[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0036] like Figure 1 As shown, this utility model discloses an annular PTC heater, including an annular PTC heater body 1 and heat dissipation components 2 disposed on the inner and outer annular surfaces of the PTC heater body 1. The PTC heater body 1 adopts the prior art, which includes at least an aluminum tube seat and a PTC heating core. This is the prior art and will not be described in detail here.
[0037] The heat dissipation assembly 2 includes a heat dissipation corrugated strip 3, a punch plate 4, and a bent edge plate 5. The punch plate 4 and the bent edge plate 5 are respectively disposed on opposite sides of the heat dissipation corrugated strip 3. The heat dissipation corrugated strip 3 is formed by bending a sheet-like metal plate into a continuous V shape multiple times. At least the corrugated surface of the heat dissipation corrugated strip 3 is provided with a heat dissipation part 6 in the heat dissipation assembly 2.
[0038] like Figure 2 and Figure 11 As shown, when a heat dissipation part 6 is provided on the corrugated surface of the heat dissipation corrugated strip 3, the heat dissipation part 6 can be a heat dissipation through hole 8 or a raised reinforcing rib 7.
[0039] like Figure 2As shown, when the heat dissipation part 6 is a heat dissipation through hole 8, it is respectively set on the corrugated surface of the heat dissipation corrugated strip 3 to improve the heat dissipation efficiency, especially when the wind speed is high (above 4m / s), the effect is more obvious, and it has the following setting forms:
[0040] like Figure 5 As shown, multiple rectangular heat dissipation holes 8 are provided on each corrugated surface, which can be spaced apart along the width direction of the corrugated surface.
[0041] like Figure 6 As shown, a rectangular heat dissipation hole 8 is provided on each corrugated surface, which can occupy at least half of the surface area of the corrugated surface; of course, its shape can also be set as follows: Figure 7 The circle shown, or as Figure 9 The polygon shown is, for example, a hexagon.
[0042] like Figure 7 As shown, multiple heat dissipation holes 8 are arranged in an array on each corrugated surface. The heat dissipation holes 8 are circular and arranged in at least two rows and two columns; of course, their shape can also be set as follows: Figure 8 The polygon shown is, for example, a hexagon.
[0043] like Figure 3 and Figure 4 As shown, based on the above structure, an extended edge 9 can be provided on one side of the heat dissipation hole 8. The extended edge 9 partially blocks the heat dissipation hole 8. The extended edge 9 is set off from the heat dissipation hole 8 so as to protrude from the heat dissipation hole 8 and form a guide plate. By setting its guiding direction, heat can be guided through the extended edge 9 and form turbulence, further improving the heat dissipation effect.
[0044] like Figure 11 and Figure 12 As shown, when the heat dissipation part 6 is a raised reinforcing rib 7, it increases the heat dissipation area to improve the compressive strength of the corrugated material and improve the heat dissipation efficiency. The effect is more obvious when the wind speed is high (above 4m / s). It is set on the corrugated surface of the heat dissipation corrugated strip 3, and the raised direction is the same. It has the following configuration forms:
[0045] like Figure 12 As shown, multiple rectangular reinforcing ribs 7 are provided on each corrugated surface, which can be spaced apart along the width direction of the corrugated surface.
[0046] like Figure 13 As shown, a rectangular reinforcing rib 7 is provided on each corrugated surface, which can occupy at least half of the surface area of the corrugated surface; of course, its shape can also be set as follows: Figure 15 The circle shown, or as Figure 17 The polygon shown is, for example, a hexagon.
[0047] like Figure 14 As shown, multiple reinforcing ribs 7 are arranged in an array on each corrugated surface. The reinforcing ribs 7 are circular and arranged in at least two rows and two columns; of course, their shape can also be set as follows: Figure 16 The polygon shown is, for example, a hexagon.
[0048] like Figure 18 As shown, when the punch plate 4 is provided with a heat dissipation part 6, the heat dissipation part 6 is a heat dissipation through hole 8. The heat dissipation through holes 8 are spaced apart along the length direction of the punch plate 4. The heat dissipation through holes 8 are square holes. Of course, they can also be set as circular holes (e.g., Figure 19 (As shown), it can also be set as follows Figure 20 As shown, heat dissipation holes 8 are provided at intervals on the long sides of opposite sides of the punch plate 4, and the heat dissipation holes 8 penetrate through the edge of the punch plate 4.
[0049] like Figure 21 As shown, when the curved edge plate 5 is provided with a heat dissipation part 6, the heat dissipation part 6 is a heat dissipation through hole 8. The heat dissipation through holes 8 are spaced apart along the length direction of the curved edge plate 5. The heat dissipation through holes 8 are square holes. Of course, they can also be set as circular holes (e.g., Figure 22 (As shown), it can also be set as follows Figure 23 As shown, heat dissipation holes 8 are provided at intervals on the long sides of opposite sides of the curved edge plate 5, and the heat dissipation holes 8 penetrate through the edge of the curved edge plate 5.
[0050] In this utility model, a cutting gap 10 is provided between two adjacent heat dissipation through holes in the curved edge plate 5. Figure 21 , Figure 22 and Figure 23 As shown in the figure, it is used to cut a gap in the curved plate 5 to achieve the overall bending of the heat dissipation component 2.
[0051] This invention improves heat dissipation efficiency by providing heat dissipation parts on the heat dissipation corrugated strip 3, punch plate 4 and / or bent edge plate 5.
