Detailed Description
The technical solutions of the present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Electric heaters for electric vehicles are commonly used to heat a fluid medium to provide heat to a mechanism such as a vehicle air conditioning system, and thus heat management of the fluid medium is important. The traditional temperature measurement mode is usually that a thermocouple or a thermal resistor is inserted into a measurement hole in a flow passage cavity leading to an electric heater, and a measured electric signal is transmitted to a PCBA through a wire harness to realize temperature acquisition. However, in the electric heater product, the requirement for the wiring harness is high due to high internal ambient temperature, electromagnetic interference, etc., and complicated wire clamping and wiring are required, resulting in low installation efficiency. On the other hand, a plate end connector, a cable, and the like are generally required when the wire harness is arranged, which results in a high cost of the electric heater as a whole.
For solving above-mentioned problem to a certain extent, this application provides a temperature measurement structure of electric heater that need not the cable connection. As shown in fig. 2, the temperature measuring structure includes: a housing 10, the housing 10 for defining a flow passage of an electric heater; a finished circuit board 20 (such as PCBA), the finished circuit board 20 is arranged at the outer side of the side wall of the shell 10 for limiting the flow channel, and the temperature measuring element 30 facing the shell 10 is arranged on the finished circuit board 20; the heat conducting structure 11, the heat conducting structure 11 runs through the sidewall of the housing 10, so that the first end of the heat conducting structure 11 extends into the flow channel, the second end extends to below the temperature measuring element 30, and the second end of the heat conducting structure 11 is provided with an accommodating groove 111 for accommodating the temperature measuring element; and a heat transfer medium 40, the heat transfer medium 40 being disposed in the accommodating groove 111 to transfer heat between the temperature measuring element 30 and the heat transfer structure 11.
According to the temperature measuring structure of the embodiment, when the electric heater works, the fluid medium in the flow channel flows through the first end of the heat conducting structure 11, so that the heat of the fluid medium reaches the temperature measuring element 30 through the heat transfer of the heat conducting structure 11 and the heat conducting medium 40, the temperature measuring element 30 detects the temperature of the fluid medium in the flow channel and transmits a signal to the finished product circuit board, the temperature measuring structure of the electric heater without a wiring harness is realized, the integral structure is simplified, the cost is reduced, and the reliability is higher compared with the connection of the wiring harness.
Wherein, heat-conducting medium 40 fully fills in holding tank 111 to be used for reducing the space between heat conduction structure 11 and the temperature measurement element 30, improve heat conduction efficiency, heat-conducting medium 40 is preferably colloid or paste, and then can provide certain degree of cushioning effect when taking place the vibration in order to protect temperature measurement element 30. The heat conducting structure 11 may be a heat conducting member hermetically mounted or welded to the housing 10, and the material of the heat conducting structure 11 may be the same as or different from that of the housing 10. Preferably, as shown in fig. 2, the heat conducting structure 11 is formed integrally with the housing 10, thereby providing more reliable structural stability.

As shown in fig. 3, too close a distance between the fixing point P of the finished circuit board 20 and the housing 10 and the heat conducting structure 11 may cause the fixing point P to be affected by heat, and too far a distance may not ensure the stability of the position of the temperature measuring element 30. The above-mentioned distance is preferably limited to be 5-20mm in the application, so that under the condition of ensuring stability, the heat conducting structure 11 is spaced from the fixing position of the finished circuit board 20 and the shell 10, the influence of the heat conducting structure 11 on the fixed installation of the finished circuit board 20 is reduced, and the fixing position P is prevented from being heated and loosened.

This clearance is used for avoiding finished product circuit board 20 and heat conduction structure 11 to contact, and then reduces the heat of transmission on heat conduction structure 11 or the influence that finished product circuit board 20 self generates heat to finished product circuit board 20. The dimensions of the above-mentioned opening portion 22 (a and B as shown in fig. 3) are preferably larger than the dimensions of the second end of the heat conducting structure 11 so that the finished wiring board 20 located outside the opening portion 22 does not directly contact the heat conducting structure 11.

The second end of the thermal conducting structure 11 of the temperature measuring structure is located in the flow channel of the electric heater and is arranged away from the heating element of the electric heater, thereby preventing the measuring process of the temperature measuring element 30 from being affected by the heat of the heating element. The flow channel of the electric heater generally comprises a water inlet, a water outlet, an inlet main flow channel extending from the water inlet and an outlet main flow channel extending from the water inlet, and preferably, the inlet main flow channel and the outlet main flow channel are respectively provided with at least one temperature measuring structure, so that the temperature of the fluid medium entering and flowing out of the flow channel can be accurately measured, and the working state of the electric heater can be accurately controlled.
