Description

Technical Field

[0001] The utility model relates to a heater, in particular to an electric heating component and a skirting heater. Background Art

[0002] The skirting board heater products currently used in the market mainly have the following two types of sheet-mounted radiator structures: (1) bolt assembly through pipe fixing type; (2) structural adhesive type. During the heating process of the skirting board heater, due to poor heat dissipation conditions, the heating effect is poor and the power consumption is high.

[0003] The bolt assembly through-tube fixing type generally uses the heat sink to pass through the circular hole through the bolt assembly for perforation connection. The part of the heat sink that contacts the electric heating component is the heat sink thickness surface or the bent connection surface, and its contact area is small. In addition, the gap between the heat sink and the electric heating component is large, and the heat dissipation effect is poor, causing the temperature of the electric heating component to be too high, resulting in poor heating effect of the product. At the same time, due to the large gap between the heat sink and the electric heating tube, the gap will increase after thermal expansion and contraction, resulting in the radiator being unable to achieve the heat dissipation effect, and abnormal noise and other phenomena will also occur.

[0004] However, due to the lack of forced heat dissipation conditions in the product, the temperature of the electric heating component itself is in a dry-burning condition for a long time, and the structural adhesive type is prone to abnormal phenomena such as debonding. Utility Model Content

[0005] The utility model aims to provide an electric heating component and a skirting heater, and the technical problem to be solved is to improve the heat conduction efficiency and increase the service life of the electric heating component.

[0006] In order to solve the above problems, the utility model adopts the following technical solutions: an electric heating component, including a metal tube body and a heating assembly arranged in the metal tube body, the metal tube body includes two opposite heating surfaces, and a sheet-like heat sink with an integral structure with the heating surface is provided on the heating surface, the heat sink is arranged along the length direction of the metal tube body, and the heat sink is arranged at equal distances.

[0007] Furthermore, the metal tube body is provided with a deformation surface that can be deformed under pressure at a position between the two heating surfaces, and a receiving space for receiving the heating component is provided in the metal tube body.

[0008] Furthermore, the heating surface is provided with pressed edges on both side edges of the heat sink.

[0009] Furthermore, the heat sink is perpendicular to the heating surface or is arranged obliquely on the heating surface.

[0010] Furthermore, the cross-sectional shape of the heat sink is linear or arc-shaped.

[0011] Furthermore, a side of the heat sink opposite to the heating surface is straight, arc-shaped or wavy.

[0012] Furthermore, the metal tube body is composed of two symmetrically arranged half metal bodies.

[0013] Furthermore, the two metal bodies are respectively provided with alignment protrusions and alignment grooves.

[0014] The utility model also discloses a skirting heater, which comprises a casing and the electric heating component.

[0015] Furthermore, an air inlet and an air outlet are respectively provided on the upper end surface and the lower end surface of the casing.

[0016] Compared with the prior art, the utility model avoids the problem of low heat conduction efficiency caused by the gap between the heat sink and the metal tube body by setting the heat sink and the metal tube body as an integrated structure, and also avoids the problem of abnormal noise caused by the enlarged gap between the heat sink and the metal tube body due to thermal expansion and contraction during use, thereby improving the service life of the electric heating component.

[0026] The utility model is further described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figures 1 to 4 As shown, the utility model discloses an electric heating component, including a metal tube body 1 and a heating assembly 2 arranged in the metal tube body 1, the cross-sectional shape of the metal tube body 1 is rectangular, but the utility model is not limited thereto, the cross-sectional shape of the metal tube body 1 can also be circular, the metal tube body 1 includes two opposite heating surfaces 3, and a sheet-like heat sink 4 with an integral structure with the heating surface 3 is provided on the heating surface 3, the heat sink 4 is arranged along the length direction of the metal tube body 1, the heat sink 4 is arranged at equal distances, and the heat sink 4 is made on the heating surface 3 by a tooth-cutting process.

[0028] A deformation surface 5 that can be deformed under pressure is provided at a position of the metal tube body 1 between the two heating surfaces 3, and a receiving space 6 for receiving the heating component 2 is provided in the metal tube body 1, so that after the heating component 2 is assembled into the receiving space 6, an external force is applied to the heating surface 3 to cause the deformation surface 5 to deform, thereby achieving close contact between the heating component 2 and the inner wall of the receiving space 6, thereby improving the heat conduction effect and fixing the heating component 2 at the same time.

[0029] like Figure 2 and Figure 4 As shown, pressing edges 8 are provided on both side edges of the heating surface 3 located on the heat sink 4, and the pressing edges 8 extend along the axis of the metal tube body 1, so that the deformation surface 5 can be deformed by pressing the pressing edges 8 on both sides, so as to bring the heating component 2 into close contact with the inner wall of the accommodating space 6, thereby preventing the problem of deformation and damage of the heat sink 4 caused by applying pressure to the heating surface 3 as a whole.

[0030] In the present invention, the heat sink 4 is perpendicular to the heating surface 3 or is arranged obliquely on the heating surface 3 ( Figure 1 and Figure 4 The cross-sectional shape of the heat sink 4 is a straight line ( Figure 1 shown) or arc ( Figure 5 , Figure 6 The side of the heat sink 4 opposite to the heating surface 3 is a straight line ( Figure 2 as shown), curved or wavy.

[0031] In the utility model, the thickness of the heat sink is between 0.2-1.0mm, preferably 0.5mm, the density of the heat sink (the spacing between the heat dissipation surfaces) is between 2-10mm, preferably 5mm; the width of the heat sink is 30-100mm, preferably 40mm, and the height of the heat sink is 20-60mm, preferably 25mm.

[0032] In the present invention, the heating component 2 may be a PTC heating component ( Figure 1-Figure 4 as shown) or electric heating tube ( Figure 5-Figure 7The cross-sectional shape of the accommodating space 6 is adapted to the cross-sectional shape of the heating component 2 .

[0033] The metal tube body 1 is made of aluminum.

[0034] like Figure 8 As shown, the metal tube body 1 is composed of two symmetrically arranged half metal bodies 7, which are connected and fixed by welding.

[0035] like Figure 8 As shown, alignment protrusions 9 and alignment grooves 10 are respectively provided on the two metal bodies 7 to facilitate positioning and fixation by brazing.

[0036] like Fig. 9 As shown, the utility model also discloses a skirting board heater, including a casing 11, in which the above-mentioned electric heating component 14 is arranged, and an air inlet 12 and an air outlet 13 are respectively arranged on the upper end surface and the lower end surface of the casing 11. No fan is arranged in the skirting board heater, and the air heated by the electric heating component is discharged out of the skirting board heater by natural wind convection.

[0037] The utility model forms a heat sink integrally on the heating surface of the metal tube body so that there is no gap between the heat sink and the heating surface of the metal tube body, thereby ensuring the heat conduction efficiency. At the same time, since there is no structural adhesive, the heat sink and the metal tube body will not be separated due to failure of the structural adhesive due to long-term high-temperature operation, thereby improving the service life of the product.
