Description

Technical Field

[0001] The utility model relates to the technical field of heating and ventilation, in particular to a prefabricated floor heating module. Background Art

[0002] As society progresses, people's demands for a higher quality of life continue to rise. Due to their geographical location and climate, northern China and parts of southern China require indoor heating to ensure comfort in winter. Compared to air conditioning, radiant floor heating is gaining popularity due to its uniform heating, relative energy savings, and improved comfort.

[0003] The existing technology usually uses the dry installation method of floor heating. The floor heating coil needs to heat the floor first, and then the floor is transferred to the room by radiation and conduction. However, the heat conduction process of transferring heat to the floor is slow, resulting in a slow indoor temperature rise rate and a long thermal effect time when residents use floor heating, which results in a poor human experience. Utility Model Content

[0004] In view of the above analysis, the embodiment of the present invention aims to provide a prefabricated floor heating module to solve the problems of slow indoor heating speed, long thermal effect time and poor human experience of existing dry floor heating.

[0005] The purpose of this utility model is mainly achieved through the following technical solutions:

[0006] A floor heating prefabricated module is covered with a floor, comprising a floor heating prefabricated module body, a ventilation pipe and an air duct;

[0007] The ventilation pipe is arranged on the main body of the floor heating prefabricated module, and a plurality of the ventilation pipes are evenly arranged;

[0008] The air duct is located at the lower part of the main body of the floor heating prefabricated module; the air duct includes a transverse air duct and a longitudinal air duct; the transverse air duct and the longitudinal air duct intersect at the ventilation pipe;

[0009] Heat dissipation holes are provided at positions of the floor corresponding to the ventilation pipes.

[0010] Furthermore, the transverse air duct runs through the transverse length of the main body of the prefabricated floor heating module, and the longitudinal air duct runs through the longitudinal length of the main body of the prefabricated floor heating module.

[0011] Furthermore, it also includes a supporting structure; the supporting structure is arranged on the upper surface of the main body of the floor heating prefabricated module.

[0012] Furthermore, a plurality of the support structures are provided; the support structures are arranged in a rectangular array.

[0013] Furthermore, arc-shaped grooves are provided on opposite sides of the support structures of two adjacent rows to form channels through which the floor heating coils can pass.

[0014] Furthermore, the wall surface of the arc-shaped groove is a spiral structure, a wave structure or a sawtooth structure, so as to increase the contact area between the floor heating coil and the channel.

[0015] Furthermore, the width of the mouth of the arc-shaped groove is smaller than the diameter, which is used to limit the position of the floor heating coil after it is embedded in the arc-shaped groove.

[0016] Furthermore, the heat dissipation holes are a plurality of small holes.

[0017] Furthermore, two adjacent sides of the floor heating prefabricated module body are provided with protrusions, and the other two adjacent sides of the floor heating prefabricated module body are provided with grooves; the protrusions and grooves between adjacent floor heating prefabricated module bodies can be plugged into each other.

[0018] Furthermore, the protrusion or groove is a T-shaped structure.

[0019] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0020] (1) Compared with the prior art, the present invention sets a ventilation duct on the floor heating prefabricated module, and the ventilation duct is connected to the air duct, which is used to send the preheated fresh air to the heat dissipation holes on the floor and further dissipate it into the room. Since the wall thickness of the ventilation duct is very thin and fits tightly with the floor heating coil, the fresh air in the duct can be more fully heated when passing through the ventilation duct, forming natural convection in the room, realizing the organic combination of radiation, conduction and convection of floor heating heat, quickly increasing the heating speed, improving the utilization rate of floor heating heat, shortening the thermal effect time of floor heating, and ensuring the temperature comfort of people.

[0021] (2) The utility model is provided with a supporting structure, and a plurality of supporting structures are provided, which are arranged in a rectangular array to form a multi-point support, thereby improving the compressive resistance of the floor heating module and preventing the floor heating module from being dented or damaged after being compressed. Grooves are provided between the supporting structures for passing the floor heating coils. Since the supporting structures are evenly distributed in the floor heating prefabricated module, the spacing between the floor heating coils is uniform, and they are evenly distributed in the floor heating prefabricated module, which can effectively dissipate heat and make the entire floor heating prefabricated module heat up evenly.

[0022] (3) Compared with the existing technology, the present invention sets a spiral structure of the floor heating coil channel wall, and the heat energy is radiated, diffused and transferred from the pipe to the surrounding floor heating prefabricated modules in a spiral manner evenly and efficiently, and then transferred to the air duct and the room, accelerating the heating of the indoor air, making the room reach a comfortable temperature faster, and improving the human experience. At the same time, the arc-shaped groove wall of the spiral structure can make it more convenient and quick to embed the pipe into the arc-shaped groove when laying, and better ensure the position accuracy of the pipe. Since the spiral structure wall has more contact points with the pipe, the channel wall can fix the spiral coil more stably, improving construction efficiency. The wall with a wave structure and a sawtooth structure is a wall that can increase the contact area between the floor heating coil and the channel, and can achieve the same technical effect.

[0023] (4) The width of the mouth of the arc-shaped groove in the present invention is smaller than the diameter, so that the floor heating coil can be automatically fixed and limited after being embedded in the arc-shaped groove, eliminating the need for pipe clamps.

[0024] (5) The heat dissipation holes in the present invention are a number of small holes to prevent debris from entering the air duct under the floor and affecting the blowing effect.

[0025] (6) In the present invention, two adjacent sides of the floor heating prefabricated module body are provided with protrusions, and the other two adjacent sides are provided with grooves. The protrusions and grooves between adjacent floor heating prefabricated module bodies can be plugged into each other. The protrusions and grooves are both T-shaped, which can make the plugging more secure.

[0026] In the present invention, the above-mentioned technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of the present invention will be described in the following content, and some advantages will become apparent from the description or be understood through practice of the present invention. The objectives and other advantages of the present invention can be realized and obtained through the contents particularly pointed out in the text and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0035] A specific embodiment of the present invention is as follows Figure 1 As shown, a floor heating prefabricated module is disclosed, including a floor heating prefabricated module body 101 , a supporting structure 102 , a ventilation pipe 103 and an air duct 104 .

[0036] The main body 101 of the floor heating prefabricated module is made of thermal insulation material, preferably graphite SEPS material.

[0037] The upper surface of the prefabricated floor heating module body 101 is provided with a support structure 102, which is used to support the pressure transmitted by the floor 2 covering the upper portion of the prefabricated floor heating module body 101. In this embodiment, the support structure 102 is configured as a cylinder. As an alternative, the support structure 102 can also be a block or other solid structure. Multiple support structures 102 are provided, arranged in a rectangular array, forming multiple support points. This improves the prefabricated floor heating module 1's resistance to pressure and prevents the prefabricated floor heating module 1 from denting or damage under pressure.

[0038] Furthermore, arcuate grooves 1021 are provided on opposite sides of two adjacent rows of support structures 102. The curvature of the arcuate grooves 1021 points away from the axis of the support structures 102, thereby forming a channel between the two adjacent rows of support structures 102 for the passage of the floor heating coils. Since the support structures 102 are evenly distributed throughout the prefabricated floor heating module, the spacing between the floor heating coils is uniform and evenly distributed throughout the main body 101 of the prefabricated floor heating module, which effectively dissipates heat and ensures a uniform temperature rise throughout the entire prefabricated floor heating module body 101.

[0039] On the other hand, the diameter of the arc groove 1021 is the same as the outer diameter of the floor heating coil, and the mouth width of the arc groove 1021 is smaller than the diameter, so that the floor heating coil can be automatically fixed and limited after being embedded in the arc groove 1021, eliminating the need for pipe clamps.

[0040] In order to further improve the heating temperature and heating speed of the fresh air in the air duct 104, the wall surface of the arc groove 1021 passing through the floor heating coil is set to a spiral structure to increase the contact area between the floor heating coil and the floor heating prefabricated module body 101.

[0041] Compared with the existing technology, this embodiment sets the inner wall of the floor heating coil channel with a spiral structure, and the heat energy is radiated, diffused and transferred from the pipe to the surrounding floor heating prefabricated module body 101 in a spiral manner, and then transferred to the air duct 104 and the room, accelerating the heating of the indoor air, making the room reach a comfortable temperature more quickly, and improving the human body's experience. At the same time, the wall surface of the arc-shaped groove 1021 with a spiral structure can make it more convenient and quick to embed the pipe into the arc-shaped groove 1021 when laying, and better ensure the position accuracy of the pipe. Since the spiral structure wall has more contact points with the pipe, the channel wall can more stably fix the spiral coil, thereby improving construction efficiency.

[0042] As an alternative to this embodiment, the wall surface of the arc-shaped groove 1021 may also be a wave structure, a sawtooth structure or other structures that can increase the contact area between the floor heating coil and the channel.

[0043] Furthermore, the floor heating prefabricated module body 101 is provided with a plurality of ventilation pipes 103, which are evenly arranged in the floor heating prefabricated module body 101. The diameter of the ventilation pipes 103 is the same as the diameter of the support structure 102, the ventilation pipes have a relatively thin wall thickness, and the ventilation pipes 103 are arranged in a rectangular array on the support structure 102.

[0044] like Figure 2 and Figure 3 As shown, the air duct 104 is located at the bottom of the floor heating prefabricated module body 101. Multiple air ducts 104 are provided, including a transverse air duct 104-1 and a longitudinal air duct 104-2. The transverse air duct 104-1 and the longitudinal air duct 104-2 intersect with the ventilation pipe 103. The transverse air duct 104-1 runs the horizontal length of the floor heating prefabricated module body 101, and the longitudinal air duct 104-2 runs the vertical length of the floor heating prefabricated module body 101. It should be noted that the width of the air duct 104 is the same as the diameter of the ventilation pipe 103.

[0045] The floor 2 covers the top of the floor heating prefabricated module 1. The floor 2 is a composite floor 2, which can make the heat diffuse more evenly and quickly, and can ensure the stable performance of the floor 2 at higher temperatures.

[0046] like Figure 4As shown, heat dissipation holes 201 are provided on the floor 2 at locations corresponding to the ventilation ducts 103. Thus, the air duct 104, the ventilation duct 103, and the heat dissipation holes 201 form a complete channel for fresh air to flow through. To prevent debris from entering the air duct 104 below the floor 2 and affecting the airflow, the heat dissipation holes 201 are formed by a plurality of small holes 103.

[0047] During heating, the heat of the geothermal coil can heat the main body 101 of the floor heating prefabricated module quickly. The fresh air enters the main body 101 of the floor heating prefabricated module from the air duct 104, is heated by the main body 101 of the floor heating prefabricated module, and is dissipated through the ventilation pipe 103 to the heat dissipation holes 201 of the floor 2. As a result, the hot air rises and the cold air in the room falls, and the indoor air forms natural convection, realizing the organic combination of the three modes of radiation, conduction and convection of floor heating heat, quickly increasing the heating speed and improving the experience of indoor people.

[0048] Compared with the prior art, in this embodiment, a ventilation duct 103 is provided on the main body 101 of the floor heating prefabricated module. The ventilation duct 103 is connected to the air duct 104 and is used to send preheated fresh air to the heat dissipation holes 201 of the floor 2. The wall thickness of the ventilation duct 103 is very thin and fits tightly with the floor heating coil. The fresh air in the air duct can be more fully heated when passing through the ventilation duct 103 and further dissipated into the room, forming natural convection indoors, realizing the organic combination of the three modes of radiation, conduction and convection of floor heating heat, quickly increasing the heating speed, improving the utilization rate of floor heating heat, shortening the thermal effect time of floor heating, and ensuring the temperature comfort of people.

[0049] Furthermore, two adjacent sides of the floor heating prefabricated module body 101 are provided with protrusions 106, and the other two adjacent sides are provided with slots 105. The protrusions 106 and slots 105 between adjacent floor heating prefabricated module bodies 101 can be plugged into each other. In this embodiment, the protrusions 106 and slots 105 are both T-shaped, which can make the plugging more secure.

[0050] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
