Description

Technical Field

[0001] This utility model relates to the field of PTC heater technology, and in particular to a double-sided corrugated PTC heater. Background Technology

[0002] Traditional PTC heaters typically employ fixed-size frame structures, resulting in poor installation adaptability and difficulty in flexibly adapting to equipment such as sterilizers and drying ovens of varying sizes. Furthermore, the heat transfer efficiency of existing PTC heaters is limited by their structural design, leading to uneven heat dissipation and a lack of effective adjustment mechanisms. This necessitates customized models, increasing production costs and maintenance complexity. While some designs attempt to enhance stability through rigid structures, this sacrifices flexibility and fails to meet the demands of diverse application scenarios.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1 to 5 This utility model provides a double-sided corrugated PTC heater, which includes a serpentine copper tube 1 and a side plate 2.

[0028] In the embodiments of this utility model, please refer to Figures 1 to 5 There are two side plates 2, and two symmetrically distributed elastic corrugated steel sheets 3 are fixedly installed between the two side plates 2. The side plates 2 and the elastic corrugated steel sheets 3 form a frame structure for installing the serpentine copper tube 1. Multiple PTC heating elements 5 are fixedly installed on the inner walls of the two side plates 2. The upper and lower ends of the frame structure are provided with docking plate groups 4. The two docking plate groups 4 form a cover plate structure for sealing the upper and lower ends of the frame structure.

[0029] The docking plate assembly 4 includes a main board 41 and an adjusting plate 42. The connecting end of the main board 41 has an insertion cavity. The connecting end of the adjusting plate 42 is fixedly installed with an insertion plate 43, which is inserted into the insertion cavity of the main board 41 and slidably connected to the insertion cavity. The side wall of the main board 41 has a threaded through hole communicating with the insertion cavity, and a threaded fastening screw 44 is inserted into the threaded through hole. The outer plate head of the main board 41 is fixedly connected to the inner wall of the side plate 2 on one side of the frame structure, and the outer plate head of the adjusting plate 42 is fixedly connected to the inner wall of the side plate 2 on the other side of the frame structure. The serpentine copper tube 1 is fixedly connected to the side plate 2 connected to the main board 41 through the frame.

[0030] It should be noted that by sliding the insertion plate 43 on the adjustment plate 42 into or out of the insertion cavity opened on the main plate 41, the length of the cover plate structure formed by the main plate 41 and the adjustment plate 42 can be effectively adjusted. After adjustment, tighten the fastening screw 44 to fix the insertion plate 43 in the main plate 41. Since the elastic corrugated steel sheet 3 is an elastic structure, the elastic corrugated steel sheet 3 can be stretched or compressed by adjusting the length of the cover plate structure. Therefore, the frame structure can be effectively adjusted in length.

[0031] When installing a PTC heater inside a disinfection cabinet or drying oven, if the cabinet or drying oven is too large or too small, the staff can quickly adjust the frame structure to adapt it to different cabinet or drying oven structures.

[0032] Among them, the PTC heating core 5 is a semiconductor heating core or a resistive heating core, so that the heat emitted by the PTC heating core 5 can heat the serpentine copper tube 1.

[0033] Furthermore, the elastic corrugated steel sheet 3 has multiple evenly distributed through holes 3a, which are designed to allow air to pass through.

[0034] Furthermore, both the main board 41 and the side plate 2 are provided with slide rails 45, and the end face of the elastic corrugated steel sheet 3 is inserted into the slide rail 45 and slidably connected to the slide rail 45, which improves the stability of the elastic corrugated steel sheet 3 during adjustment.

[0035] The serpentine copper tube 1 has an inlet 11 and an outlet 12 fixedly installed at its two ends. The main board 41 and the adjustment plate 42 located above the frame structure are both provided with waist-shaped outlets 4a. The inlet 11 and the outlet 12 extend out of the waist-shaped outlets 4a provided on the main board 41 and the adjustment plate 42, respectively. The waist-shaped outlets 4a design allows the inlet 11 and the outlet 12 to slide freely during the adjustment process, simplifying the pipeline connection process.

[0036] In this application, the length of the frame structure can be flexibly adjusted by the sliding fit design of the elastic corrugated steel sheet 3 and the docking plate group 4 to adapt to the installation requirements of equipment of different sizes, significantly reducing the customization cost. The serpentine copper tube 1 and the double-sided distributed PTC heating core 5, together with the through hole 3a of the elastic corrugated steel sheet 3, realize uniform heat diffusion and air convection, and avoid local overheating.

[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
