[0019] The utility model will be further described in connection with the drawings:

[0020] Referring to the drawings: this new energy automobile heater, including shell 1, and the shell cover 2 that covers on shell 1, be provided with the circuit box 21 with external circuit interface on shell cover 2, the lower short shaft side of shell 1 is provided with two external pipe connections 3 respectively as water inlet end, water outlet end uses, the inner cavity is provided with the heat conducting piece 4 that allows water liquid to flow in, and the heat conducting piece 4 includes the outer mounting seat 41 that is integrally formed and is all made of metal material, and the liquid pipeline 42 that flows in, the upper end, the lower end of outer mounting seat 41 are provided with the assembly end point 6 for limiting the final assembly position of thick film heater 5 on heat conducting piece 4, the liquid pipeline 42 that flows in is in multilayer spiral configuration and both ends are connected with corresponding external pipe connections 3, and thick film heater 5 is electrically connected with circuit box 21. The principle of the utility model lies in, shell 1 provides installation space, so that external pipe connections 3, heat conducting piece 4 and thick film heater 5 can be placed in, shell cover 2 plays the role of dustproof protection, and sealing ring is arranged between shell 1 and shell cover 2 to achieve the effect of preventing leakage, heat conducting piece 4 is integrally formed by pouring on the mold, which simplifies the molding difficulty, and the metal material itself can realize better heat conduction after thick film heater 5 is heated, also has heat preservation effect, so that the heating time of thick film heater 5 is shortened, the liquid pipeline 42 that flows in is in multilayer spiral configuration, which can prolong the running track of the liquid, increase the liquid volume of the heated liquid, and also does not need liquid extrusion, on the other hand, the pressure bearing property of the liquid pipeline 42 that flows in is increased (that is, deformation does not occur), which can prolong the service life of the heat conducting piece 4, and also reduce the power consumption level of the heater. In the embodiment, the liquid pipeline 42 that flows in is in double-layer spiral configuration.

[0021] The outer peripheral surface of the outer mounting base 41 has two outwardly extending inner liquid channel outer wrapping feet 411. The inner liquid channel 42 is not only a single spiral configuration, but specifically two linear portions and a spiral portion. The two linear portions are used to achieve plug-in cooperation with other components, and in this embodiment, plug-in cooperation with the external channel connecting piece 3, so that quick and convenient assembly can be achieved. The inner liquid channel outer wrapping feet 411 reduce the length of the linear portion exposed to the outside by wrapping the linear portion, achieving two effects: effect one, which can increase the structural strength of the plug-in cooperation portion with the external channel connecting piece 3; and effect two, which can increase the heat preservation effect, thereby ensuring the heat conduction of the heat conducting piece 4 and avoiding heat loss.

[0022] The lower short axis side of the outer shell 1 is provided with protrusions 11 matching the position and number of the external channel connecting pieces 3. The protrusions 11 have inner cavities and communicate with the inner cavities of the outer shell 1. The external channel connecting pieces 3 are placed in the inner cavities of the protrusions 11 and connected thereto. After connection, one end of the external channel connecting piece 3 protrudes out of the protrusion 11, and the other end abuts against the corresponding inner liquid channel outer wrapping foot 411. This arrangement takes into account that the outer mounting base 41 has the inner liquid channel outer wrapping feet 411, which extend to the lower short axis side of the outer shell 1 and thus occupy the required length position of the external channel connecting piece 3. Therefore, the length of the area of the outer shell 1 corresponding to the protrusions 11 is increased by using the protrusions 11, so that the extension required by the inner liquid channel outer wrapping feet 411 is satisfied, and at the same time, the required length distance of the external channel connecting piece 3 is also satisfied. Moreover, the inner liquid channel outer wrapping feet 411 and the external channel connecting piece 3 can abut against each other, which means that the linear portion of the inner liquid channel 42 (the portion exposed outside the inner liquid channel outer wrapping foot 411) is completely inserted into the external channel connecting piece 3, reducing the stress on the linear portion of the inner liquid channel 42, and a sealing ring can also be arranged at the abutting section between the external channel connecting piece 3 and the inner liquid channel outer wrapping foot 411. In this embodiment, the external channel connecting piece 3 and the protrusion 11 are connected in a threaded connection manner.

[0023] The external channel connecting piece 3 is a connecting pipe. One of the connecting pipes is provided with a temperature control sensor 9, and the other is provided with a flow switch 8. One of the inner liquid channel outer wrapping feet 411 is provided with a manual temperature control switch 7, and the other is provided with an automatic temperature control switch 10. The connecting pipes are convenient to connect with external pipes. The temperature control sensor 9 is used to monitor the temperature reflected by the heat conducting piece 4 when it is heated. When the temperature exceeds the preset value, the automatic temperature control switch 10 can automatically cut off the power supply to prevent the equipment from overheating and being damaged. The manual temperature control switch 7 can be manually turned off by the user after the automatic temperature control switch 10 fails, achieving double protection. The flow switch 8 stops the heating of the thick film heater 5 when the flow reaches or is lower than the preset value, preventing empty heating and providing good protection measures, thereby prolonging the service life of the equipment and improving the reliability.

[0024] The outer mounting seat 41 is made of aluminum material, and the inner liquid pipeline 42 is made of copper material, the aluminum material and the copper material have good heat conductivity, and the heat conductivity of the copper material is better than that of the aluminum material, so that the setting can save production cost and ensure the heat conductivity, because the inner liquid pipeline 42 is directly contacted with water, the copper material can quickly conduct heat and realize rapid heat exchange with water.

[0025] The assembly end 6 includes an inner wall 61 formed on the outer mounting seat 41, and a placing space 62 defined in the inner wall 61 and allowing the thick film heater 5 to be placed in, the inner wall 61 is further formed with a bayonet 611 on the outer mounting seat 41, the bayonet 611 is arranged in the wiring end of the thick film heater 5, and the thick film heater 5 can abut against the inner wall 61 after being placed in the placing space 62, the abutment can generate a certain friction degree, that is, the thick film heater 5 is prevented from being deflected when being completely limited in the outer mounting seat 41 by the bolt, and a certain positioning effect is achieved, and the bayonet 611 can also adapt to the setting of the wiring end of the thick film heater 5, that is, the wiring end will not be raised due to the existence of the edge blocking strip, and the thick film heater 5 is ensured to be placed flat. In the embodiment, the thick film heater 5 is connected with the outer mounting seat 41 by a screw as a connecting piece after being placed in the assembly end 6.

[0026] The inner wall 61 is in a circular configuration, the shape of the thick film heater 5 is matched with the shape of the inner wall 61, so that the shape of the thick film heater 5 is also circular, and the circular structure can uniformly disperse external force to the entire circumference when force is applied (such as extrusion), and the stress concentration phenomenon (local stress is much higher than the average value) is significantly reduced, and the durability is better than that of a rectangular shape which is prone to stress concentration at the corners.

[0027] The bottom surface of the shell 1 is provided with a ring seat 12, the outer mounting seat 41 is arranged on the ring seat 12 and forms a spacing distance with the bottom surface of the shell 1 and the bottom surface of the shell cover 2, so that the local overheating of the heater is prevented, because the heating element generates a large amount of heat when working, if directly contacted with the table surface, the local temperature may be too high, and the equipment may be damaged or safety problems may be caused, the spacing distance can increase heat dispersion and reduce heat concentration in an area, so that local overheating is avoided, and better heat conduction and heat dissipation effects are provided, and stable operation of the equipment is ensured.

[0028] Although the utility model has been illustrated and described by referring to the preferred embodiments, it should be understood by those skilled in the art that various changes in form and details can be made within the scope of the claims.
