Heating system

Abstract

The present invention discloses a heating system, comprising a linear pipeline layout substrate and a reversing pipeline layout substrate, both of which are embedded with pipeline positioning structures. The peripheral area of ​​the heating pipeline circumferentially wrapped by the pipeline positioning structure per unit length is greater than 50% and less than or equal to 65% of the peripheral area of ​​the heating pipeline per unit length. The use of a pipeline installation structure with a high coverage rate can improve heating efficiency. At the same time, because the pipeline installation structure adopts an embedded structure between the substrate, the bonding strength between the two is several times that of previous solutions. Even if the pipeline expands thermally, it will not separate from the pipeline groove. Previous solutions generally only use installation clips to be clamped in the pipeline groove, which cannot take into account the heat radiation of the entire substrate surface and therefore cannot achieve high heating efficiency. However, the present technical solution can provide efficient heating in areas where efficient heating is required, and effectively release thermal expansion stress in areas where efficient heating is not required.

Description

Technical Field

[0001] The present invention relates to the technical field of heating systems, and in particular to a heating system capable of improving heating efficiency and suitable for special areas such as long and narrow channels / compact areas. Background Art

[0002] Heating systems are primarily categorized by their heating method: low-temperature hot water radiant floor heating (water floor heating) and heating cable radiant floor heating (electric floor heating). Most existing interiors utilize low-temperature hot water wall / floor radiant heating. This method uses hot water, typically no higher than 60°C, as the heat medium, which circulates through heating pipes to heat the walls / floor, then delivers heat to the interior through radiation and convection.

[0003] Existing heating systems generally have pipeline grooves reserved on the heating modules. Most pipeline grooves adopt a U-shaped structure. After the pipeline is installed, the pipeline will inevitably expand due to the hot water it transports. If the heat is not dissipated in time, the thermal expansion of the pipeline will continue to increase, causing the stress of the pipeline structure to increase, and the pipeline will easily bend. Since the top resistance of the pipeline is small, the pipeline will bend upward, and the contact area between the pipeline and the pipeline groove will decrease. The pipeline will continue to bend upward and eventually lift up the floor above it. In addition, the traditional pipeline groove adopts a U-shaped structure, which makes the pipeline wrapping rate at most 50%, making the heating efficiency unsatisfactory. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the prior art, and therefore a heating system is proposed to improve the heating efficiency of the heating system, and can be applied to special areas such as long and narrow channels and compact areas.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A heating system includes a base plate for linear pipeline routing and a base plate for reversing pipeline routing. Both the base plate and the base plate are embedded with pipeline positioning structures. The peripheral area of ​​the heating pipeline wrapped circumferentially by the pipeline positioning structures per unit length is greater than 50% and less than or equal to 65% of the peripheral area of ​​the heating pipeline per unit length. Indoor heating systems are generally installed using straight sections and reversing sections between the straight sections. However, if a traditional U-shaped pipeline groove is used, the above-mentioned problem will occur. However, using a pipeline installation structure with a high coverage rate can improve heating efficiency. Furthermore, because the pipeline installation structure and the base plate are embedded in a structure, the bonding strength between the two is several times greater than that of previous solutions. Even if the pipeline expands thermally, it will not separate from the pipeline groove. Previous solutions generally only use mounting clips to clamp the installation clips within the pipeline groove, which cannot take into account the heat radiation of the entire base plate surface and therefore cannot achieve high heating efficiency. However, the present technical solution can provide efficient heating in areas requiring efficient heating and effectively release thermal expansion stress in areas not requiring efficient heating.

[0007] Based on the solution of the present application, the following improvements are made: the pipeline positioning structure includes a covering section located at the bottom and used to wrap the pipeline, a limiting section located above the covering section and integrally provided with the covering section, and a heat radiation panel covering the corresponding substrate. The limiting section and the covering section are retracted inward at the junction to form a closing area. High heating conversion efficiency is achieved through the high coverage rate of the covering section. At the same time, because the limiting section at the closing area limits the heating pipeline wrapped by its covering section, after the limiting treatment, even if the heating pipeline expands and falls out of the groove due to heat, the plate will not be warped or bulged.

[0008] Based on the solution of the present application, the following improvements are made: the two limiting sections are respectively arranged at the top ends of the covering section. The pipeline positioning structure adopts the limiting sections arranged on both sides of the covering section, which can achieve the above effect in an ideal state.

[0009] Based on the solution of the present application, the following improvements have been made: the limiting segment is provided at either end of the top of the covering segment, and the other end of the covering segment is a vertical straight segment transition. A pipeline positioning structure using a limiting segment at one end of the covering segment can also achieve the above effect, but the effect is slightly inferior to the corresponding effect achieved by a structural design with two limiting segments.

[0010] Based on the solution of the present application, the following improvements are made: the corresponding radii of the limiting section and the covering section are equal, or the radius of the limiting section is 0.2 to 2.0 mm larger than the radius of the covering section. The former can ensure the adaptability of the pipeline and, based on the structural performance of the pipeline after installation, can achieve the optimal pipeline structural stability under the premise of equal radii. The latter can also ensure the adaptability of the pipeline and, based on the structural performance of the pipeline after installation, this structural design can effectively improve the pipeline structural stability, but the effect is slightly inferior to that of the same radius.

[0011] Based on the solution of the present application, the following improvement is made: the width of the top opening of the coating section accounts for 89% to 94% of the corresponding diameter of the coating section. This method can take into account the adaptability installation of the heating pipeline and the structural stability and reliability after installation, effectively ensuring the effect of the high coverage rate pipeline installation.

[0012] Based on the solution of the present application, the following improvements are made: the pipeline reversing layout substrate includes an inner reversing distribution section and an outer reversing distribution section, the inner reversing distribution section is a circular arc section with an angle greater than 180°, the outer reversing distribution section includes a transverse section, a longitudinal section, and a turning section for connecting the transverse section and the longitudinal section, and the pipeline positioning structure is installed on the transverse section and the longitudinal section. This design is for compact area heating. Since the pipeline spacing in the existing solution is mostly more than 150mm, if this solution is used for heating in a compact area, the heating efficiency of the area near the side road after the pipeline is installed will be very low, and the structural stress of the curved pipeline after thermal expansion will be equivalent to several times that of the conventional installation form, which is very prone to the phenomenon of de-grooving and plate knocking. Therefore, this technical solution solves this problem. By making a large bend inside and a small bend outside at the bend, it can not only ensure efficient heating but also prevent the phenomenon of de-grooving and plate knocking at the reversing point.

[0013] On the basis of the present application, the following improvements are made: pipeline positioning structures are evenly spaced on the pipeline straight-line layout substrate, and the spacing between two adjacent pipeline positioning structures is 150mm to 500mm. The solution here is for special areas with long and narrow passages. Since most of the areas are indoor entrances, the heating demand is not large. Most of the existing solutions use a heating design structure with full coverage of heat radiation, which consumes a certain amount of heat in areas that do not originally require special heating. Therefore, intermittent heat dissipation + positioning treatment is adopted. If the spacing between the pipeline positioning structures is too large, the stress after the thermal expansion of the pipeline cannot be effectively released. Although the heat loss at this location can be reduced, there is a risk of the pipeline being out of the groove. If the pipeline positioning structure is too dense, the heat loss is too large, which increases the user's cost of use. Therefore, the above solution is designed.

[0014] Based on the solution of this application, the following improvements are made: the pipeline reversing layout base plate is installed at both ends of the pipeline straight line layout base plate. The pipeline reversing layout base plate includes reversing segment 1, reversing segment 2, and an arc transition segment for connecting reversing segment 1 and reversing segment 2. The pipeline positioning structure is installed on reversing segment 1 and reversing segment 2. This technical solution is an improvement for the connecting reversing area of ​​long and narrow channels and areas with heating needs, as well as the area where the heating source connects to the ground / wall. Since the bends in this area also have the problems existing in the above-mentioned bends, this structure is provided here to solve these problems.

[0015] Based on the solution of this application, the following improvements are made: the linear pipeline layout base plate and the reversing pipeline layout base plate are connected by a mortise and tenon structure. This allows the various base plates in the heating system to be connected to form a whole, so that the pipelines are on the same horizontal plane without any height difference, making the heating more uniform.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0036] Example 1

[0037] like Figures 1 to 6 、 Figures 13 to 18A heating system is shown, including a pipeline straight-line layout substrate 100 and a pipeline reversing layout substrate 200, both of which are provided with pipeline grooves, the cross-section of which needs to be adapted to the pipeline positioning structure 300, and the pipeline straight-line layout substrate 100 and the pipeline reversing layout substrate 200 are both embedded with pipeline positioning structures 300. The outer area of ​​the pipeline positioning structure 300 circumferentially wrapped around the heating pipeline per unit length is greater than 50% and less than or equal to 65% of the outer area of ​​the heating pipeline per unit length. When installing an indoor heating system, straight sections and switching sections between straight sections are generally used. However, if a traditional U-shaped pipeline groove is used, the above problems will occur. However, the use of a pipeline installation structure 320 with a high coverage rate will improve the heating efficiency. At the same time, since the pipeline installation structure and the substrate are embedded in a structure, the bonding strength between the two will be several times that of the previous solution. Even if the pipeline expands due to heat, it will not separate from the pipeline groove. The previous solution generally only uses installation clips to be set in the pipeline groove, which cannot take into account the heat radiation of the entire substrate surface. To achieve higher heating efficiency, this technical solution can provide efficient heating to areas that require efficient heating. Specifically, the pipeline positioning structure 300 with a high coverage rate can ensure the high-efficiency conversion of the pipeline to the heat radiation aluminum panel. The entire pipeline positioning structure 300, including the heat radiation aluminum panel covering the entire substrate, can be used to wrap the pipeline and form an inlaid structure that is compatible with the pipeline groove. Specifically, it can effectively release thermal expansion stress in areas that do not require efficient heating. This solution is suitable for general heating areas, and the installation distance between two adjacent pipelines is generally about 150mm.

[0038] Example 2

[0039] like Figures 7 to 12 As shown, the following improvements are made on the basis of the above embodiment: the pipeline positioning structure 300 includes a covering section 310 located at the bottom and used to wrap the pipeline, a limiting section 320 located above the covering section 310 and integrally provided with the covering section 310, and a heat radiation panel 330 covering the corresponding substrate. The limiting section 320 and the covering section 310 are retracted inward at the junction to form a closed area. The heat radiation panel 330 is made of 0.3mm thick aluminum plate, and the limiting section 320 and the covering section 310 are made of arc section structure. Figures 7 to 12 As shown, the use of aluminum material can take into account both cost and heat radiation efficiency, and achieve high heating conversion efficiency through the high coverage rate of the covering section 310. At the same time, since the limiting section 320 at the closing area will limit the heating pipeline wrapped by its covering section 310, after the limiting treatment, even if the heating pipeline expands and falls out of the groove due to heat, the plate will not be warped or bulged.

[0040] Example 3

[0041] like Figure 7 、 9As shown in Figures 11 and 12, based on the above embodiment, the following improvements are made: two limiting sections 320 are provided, one at each end of the top of the covering section 310. The pipeline positioning structure 300 uses limiting sections 320 provided on both sides of the covering section 310 to achieve the above-mentioned effect in an ideal state. When the pipeline transports hot water and experiences thermal expansion, the top of the covering section 310 is supported outward, causing the opening of the covering section 310 to have an outward expansion tendency. Due to the presence of the base plate and limiting sections 320, the base plate and limiting sections 320 cooperate with the pipeline to maintain a stable state, and the contact surface between the two does not change, thereby maintaining its heating efficiency.

[0042] Example 4

[0043] like Figure 8 、 10 12 , unlike Example 3, the limiting segment 320 is provided at one end of the top of the covering segment 310, and the other end of the covering segment 310 is a vertical straight segment transition. The pipeline positioning structure 300 employing a limiting segment 320 at one end of the covering segment 310 can also achieve the aforementioned effect, though the effect is slightly inferior to that achieved by a structural design with two limiting segments 320.

[0044] Example 5

[0045] like Figure 9 and Figure 10 As shown, based on any of the above embodiments, the following improvements are made: the radii corresponding to the limiting section 320 and the covering section 310 are equal. This ensures the adaptability of the pipeline and, based on the structural performance of the pipeline after installation, the pipeline structural stability can be optimized under the premise of equal radii.

[0046] Example 6

[0047] like Figure 9 and Figure 10 As shown, different from Example 5, the radius size corresponding to the limiting section 320 is 0.2 to 2.0 mm larger than the radius size corresponding to the covering section 310, preferably 0.5 mm, which can also ensure the adaptability of the pipeline. At the same time, according to the structural performance of the pipeline after installation, this structural design can effectively improve the stability of the pipeline structure, but the effect is slightly inferior to that when the radius size is the same.

[0048] Example 7

[0049] Based on any of the above embodiments, the following improvements are made: the width of the top opening of the cladding section 310 accounts for 89% to 94% of the corresponding diameter of the cladding section 310. The cladding section diameter used in our test samples is 16.3mm, and the top opening widths are 14.60mm, 15.18mm, and 15.80mm. This method can take into account both the adaptability and installation of the heating pipeline and the structural stability and reliability after installation, effectively ensuring the effect of high-coverage pipeline installation. It also meets the requirement that the circumferential area of ​​the heating pipeline wrapped by the pipeline positioning and installation structure 300 per unit length is greater than 50% and less than or equal to 65% of the peripheral area of ​​the heating pipeline per unit length.

[0050] Example 8

[0051] like Figure 3 、 Figure 4 、 Figure 14 、 Figure 18 As shown, based on any of the above embodiments, the following improvements are made: the pipeline reversing layout base plate 200 includes an inner reversing distribution section 210 and an outer reversing distribution section 220, the inner reversing distribution section 210 is a circular arc section with an angle greater than 180 degrees, and the outer reversing distribution section 220 includes a transverse section 221, a longitudinal section 222, and a turning section 223 for connecting the transverse section 221 and the longitudinal section 222. The pipeline positioning structure 300 is installed on the transverse section 221 and the longitudinal section 222, and the turning section 223 can also be provided. If the inner reversing distribution section 210 is a circular arc section with an angle of 180 degrees, it can only be applied to general heating areas (such as Figure 1 、 Figure 2 、 Figure 13 As shown), this design in this solution is aimed at compact area heating. Since the pipeline spacing in the existing solution is mostly more than 150mm, if this solution is used for compact area heating, the heating efficiency of the area near the side channel after the pipeline is installed will be very low, and the structural stress of the curved pipeline after the pipeline expands due to heat will be equivalent to several times that of the conventional installation form, which is very likely to cause the phenomenon of de-grooving and plate knocking. Therefore, this technical solution is used to solve this problem. By making a large bend on the inside and a small bend on the outside at the bend, it can not only ensure efficient heating but also prevent the phenomenon of de-grooving and plate knocking at the reversing point. The pipeline spacing can be controlled at about 100mm.

[0052] Example 9

[0053] like Figure 5 and Figure 6As shown, based on any of the above embodiments, the following improvements are made: pipeline positioning structures 300 are evenly spaced on the pipeline linear layout substrate 100, and the spacing between two adjacent pipeline positioning structures 300 is 150mm to 500mm. The pipeline positioning structures 300 of our experimental samples are 40mm long and 220mm apart, 45mm long and 280mm apart, and 50mm long and 340mm apart. This solution is designed for special areas of long and narrow passages. Since these areas are mostly indoor entrances, heating requirements are not high. Most existing solutions use a full-coverage heat radiation heating design structure, which consumes a certain amount of heat in areas that do not require special heating requirements. Therefore, intermittent heat dissipation + positioning treatment is adopted. If the spacing between the pipeline positioning structures 300 is too large, the stress caused by thermal expansion of the pipeline cannot be effectively released. Although this can reduce heat loss in this area, there is a risk of pipeline derailment. If the pipeline positioning structures 300 are too dense, heat loss is too large, increasing user costs. Therefore, the above design is adopted.

[0054] Example 10

[0055] like Figure 5 As shown, based on any of the above embodiments, the following improvements are made: the pipeline reversing layout substrate 200 is installed at both ends of the pipeline straight line layout substrate 100; the pipeline reversing layout substrate 200 includes a reversing segment 1 230, a reversing segment 240, and an arc transition segment 250 for connecting the reversing segment 1 230 and the reversing segment 2 240; the pipeline positioning structure 300 is installed on the reversing segment 1 230 and the reversing segment 2 240; the arc transition segment 250 can also be provided. The above structure has the same effect as the outer reversing distribution segment 220, so it will not be described in detail. This technical solution is an improvement made for the connection and reversing areas of long and narrow channels and areas with heating requirements, as well as the connection area between the heating source and the ground / wall. Since the bends there also have the problems existing in the above bends, this structure is provided here to solve the problems.

[0056] Example 11

[0057] like Figure 13 、 Figure 14 、 Figure 15 、 Figure 16 As shown, based on any of the above embodiments, the following improvements are made: the linear pipeline layout base plate 100 and the reversing pipeline layout base plate 200 are connected by a mortise and tenon structure. This allows the various base plates in the heating system to be connected to form a whole, so that the pipelines are on the same horizontal plane without any height differences, resulting in more uniform heating.

The replacement may be a replacement of a portion of a structure, device, or method step, or it may be a complete technical solution.
