 520 and the lower clamp 530 can be set according to the position of the radiator from the mounting surface. A mounting hole 511 is provided on the connecting rod 510, and the radiator can be installed and fixed by cooperating with the mounting hole 511. The mounting parts, such as bolts, have high stability and low cost through threaded connections.

[0040] This device greatly improves the heat dissipation efficiency through the cooperation of the fan assembly 300 and the heat dissipation fin part 200, improves the problem of poor natural convection heating effect of traditional air technology, and reduces the water temperature of heating water. It can also achieve an ideal heating effect in combination with the low-temperature water of the heat pump, reduces energy consumption, improves energy utilization, and solves the defects of the existing technology.
