Description

Technical Field

[0001] This utility model relates to the field of heating device technology, and in particular to a split structure for a pipe heater used for heating. Background Technology

[0002] With the rapid development of new energy vehicles, traditional automakers are joining the industry, intensifying market competition and raising the bar for vehicle quality and component production capacity. Since the optimal operating temperature for batteries is between 25-35℃, battery thermal management systems are widely used to cope with the effects of extreme weather conditions, reduce battery damage, and extend battery life. Meanwhile, energy storage heaters also play a crucial role due to the imbalance between power generation and consumption in different regions and the varying electricity demands at different times of the year. However, existing water heaters on the market have some drawbacks. For example, the aluminum profiles in pipe heaters integrate several PTC chambers into one unit. Therefore, if the PTC is damaged during production, the entire heater will be scrapped. The six sides of the integrated pipe heater are symmetrically arranged in pairs to form a hexagon. Therefore, the PTC sheet inside the chamber needs to be squeezed and fixed from top to bottom during production. It is relatively difficult to make the two symmetrical sides evenly and evenly press, which is not conducive to mass production. Since pipe PTC heaters have very high requirements for the cleanliness and smoothness of the inner cavity of the profile, the old-style profiles are large and heavy, and the chambers are often damaged during processing. Damage to one chamber will cause the entire profile to be scrapped. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a split structure for a pipeline heater that is simple to assemble, easy to disassemble, and has low maintenance costs.

[0004] To solve the above-mentioned technical problems, the split structure of the pipe heater of this utility model includes a pipe body and multiple grooves uniformly distributed along the axial direction directly machined on the pipe body. It also includes multiple PTC heating tubes for placement in each of the grooves. Each PTC heating tube is composed of an aluminum tube and a PTC heating core inserted into the aluminum tube. The PTC heating core is inserted into the aluminum tube and squeezed and fixed as an independent heating component. Each heating component is installed in a corresponding groove to form the entire pipe heating structure.

[0005] The tube has a hexagonal cross-section and is made of aluminum.

[0006] The number of grooves is six.

[0007] The PTC heating element is attached to the groove with adhesive.

[0008] A protrusion with an inverted trapezoidal cross-sectional shape is formed between adjacent grooves.

[0009] Advantages of this utility model:

[0010] (1) Since the PTC heating tube, which serves as the carrier, is a separate unit, when extruding the tube body in the pipeline heater manufacturing process, it is only necessary to lay the PTC heating tube flat. Unlike the old-fashioned pipeline heater, it does not require consideration of two symmetrical PTC heating tubes. Furthermore, our company has already achieved automated assembly of the PTC heating core in its production process, which has greatly improved production efficiency and pass rate.

[0011] (2) Simply attach the assembled and inspected PTC heating tube to the groove of the tube body with adhesive and align the two sides to complete the assembly.

[0012] (3) Compared with the old-fashioned pipe heater, which has extremely high requirements for the cleanliness and flatness of the profile groove and is easily damaged during processing, this utility model only needs to ensure the matching degree between the groove and the heating aluminum tube, without the need to perform high-precision processing on the groove of the entire profile, thereby avoiding the problem of groove damage caused by the large size and heavy weight of the profile.

[0013] (4) When it is found that some aluminum tube cavities are not qualified during production, only the individual aluminum tubes need to be scrapped. Unlike the old-fashioned pipe heaters, the entire profile does not need to be scrapped, which greatly saves the later maintenance costs.

[0014] (5) The spaced protrusions act like heat sinks, increasing the heat dissipation area of ​​the tube. The groove design makes the entire pipe heater structure more compact and increases its aesthetic appeal. Attached Figure Description

[0017] The split structure of the pipe heater of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1 As shown, the split structure of the pipeline heater includes a pipe body 1 and multiple axially evenly distributed grooves 3 machined directly on the pipe body 1. It also includes multiple PTC heating tubes 4 for placement within each groove 3. Each PTC heating tube 4 consists of an aluminum tube 2 and a PTC heating core 5 inserted into the aluminum tube 2. The PTC heating core 5 is inserted into the aluminum tube 2 and pressed and fixed as an independent heating component. Each heating component is installed in a corresponding groove 3 to form the entire pipeline heating structure. Each groove 3 contains a detachable PTC heating tube 4, such as... Figure 2As shown, the PTC heating tube 4 is glued to the groove 3 with adhesive. Assembly is completed simply by gluing the assembled and qualified PTC heating tube into the groove of the profile with adhesive and aligning the two sides. Specifically, the tube body 1 has a hexagonal cross-section and is made of aluminum profile. There are six grooves 3, which are evenly distributed around the circumference of the tube body 1. The tube body 1 has a central hole 7 for fluid inflow at the center. The surface of the central hole 7 is smooth. Between adjacent grooves 3, there are protrusions 6 with an inverted trapezoidal cross-section. The bottom surface of the trapezoid is arc-shaped, which increases the heat dissipation area and also enhances the aesthetics.

[0019] The PTC heating element 4 consists of an outer aluminum tube 2 and a PTC heating core 5 inserted into the aluminum tube 2. Since the aluminum tube 2, which serves as the carrier, is a separate unit, during the extrusion process of manufacturing the PTC heating element 4, it is only necessary to lay this aluminum tube 2 flat. Unlike the old-fashioned pipe heaters, which require consideration of two symmetrical PTC heating elements 4, the PTC heating core 5 has been automated in our company's production, resulting in a significant improvement in production efficiency and pass rate. Because the aluminum tubes are all separate units, if an individual aluminum tube cavity is found to be defective during production, only that single aluminum tube needs to be scrapped, instead of scrapping the entire profile as in the old-fashioned pipe heaters, thus achieving cost savings.
