The first temperature threshold, the first temperature threshold and the third temperature threshold can be set by staff according to actual conditions, the first temperature threshold can be set according to performance parameters of vegetable oil, for example, after the first temperature value reaches the first temperature threshold, the viscosity of the vegetable oil is reduced to be suitable for operation of a transmission pump, the second temperature threshold indicates that the heating value of the transformer device is enough to maintain the viscosity of the vegetable oil to be suitable for operation of the transmission pump, heat preservation is not needed at the moment, an air outlet is opened to promote heat dissipation, the transformer device stably operates, the third temperature threshold indicates that the transformer device operates to generate a large amount of heat, the air in a cooling cavity is simply opened by the air outlet, natural heat exchange between the air and the outside air is insufficient to dissipate the heat, and at the moment, the fan can be controlled to start and accelerate air flow, so that the heat dissipation is accelerated.
The control method of the invention detects the first temperature value, the second temperature value and the third temperature value, and utilizes the comparison of the first temperature value, the second temperature value and the third temperature value with the first temperature threshold value, the second temperature threshold value and the third temperature threshold value as judging conditions for operation at different stages, when the temperature is too low and vegetable oil is solidified, the first heating component and the second heating component are firstly utilized to start operation, the vegetable oil in the heat dissipation oil cavity and the first pipe body or the second pipe body is heated, so that the viscosity of the vegetable oil is reduced, at the moment, the operation of the transmission pump is controlled, the circuit breaker can be closed, the transformer device is started to operate, thereby preventing the transmission pump from being damaged due to forced driving of the transmission pump, then the transformer device operates, the circularly flowing vegetable oil can take away heat emitted from the transformer device, and the temperature of the vegetable oil is gradually increased along with the operation of the transformer device, at the moment, the heating of the first heating component and the second heating component can be stopped, the air outlet is opened by the control piece to dissipate heat, and when the temperature of the vegetable oil is further increased, the fan can be controlled to further raise the temperature of the vegetable oil, so that the heat dissipation device is forced to operate stably.
In some embodiments of the present invention, as shown in fig. 4, the control method further includes:
s910, when the first temperature value is higher than the first temperature threshold value and the second temperature value is lower than the second temperature threshold value, the control module outputs first power to drive the transmission pump to operate;
s920, when the second temperature value is higher than the second temperature threshold value, the control module outputs second power to drive the transmission pump to operate; wherein the second power is greater than the first power.
When the first temperature value is higher than the first temperature threshold value and the second temperature value is lower than the second temperature threshold value, the viscosity of the vegetable oil is only required to be lower at the moment, and the vegetable oil is still relatively viscous, so that the vegetable oil drives the transmission pump to operate at lower first power, the transmission pump cannot burn out due to high load, the viscosity of the vegetable oil can be reduced along with slow flow of the vegetable oil, and the vegetable oil is required to be cooled when the second temperature value is higher than the second temperature threshold value, and the viscosity of the vegetable oil is required to be lower at the moment, and the fast flow of the vegetable oil is required to take away heat dissipated by the transformer device, so that the transmission pump can be driven to operate at higher second power.
