Description

Technical Field

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

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

[0003] A heat pump is an energy-saving device that transfers low-level heat sources, such as air, water or soil heat energy, to high-level heat sources driven by high-level energy, generally electrical energy or thermal energy, thereby providing heating services for production and life. It does not generate heat, but transfers external energy to the interior of the house, which can reduce energy consumption and improve energy utilization.

[0004] At present, in heating systems that use heat pumps as heat sources, most of them use pre-buried floor heating pipes to transfer heat to the room. However, with the increasing awareness of energy conservation among users and the limitations of some usage scenarios, radiator products that can be turned on and off at any time are increasingly attracting the attention and use of users.

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

[0006] However, considering that the maximum water outlet 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, making it impossible for existing products to take into account both energy utilization and heating effect requirements. Summary of the invention

[0007] The object of the present invention is to provide a low-temperature radiator to solve the problem that the prior art cannot take into account both energy utilization and heating effect requirements.

The first waterway plate portion and the second waterway plate portion are connected by a plurality of connecting pipes, and the opposite sides of the first waterway plate portion and the second waterway 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 such a configuration, radiating fins for heat dissipation are installed between the first water channel plate portion and the second water channel plate portion, so that the heat of the hot water inside the two water channel plate portions is fully transferred to the air, and the heat is used 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 the heat dissipation of traditional radiators through natural convection of air leads to slow heat dissipation and poor heating effect. The present 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, and is combined with an energy-saving heat pump as a heat source, thereby solving the problem that the prior art cannot take into account both heating effect and energy utilization rate.

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

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

[0013] Furthermore, a hook assembly is provided, which includes an upper clamp and a lower clamp respectively connected to a connecting rod and its upper and lower ends, the upper clamp can be snap-connected to the heat dissipation top cover, and the lower clamp can be snap-connected to 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, the inner sides of the first water channel plate portion and the second water channel plate portion are both provided with connecting holes, 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.

[0017] Furthermore, the side cover plate is equipped with a control mechanism electrically connected to the single axial flow fan, and the control mechanism includes a display screen, a PLC control board, an indoor temperature sensor and a water temperature sensor. The display screen can display the indoor temperature and water temperature respectively detected by the indoor temperature sensor and the water temperature sensor, and the PLC control board can control the opening and closing of the single axial flow fan through a preset program.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] In the current heating system, the radiator transfers heat to the indoor air through natural convection. The hot water temperature requirement of the radiator is relatively high, usually the water temperature must be above 70°C to ensure the indoor heating effect. For the low-temperature water supply using a heat pump as a heat source, it is difficult to meet the indoor heating needs. It is difficult to take into account the requirements of heating effect and energy utilization rate. In order to solve the problems existing in the prior art, this embodiment provides a low-temperature radiator to improve energy utilization rate and heating effect at the same time.

[0039] The low-temperature radiator provided in this embodiment is matched with a heating system using a heat pump as a heat source, such as Figure 1 and 2 As shown, the main heating surface is a first waterway plate portion 100 and a second waterway plate portion 110 which are arranged opposite to each other in the front and back. The heating water is installed inside the two waterway plates, and the two waterway plates are connected by connecting pipes. Figure 3 As shown, a three-way pipe 140 can be used to connect the two, and a connecting hole 101 is opened on the inner side of the two; a heat dissipation fin part 200 and a fan assembly 300 that are detachably connected to the first waterway plate part 100 and the second waterway plate part 110 are provided between the first waterway plate part 100 and the second waterway plate part 110, as shown in FIG. Figure 5 As shown, the first waterway plate portion 100 and the second waterway 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 with the inner side surfaces of the two to facilitate heat transfer. The shape is preferably a repeatedly arranged "J"-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 part 200 has two upper and lower parts, 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 cold and hot 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, and 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.

[0040] Preferably, a heat dissipation top cover 400 is provided above the heat sink in this embodiment, and 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 for hot air to be blown upwards. 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 air flow. The heat dissipation hole 401 is preferably in an inverted water drop shape. Both sides of the heat dissipation hole 401 are streamlined to reduce the resistance of air flow. The heat dissipation top cover 400 is detachably connected, for example, a matching piece is provided on the top between the first waterway plate portion 100 and the second waterway plate portion 110, such as Figure 8As 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.

[0041] 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 6 Engaged 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.

[0042] In this embodiment, a hydraulic distributor 150 is provided between the three-way pipe 140 and the connecting hole 101. Figure 4 As shown, a plurality of through holes are evenly arranged 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.

[0043] Considering the different installation positions 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 assembly 500 is provided for easy installation. Fig. 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. In this way, assembly and disassembly are 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 member and the mounting hole 511. The mounting member, such as a bolt, has high stability and low cost through threaded connection.

[0044] In order to facilitate the intelligent operation of the radiator, a control mechanism 600 is installed on the side cover plate 120, which can control the opening and closing of the single axial flow fan 320. Preferably, the control mechanism 600 includes a display screen 610, a PLC control board 620, an indoor temperature sensor 630 and a water temperature sensor 640. Fig.10 and 11As shown, the indoor temperature sensor 630 can detect the temperature of the indoor air, the water temperature sensor 640 can detect the temperature of the hot water in the radiator, and the detected indoor temperature and water temperature are displayed on the display screen 610. The PLC can set a preset program to control the opening and closing of the single axial flow fan 320.

[0045] Specifically, the thermoelectric valve of the radiator can be controlled to open when the water temperature is less than the indoor temperature by 2°C; the thermoelectric valve can be controlled to close when the water temperature is lower than the indoor temperature; or the thermoelectric valve can be automatically closed after the water temperature is detected to be lower than the set value; the single axial flow fan 320 can be automatically opened when the water temperature is higher than the set value, otherwise it can be closed. In addition, the wind speed can be adjusted through the touch display screen 610, for example, n wind speed gears can be set for self-adjustment, or automatic adjustment can be selected. Of course, the adjustable parameters are not limited to the wind speed, and other parameters and ranges can be adjusted according to the setting program. The principle of the PLC control board 620 can be clearly understood by those skilled in the art, and its setting method will not be described in detail here.

[0046] Through the cooperation of the fan assembly 300 and the heat dissipation fin part 200, this device greatly improves the heat dissipation efficiency, 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.
