Description

Technical Field

[0001] This utility model relates to the field of heating tube technology, and belongs to a high-efficiency single-tube heating tube structure for electromagnetic heaters in new energy vehicles. Background Technology

[0002] PTC heaters are common heating devices, but they have certain limitations: High energy consumption and reduced range: PTC heaters directly convert electrical energy into heat energy, resulting in high energy consumption. Size and cost issues: For high-power applications (e.g., above 12kW), traditional PTC heaters require multiple small heaters connected in parallel, leading to bulky size, increased connection points, complex installation, and higher costs. Insufficient voltage adaptability: The upper limit of the operating voltage of traditional PTC ceramic plates is usually 750V, which cannot meet the requirements of the 800V high-voltage platform of new energy vehicles, posing a potential insulation safety hazard. Structural defects: Some PTC heaters use U-shaped aluminum tubes or compressed structures, which can easily lead to increased water resistance, water pipe deformation, and leakage risks, as well as poor heat dissipation and low power utilization.

Detailed Implementation

[0021] 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. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concepts of this utility model.

[0022] See Figures 1-4 This application provides a high-efficiency single-tube heating tube structure for an electromagnetic heater for new energy vehicles, including an integrated inlet and outlet water pipe 1. The integrated inlet and outlet water pipe 1 includes a liquid supply pipe 11, a liquid drain pipe 12, and a connecting end 13. The liquid drain pipe 12 is located on the side of the liquid supply pipe 11, and the connecting end 13 is located at the end of the liquid supply pipe 11. An electromagnetic heating mechanism 2 is connected to the connecting end 13.

[0023] See Figures 1-2 Specifically, the supply pipe 11 is provided with a temperature sensor base 3, and an inlet water temperature sensor 4 is connected inside the temperature sensor base 3. The inlet water temperature sensor 4 is used to measure the inlet temperature of the coolant.

[0024] See Figures 1-2 Specifically, the drain pipe 12 is provided with a temperature sensor base 2 5, and the temperature sensor base 2 5 is connected to an outlet water temperature sensor 6, which is used to measure the outlet temperature of the coolant.

[0025] See Figures 2-3 Specifically, the electromagnetic heating mechanism 2 includes a metal tube 21, both ends of which are through openings, and one end of which is connected to the connecting end 13. A resin tube 22 is provided outside the metal tube 21, with one end open and the other end closed, and the open end is connected to the connecting end 13. A high-frequency heating coil 23 is wound around the outer wall of the resin tube 22. A drain cavity 24 is provided between the resin tube 22 and the metal tube 21, and the drain cavity 24 is connected to the drain pipe 12.

[0026] Optionally, the metal tube 31 is made of 430 high-magnetic stainless steel to increase electromagnetic induction efficiency, raise the temperature of the metal tube, and enable the coolant to undergo the first round of heat exchange with the inner wall of the metal tube.

[0027] Specifically, the metal tube 21 is provided with a baffle 25, which is designed as a vortex. The vortex-type baffle 25 can greatly increase the heating contact surface and reduce the coolant flow rate within a limited volume, thereby improving heating efficiency.

[0028] See Figure 4Specifically, a plurality of supports 7 are provided between the metal tube 21 and the resin tube 22. Each support 7 includes an inner supporting ring 71 and an outer supporting ring 72, with a supporting column 73 between the inner and outer supporting rings 71 and 72. The inner supporting ring 71 is connected to the outer wall of the metal tube 21, and the outer supporting ring 72 is connected to the inner wall of the resin tube 22. The supports 7 prevent the metal tube 21 from forming a cantilever structure, reducing its swaying inside the resin tube 22. The double-layered inner and outer supporting rings 71 and 72 are connected by the supporting column 73, forming a hollow design to ensure that coolant can flow out from it.

[0029] See Figure 1 Specifically, the integrated inlet and outlet water pipe 1 also includes an installation platform 14, which is connected to the outside of the connection end 13, and the installation platform 14 is provided with a coil interface seat 8.

[0030] The working principle of this utility model:

[0031] The coolant first enters the metal tube 21 through the supply pipe 11 of the integrated inlet / outlet water pipe 1. The coolant flows continuously within the metal tube 21 along its axial direction. Then, the coolant flows out from the port of the metal tube 21 and enters the drainage cavity 24 formed between the metal tube 21 and the resin tube 22. Subsequently, it flows in the opposite direction and exchanges heat with the outer wall of the metal tube 21. The high-temperature coolant after heat exchange flows out from the drainage pipe 12 of the integrated inlet / outlet water pipe 1. Throughout the process, the high-frequency heating coil 23 heats the metal tube 21 by applying electricity using the principle of electromagnetic induction.

[0032] The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
