Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric heater technology, and in particular to a heater with temperature control. Background Technology
[0002] PTC heating elements, also known as PTC heaters, consist of PTC ceramic heating elements and aluminum tubes. This type of PTC heating element has the advantages of low thermal resistance and high heat exchange efficiency. It is an automatic temperature-controlled, energy-saving electric heater. Under any application conditions, it will not produce the surface "reddening" phenomenon of electric heating tube heaters, thus avoiding safety hazards such as burns and fires.
[0003] In actual use, the temperature controller needs to be connected to the heater to control temperature changes through the temperature controller's sensing. However, the external temperature controller can only be connected to one side of the heater, resulting in inconsistent temperature sensing and poor sensitivity, which makes it inconvenient to use. Utility Model Content
[0004] Based on the existing problems of inconsistent temperature sensing and poor sensitivity in heaters that rely on external temperature controllers for temperature control, this invention proposes a heater with integrated temperature control.
[0005] This utility model discloses a temperature-controlled heater, including a heating element, with heat-conducting boxes on both sides of the heating element. Each heat-conducting box contains a metal heat sink. The surfaces of multiple heat-conducting boxes are respectively provided with a fixed connecting seat and a wiring seat. A disposable fuse and a resettable temperature protector are fixedly connected to the surfaces of the multiple heat-conducting boxes. The fixed connecting seat has a fixed connecting wire on its surface, the wiring seat has a wiring connecting wire on its surface, the disposable fuse has a fuse connecting wire on its surface, and the resettable temperature protector has a protector connecting wire on its surface.
[0006] Preferably, the surface of the heating element is fixedly connected to the surface of the heat-conducting box, and the plurality of heating elements are arranged in a linear array along the axial direction of the heat-conducting box.
[0007] Preferably, the surface of the metal heat sink is fixedly connected to the inner wall of the heat conduction box, and the metal heat sink is corrugated.
[0008] Preferably, both sides of the disposable fuse and both sides of the resettable temperature protector are fixedly connected to the surfaces of the two heat-conducting boxes.
[0009] Preferably, the surface of the resettable temperature protector is fixedly connected to the surface of the disposable fuse and the surface of the wiring harness via two protector connection wires.
[0010] Preferably, the plurality of fixed connecting seats and the plurality of wire inserts are linearly arrayed along the axial direction of the heat conduction box, and the surfaces of two wire inserts are fixedly connected by the wire insert connecting line.
[0011] The beneficial effects of this utility model are as follows:
[0012] By installing a one-time fuse and a resettable temperature protector on the surface of the heat transfer box, the product temperature becomes more consistent and can sense and control temperature changes on its own. This solves the technical problems of inconsistent temperature sensing and poor sensitivity in existing heaters that rely on external temperature controllers for temperature control.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] Reference Figures 1-3 A temperature-controlled heater includes a heating element 1, with heat-conducting boxes 2 on both sides of the heating element 1. Metal heat sinks 3 are installed inside the heat-conducting boxes 2. Fixed connecting seats 4 and wire-inserting seats 5 are respectively installed on the surfaces of multiple heat-conducting boxes 2. A disposable fuse 6 and a resettable temperature protector 7 are respectively fixedly connected to the surfaces of multiple heat-conducting boxes 2. Fixed connecting wires 8 are installed on the surface of the fixed connecting seat 4, wire-inserting connecting wires 9 are installed on the surface of the wire-inserting seat 5, fuse connecting wires 10 are installed on the surface of the disposable fuse 6, and protector connecting wires 11 are installed on the surface of the resettable temperature protector 7.
[0019] The surface of the heating element 1 is fixedly connected to the surface of the heat conduction box 2, and multiple heating elements 1 are arranged in a linear array along the axial direction of the heat conduction box 2.
[0020] Furthermore, heat conduction boxes 2 are provided on both sides of the multiple heating elements 1 to evenly dissipate the heat from the heating elements 1, making the product temperature more consistent.
[0021] The surface of the metal heat sink 3 is fixedly connected to the inner wall of the heat conduction box 2, and the metal heat sink 3 is corrugated.
[0022] Furthermore, the corrugated metal heat sink 3 increases the area of the heat sink, allowing heat to dissipate more quickly and achieving the same heat dissipation effect in a smaller space.
[0023] Both sides of the disposable fuse 6 and both sides of the resettable temperature protector 7 are fixedly connected to the surfaces of the two heat-conducting boxes 2.
[0024] Furthermore, the heater can sense and control temperature changes on its own through the surface of the heat conduction box 2, making the sensing more sensitive and efficient.
[0025] The surface of the resettable temperature protector 7 is fixedly connected to the surface of the disposable fuse 6 and the surface of the wire insert 5 via two protector connection wires 11.
[0026] Furthermore, the resettable temperature protector 7 limits the temperature of the heater through a one-time fuse 6 to prevent overheating from causing burns, fires, or other safety hazards.
[0027] Multiple fixed connectors 4 and multiple wire inserts 5 are linearly arrayed along the axial direction of the heat conduction box 2, and the surfaces of two wire inserts 5 are fixedly connected by wire insert connecting lines 9.
[0028] Furthermore, the fixed connection seat 4 is connected to the power supply via the fixed connection line 8, and the internal components of the heater are connected via the fixed connection seats 4 and the wire inserts 5 respectively provided on the surface of the multiple heat conduction boxes 2.
[0029] By setting a one-time fuse 6 and a resettable temperature protector 7 on the surface of the heat conduction box 2, the product temperature is made more consistent and can sense and control temperature changes on its own. This solves the technical problem of inconsistent temperature sensing and poor sensitivity in existing heaters that rely on external temperature controllers for temperature control.
