Embodiment 1
[0115] Embodiments of the present application provide a set of heating control methods and devices, and a first motor and heat exchange system applying the heating control method. Wherein, the adjacent area of the first motor may be provided with passages for allowing liquid to pass through.
[0116]For example, the first motor may be an oil pump motor, an oil-cooled motor, etc., and the liquid used in conjunction with the first motor may be oil.
[0117] As an example, the oil pump motor may be an electric pump or a motor used to drive fluid flow in an oil pump. The oil pump may be provided with a pump oil chamber for accommodating the oil to be driven, and the oil pump motor may drive the oil in the pump oil chamber through transmission connectors such as fan blades.
[0118] As an example, the oil-cooled motor may be a motor that uses cooling oil to cool down the temperature of the motor. A passage allowing oil to pass through may be provided inside the oil-cooled motor...
Embodiment 2
[0255] The embodiment of the present application also provides an optional implementation of heating conditions.
[0256] In a third optional implementation manner of the heating control method, when the first motor is in the starting state, the heating condition in any of the heating control methods in the foregoing embodiments may also be a low-loss working condition. The control device can inject heating current into the first motor when the low-loss working condition is satisfied. Wherein, the heating current may be any implementation manner in the foregoing embodiments.
[0257] Table 10 is an example of low loss operating conditions.
[0258] Table 10
[0259]
[0260] In the embodiment of the present application, the operating conditions of the first electric motor may include two operating parameters of a rotational speed and a torque. The low-loss operating condition may be a combination of a set of rotational speed and torque corresponding to a loss heating pow...
Embodiment 3
[0282] The embodiment of the present application also provides a heating control method. This method can be applied to the heat exchange system in the foregoing embodiments. The execution subject of the embodiment of the present application may be a control device, and the control device may be located in the heat exchange system in the foregoing embodiments.
[0283] Figure 11 Schematic flow chart of the heating control method provided in the embodiment of this application Figure three . Such as Figure 11 As shown, the steps of the embodiment of the present application may include:
[0284] S301. Obtain an instruction to start the heat collecting device, and execute S302-1 and S303-1.
[0285] Wherein, as an optional implementation manner, obtaining the start-up instruction of the heat collecting device may also adopt obtaining the start-up instruction of the second electric motor as an alternative implementation manner.
[0286] S302-1. When the first motor is in a ...
