[0021] This invention designs an auxiliary structure connecting a heating element and a temperature sensing element to improve heat conduction speed and shorten the response time of a thermostat. The auxiliary structure is integrally molded from a high thermal conductivity material and consists of a base 1 and an auxiliary plate 2. The upper contact surface 9 of the auxiliary plate 2 is tightly fitted to the heating element. The bottom of the auxiliary plate 2 is provided with an arc-shaped contact surface 8, which is connected to the base 1, thus significantly increasing the heat transfer area. The cavity 7 at the bottom of the base 1 is tightly fitted to the temperature sensing element of the thermostat. The arc-shaped contact surface 8 is partially or completely embedded in the base 1, which shortens the distance between the heating element and the temperature sensing element and improves the efficiency of heat conduction.
[0022] The high thermal conductivity material is selected from one of alumina, aluminum nitride, silicon nitride, zirconium oxide, silicon carbide, cordierite, or mullite ceramics. The above materials have high thermal conductivity and low heat capacity.
[0023] As an explanation of the shape of chamber 7, the shape of chamber 7 is circular, rectangular, elliptical or regular polygonal, with circular being the most common choice; the top end face of chamber 7 is flat, curved or spherical.
[0024] The auxiliary disk 2 has a vertical surface 3 on both sides, and the two vertical surfaces 3 are arranged in parallel. A rounded transition surface 4 is provided between the vertical surface 3 and the upper surface of the auxiliary disk 2. The rounded transition surface 4 can effectively reduce the impact damage to the auxiliary disk 2.
[0025] A thermally conductive silicone or thermally conductive pad is provided between the auxiliary disk 2 and the heating element; a thermally conductive silicone or thermally conductive pad is provided between the chamber 7 and the temperature sensing element. The use of thermally conductive silicone or thermally conductive pads improves the tight contact between the heating element (or temperature sensing element) and the auxiliary structure.
[0026] The upper end of the base 1 is provided with reinforcing ribs 5 on both sides of the auxiliary disk 2. The reinforcing ribs 5 strengthen the structure of the auxiliary disk 2 and the base 1, greatly improving the structural strength and stability.

[0027] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.
[0028] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0029] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
