Description
Technical Field
The present invention relates to a seal structure, and more particularly, to an integrated module and an in-module seal technology for use in designing a lightweight, high-efficiency thermal management system that can be implemented in a vehicle.
Background
Various driving motors generate a lot of heat during operation, and especially the heat generation rate of motors with small volume and high output power (such as a new energy automobile driving motor) is high. The motor is too high in temperature and can damage the insulating layers of the motor winding coils, so that the motor winding coils fail. Moreover, the motor may operate under a wide range of ambient temperature, humidity, dust, dirt conditions, so the architecture of the motor cooling system must operate effectively with large variations in the surrounding operating environment. Therefore, the motor needs to cool the stator/rotor and the outer shell, maintain a reasonable temperature range, ensure the stability of the running environment of the motor and ensure the running and output stability of the motor.
In addition, the high-efficiency stable operation of various high-power electronic devices and battery packs of the current new energy automobile requires a stable environment temperature (not high and low), and the heat contained in the vehicle needs to be monitored and managed in the whole process when the vehicle operates. If the heat is not reasonably utilized in autumn and winter, the energy utilization rate of the automobile is reduced (especially a new energy automobile), and the one-time charging driving mileage is shortened. In the technical field of heat management of new energy automobiles, in order to improve the utilization rate of the internal space of the automobile, reduce the number of parts, reduce weight and reduce consumption, the trend of integrating the whole automobile heat management cooling flow channel and the flow channel control assembly gradually exists. The change can reduce the total length of the flow channel and the abrupt change of the flow channel, reduce the energy consumption of the flow channel power source and the energy dissipation in the flow channel, and improve the effective utilization rate of the energy.
The integrated module generally comprises a runner switching module, and the runner switching module comprises a fixed runner, a switching valve core, a sealing member, a driver, a valve core pressing plate and other components, wherein the sealing member can be an independent sealing member or an assembly sealing member, and the overall performance of the integrated module is related to the sealing member, so that a sealing member structure with convenient installation and reliable sealing is needed.
