Description

Technical Field

[0001] The invention belongs to the technical field of skirting board heating, and more specifically, particularly relates to an energy-saving skirting board heating device. Background Art

[0002] Heating refers to the design of buildings and cold-proof heating devices to obtain appropriate temperatures inside buildings. At present, most northern regions use floor heating or radiator heating. These two types of heating equipment cannot meet the following requirements at the same time: aesthetics; easy maintenance; instant heating; balanced room temperature in different areas; rapid heating of room temperature, etc. However, the pipelines of floor heating age quickly, and the thermal expansion and contraction effect causes the floor to deform, crack, and loosen with the increase of years. The construction volume is large, and the pipelines are prone to aging and leakage over time. The maintenance is difficult and expensive. The heating speed is slow, and it usually takes 8-12 hours to heat the temperature to a comfortable temperature. The slow heating speed cannot be turned on and off at will, resulting in high energy consumption. Against the background of advocating energy conservation and emission reduction and increasingly high aesthetic requirements, new heat dissipation methods that integrate heating functions into skirting boards have appeared in Europe, the United States, and my country in recent years.

[0003] Existing skirting heating equipment can be heated by electricity or circulating hot water. However, the existing skirting heating power is low, and it loses its heat dissipation ability after being blocked by home furnishings, and cannot heat the room temperature to a more comfortable temperature. In addition, the existing skirting heating is difficult to install and takes a long time to install. It cannot be installed using standard original parts. It requires on-site interception, tapping and other processing steps, which seriously reduces the construction efficiency. Due to the lack of standardization, it is easy to leak. The thick thickness (3.5-6cm) affects home furnishings. The use of a large amount of copper processing results in excessive costs. The heat dissipation power can only be adjusted by water temperature, resulting in too low heating power and increased heating energy consumption. Summary of the invention

[0016] 1. The skirting board heating equipment is formed by one-piece profile. After secondary processing of the aluminum alloy profile, an air flow channel is formed inside the profile, and hot water of 65 to 80 degrees enters the water channel.

[0032] Example:

[0033] As attached Figure 1 To Attachment Fig.10 As shown:

[0034] The present invention provides an energy-saving skirting heating device, comprising a main radiator 101, a wall mounting port 110 is provided on one side of the main radiator 101, a radiator main pipe 102, a water inlet pipe 503 and a water return pipe 603 are provided in the main radiator 101, the water inlet pipe 503 is connected to the radiator main pipe 102 through a water supply tee 504, the water return pipe 603 is connected to the radiator main pipe 102 through a water return tee 604, side sealing plates 701 are provided on both sides of the main radiator 101, and a side of the main radiator 101 is provided. A fan mounting port 107 is provided, and a cross-flow fan 108 is arranged in the fan mounting port 107. An external air inlet 103 is provided on one side of the main radiator 101, an internal air outlet 104 and an internal air inlet 105 are provided on the other side of the main radiator 101, an external air outlet 106 is provided on the top of the main radiator 101, a diverter plate body 302 and a plurality of heat dissipating fins 109 are arranged inside the main radiator 101, a filter plate body 202 is provided on one side of the main radiator 101, and a back plate body 402 is provided on the other side of the main radiator 101.

[0035] The main radiator 101 can be installed on the wall through the wall installation port 110, and the installation method adopts the hanging buckle method. The radiator main pipe 102, the water inlet pipe 503 and the return pipe 603 in the heating equipment cooperate with the water supply tee 504 and the return tee 604 to form an "S"-shaped water channel. Hot water flows in from the water inlet pipe 503, flows into the radiator main pipe 102 through the water supply tee 504, and then flows out from the return pipe 603 through the return tee 604, so that the main radiator 101 is heated and the cold air is preliminarily heated. Side sealing plates 701 are arranged on both sides of the main radiator 101 to prevent dust from entering the main radiator 101. In order to facilitate the installation of the heating equipment, the main radiator 101 is provided with a fan installation port 107 for installing a cross-flow fan 108. The cross-flow fan 108 is operated to draw air in from the external air inlet 103, and the filter plate body 202 filters the air to prevent external impurities from entering. The air is separated from the air outlet of the cross-flow fan 108 and the internal air outlet 104 by the diverter plate body 302, so that the air flows in a directional manner to avoid cross-flow. The air is fully in contact with the radiator main pipe 102 to heat up, and then is further heated by the heat dissipation fins 109 and then slowly discharged from the external air outlet 106, thereby further heating the indoor space.

[0036] like Figure 1 , 2As shown, three groups of mounting holes 702 are provided on the side sealing plate 701, one group of mounting holes 702 cooperates with the radiator main pipe 102, both ends of the water supply tee 504 are inserted into two groups of mounting holes 702 of one group of side sealing plates 701, both ends of the water return tee 604 are inserted into two groups of mounting holes 702 of another group of side sealing plates 701, one end of the water inlet pipe 503 is inserted into one group of mounting holes 702 of one group of side sealing plates 701, and one end of the water return pipe 603 is inserted into one group of mounting holes 702 of another group of side sealing plates 701.

[0037] The side sealing plate 701 is provided with an installation hole 702 to provide an installation space for the water supply tee 504 and the water return tee 604, and to install and fix the water inlet pipe 503 and the water return pipe 603, so as to prevent the positions of the water inlet pipe 503 and the water return pipe 603 from shifting during use, and to avoid the cold and hot cross-flow caused by the direct contact between the water inlet pipe 503 and the water return pipe 603 and the main radiator 101, thereby affecting the heat dissipation, thereby effectively improving the stability and installation flexibility of the heating equipment.

[0038] like Figure 2 , 9 As shown, a fan fixing plate 801 is provided on one side of the cross flow fan 108, and the fan fixing plate 801 is connected to one side of the main radiator 101 by bolts, and the cross flow fan 108 is arranged between the fan fixing plate 801 and the main radiator 101. The cross flow fan 108 is fixed by the fan fixing plate 801, so that its installation is more stable and efficient, and it is convenient to disassemble the cross flow fan 108, thereby improving the efficiency of construction.

[0039] like Figure 2 , 8 As shown, a manifold guide rail 301 is provided inside the main radiator 101, a first mounting bracket 303 is provided on one side of the manifold body 302, and the manifold body 302 is connected to the main radiator 101 by being clamped on the manifold guide rail 301 through the first mounting bracket 303. A filter plate guide rail 201 is provided on one side of the main radiator 101, and second mounting brackets 203 are provided on both sides of the filter plate body 202, and the filter plate body 202 is connected to the main radiator 101 by being clamped on the filter plate guide rail 201 through the second mounting bracket 203. A back plate guide rail 401 is provided on one side of the main radiator 101, and two groups of third brackets 403 are provided on one side of the back plate body 402, and the back plate body 402 is connected to the main radiator 101 by being clamped on the back plate guide rail 401 through the two groups of third brackets 403.

[0040] The diverter plate guide rail 301 is provided for installing the diverter plate body 302, and the diverter plate body 302 is inserted into the diverter plate guide rail 301 for installation. Similarly, the filter plate body 202 and the back plate body 402 are also installed in the form of insertion installation, so that the diverter plate body 302, the filter plate body 202 and the back plate body 402 can be quickly installed and disassembled, and no other tools are required during the installation process, thereby improving the installation efficiency.

[0041] like Figure 7 , 8 As shown, two groups of first tube holder brackets 501 are arranged at the bottom inner side of the main radiator 101, and the first water pipe brackets 502 are both arranged in the two groups of first tube holder brackets 501, and the two ends of the water inlet pipe 503 are respectively passed through the two groups of first water pipe brackets 502; two groups of second tube holder brackets 601 are arranged at the top inner side of the main radiator 101, and the second water pipe brackets 602 are both arranged in the two groups of second tube holder brackets 601, and the two ends of the return pipe 603 are respectively passed through the two groups of second water pipe brackets 602.

[0042] A first pipe seat bracket 501 and a second pipe seat bracket 601 are provided to respectively install a first water pipe seat 502 and a second water pipe seat 602. The first water pipe seat 502 and the second water pipe seat 602 are also installed in an interlaced manner, and the installation is efficient and quick. The first water pipe seat 502 is provided to install an inlet pipe 503, and the second water pipe seat 602 is provided to install a return pipe 603, thereby improving the stability of the heating equipment for pipeline installation, preventing the pipeline from being offset and causing damage to the pipeline, and effectively isolating the inlet pipe 503 and the return pipe 603 from the main radiator 101 to avoid heat loss.

[0043] The water inlet pipe 503, the water return pipe 603, the water supply tee 504 and the water return tee 604 are all made of common pipe fittings on the market. The main radiator 101 is an integral profile formed by extrusion of aluminum alloy. The back plate body 402, the diverter plate body 302 and the filter plate body 202 can all be made of aluminum and galvanized sheet. The water inlet pipe 503 and the water return pipe 603 can both be made of common pipes on the market (such as stainless steel pipes and aluminum-plastic pipes), and the water supply tee 504 and the water return tee 604 can be combined with common joints on the market, thereby avoiding the problem of difficult matching of skirting accessories. In addition, in some embodiments, the water inlet pipe 503, the water return pipe 603, the water supply tee 504 and the water return tee 604 may also use professionally customized special pipe fittings to further enhance the operational stability; the main radiator 101 is formed by extrusion of aluminum alloy, which has better heat dissipation and reduces energy waste. The aluminum back plate body 402, the diverter plate body 302 and the filter plate body 202 are more practical and galvanized plates can be used to further reduce costs.

[0044] The specific usage and function of this embodiment are as follows:

[0045] The skirting heating equipment is formed by one-piece profile. After secondary processing of the aluminum alloy profile, an air flow channel is formed inside the profile. Hot water of 65 to 80 degrees enters the water channel. The hot water enters the water supply tee 504 from the water inlet pipe 503 and flows to the radiator main pipe 102, and then flows from the return tee 604 to the return pipe 603, thereby heating the main radiator 101. The main radiator 101 radiates the room temperature to the outside through the outer surface. At the same time, the convection heating process is started. The cold air is filtered by the filter plate body 202 and then enters the main radiator through the external air inlet 103. 101 starts to heat up inside, and under the action of the cross-flow fan 108, the air enters the internal air outlet 104 through the manifold body 302, and then passes through the radiator main pipe 102 to heat the air. The heated air contacts the heat dissipation fins 109 through the internal air inlet 105 for further heating, and then flows out from the external air outlet 106 to be dispersed indoors for heating. The skirting heating equipment is not afraid of being blocked by furniture, and greatly improves the heating power. When the room temperature is 20 degrees and the water temperature is 75 degrees, the heating power can be increased from 120 watts / m of the existing skirting heating to 1070 watts / m. The heating capacity is 3-10 times that of the existing skirting heating equipment. It can be temporarily closed when there is no one in the room, and temporarily opened when heating is needed to quickly increase the room temperature, thereby saving more energy consumption.

[0046] The skirting heating equipment is mainly composed of an interlaced structure, the manifold body 302 is inserted into the manifold guide rail 301, the back plate body 402 is inserted into the back plate guide rail 401, the filter plate body 202 is inserted into the filter plate guide rail 201, and the cross-flow fan 108 is directly placed in the fan installation port 107 for installation. The side sealing plate 701 is installed on both sides of the main radiator 101, and the water inlet pipe 503 is connected to one end of the radiator main pipe 102 through the water supply tee 504, and the return pipe 603 is connected to the other end of the radiator main pipe 102 through the return tee 604. This skirting heating equipment can be made into a standard size of 3.1 cm thick and 2.5 meters, 2 meters, 1.5 meters or 0.5 meters in length. It can be installed by matching and combining different lengths of skirting heating equipment on site according to the length of the wall. There is no need for on-site processing steps such as on-site interception and tapping, so that the skirting heating equipment is safe and fast to install, and the construction efficiency is improved.
