Description

Technical Field

[0001] This utility model relates to a PTC heater, and more particularly to a PTC heater core holder and a PTC heater. Background Technology

[0002] With the widespread application of PTC heaters, especially in the cleaning market (such as in robotic vacuum cleaners and floor scrubbers), there is a need for miniaturized PTC hot water modules to save space, reduce costs, improve overall system stability, and simultaneously possess safety and reliability. Existing products are relatively large in size and use a single-channel water pipe, resulting in a small contact area between the heating surface of the PTC heating element and the water, leading to lower thermal efficiency. Furthermore, the use of plastic seals at both ends compromises the structural stability and waterproofing. Summary of the Invention

[0003] The purpose of this invention is to provide a PTC heater core holder and a PTC heater, and the technical problem to be solved is to improve the heat dissipation effect.

[0004] To solve the above problems, the present invention adopts the following technical solution: a PTC heater core holder, including a body, the body including at least one row and two columns of core tubes and an expanded edge, the core tubes are flat tubular and have two opposing heat-conducting surfaces, the heat-conducting surfaces on the same side of the core tubes in each row are located on the same plane, one end of the core tube is open and the other end is closed, the heat-conducting surface is perpendicular to the closed surface, so that the heat-conducting surface forms a vertical surface perpendicular to the closed surface.

[0005] Furthermore, the body comprises two rows and two columns of core tubes.

[0006] Furthermore, the core tube and the expanded edge are integrally formed aluminum parts.

[0007] Furthermore, the core tube has a length of <100mm, a width of <50mm, and a thickness of 5mm <10mm.

[0008] Furthermore, the core tube has a length of <100mm, a width of <50mm, and a thickness of 5mm <10mm.

[0009] This utility model also discloses a PTC heater, including a PTC heating core and a PTC heater core seat. The PTC heating core is disposed in the cavity of the core tube, and the heating surface and the heat-conducting surface of the PTC heating core are in close contact.

[0010] Furthermore, the PTC heating core is composed of multiple PTC heating elements, two electrode plates, and insulating paper. The PTC heating elements are laid flat between the two electrode plates, and the insulating paper is wrapped around the electrode plates.

[0011] Compared with the prior art, this utility model sets at least one row and two columns of core tubes, and sets the heat-conducting surface of the core tubes to be perpendicular to the closed surface. After the PTC heating component is installed, the heating surface of the PTC heating component and the heat-conducting surface of the core tube can be closely attached, so that the heat can be directly dissipated to the outside through the heat-conducting surface, thereby improving the heat dissipation effect.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0017] like Figures 1 to 3 As shown, this utility model discloses a PTC heater core holder, including a body 1. The body 1 includes at least one row and two columns of core tubes 2 and an extended edge 3. The core tubes 2 are flat tubes with two opposing heat-conducting surfaces 21. The heat-conducting surfaces 21 on the same side of each row of core tubes 2 are located on the same plane. The upper end of the core tube 2 is open and the lower end is a closed surface 22. The heat-conducting surface 21 is perpendicular to the closed surface 22, so that the heat-conducting surface 21 forms a vertical surface perpendicular to the closed surface. This allows the heat-conducting surface 21 to be completely and tightly fitted with the heating surface of the PTC heating core 4 when pressed, thus eliminating the need for wedge-shaped parts to press the PTC heating core 4 against the heat-conducting surface 21. This not only reduces the use of accessories but also improves the heat dissipation effect.

[0018] In this utility model, the core tube 2 and the expanded edge 3 are integrally formed cast aluminum parts. The expanded edge 3 is arranged around the outside of the core tube 2, and a gap is provided between the two core tubes 2. (Viewed from the side) Figure 3 The overall shape is T-shaped.

[0019] This utility model is mainly aimed at small PTC heaters, such as those with overall dimensions in the range of 150mm (length) x 120mm (width) x 50mm (height).

[0020] like Figure 2 and Figure 3As shown, in this utility model, the structure is suitable for PTC heater core holders of the following dimensions, wherein the length L1 of the core tube 2 is less than 100 mm, the width L2 is less than 50 mm, and the thickness L3 is less than 10 mm.

[0021] This invention uses a vertical surface that is perpendicular to the closed surface to make the heat-conducting surface of the core tube fit tightly with the heating surface of the PTC heating core through a pressing process. This eliminates the need for wedges, reducing costs. The arrangement of at least one row and two columns not only improves heat dissipation but also significantly reduces the thickness of the core tube and water tank, meeting the requirements for miniaturized PTC heaters.

[0022] like Figure 1 As shown, in the first embodiment of this utility model, the main body 1 consists of two core tubes 2 arranged in one row and two columns.

[0023] like Figure 4 As shown, in the second embodiment of this utility model, the main body 1 is composed of four core tubes 2 in two rows and two columns.

[0024] like Figures 1 to 3 As shown, this utility model also discloses a PTC heater. Only the part during heating is shown in the figure, and its water tank is omitted here. The PTC heater includes a water tank (not shown in the figure), a PTC heating core 4 and the aforementioned PTC heater core seat. The PTC heating core 4 is disposed in the cavity of the core tube 2. After the core tube 2 is pressed, the heating surface of the PTC heating core 4 is tightly attached to the heat-conducting surface 21.

[0025] like Figure 3 As shown, the PTC heating core 4 consists of multiple PTC heating elements 41, two electrode plates 42, and insulating paper 43. The PTC heating elements 41 are laid flat between the two electrode plates 42, and the insulating paper 43 is wrapped around the electrode plates 42. As can be seen from the figure, the flat laying adopts a multi-row and multi-column method.
