When the extrusion block 726 moves upward, the sealing plate 718 The blocking plate 718 blocks the collecting chamber 719, and the coolant in the cooling box 723 enters the cooling chamber 71 through the cooling main pipe 722 and the cooling branch pipe 721. When the extrusion block 726 slides between adjacent heat sinks, the extrusion block 726, the heat sink and the partition 72 remain sealed to ensure that the coolant in the cooling chamber 71 completely enters the collecting chamber 719.

[0102] The temperature sensor is arranged outside the housing 1 to detect the temperature of the environment in which the housing 1 is located. The controller calculates the theoretical total thermal resistance of the housing 1 and the heat dissipation mechanism 2 according to formula (1). The controller calculates the theoretical maximum temperature in the sealed cavity 11 under the heating power of the transformer according to the temperature of the environment in which the housing 1 is located detected by the temperature sensor, the theoretical total thermal resistance of the housing 1 and the heat dissipation mechanism 2 calculated in step 1 and formula (2). The controller compares the calculated theoretical maximum temperature in the sealed cavity 11 under the heating power of the transformer with the preset working temperature. If the calculated theoretical maximum temperature in the sealed cavity 11 under the heating power of the transformer is greater than the preset working temperature, the controller controls the alarm to sound an alarm. The user is reminded that the heat dissipation effect of the heat dissipation mechanism 2 is not ideal under the heating power of the transformer, and the working environment temperature in the sealed cavity 11 is too high, which will affect the normal use of the transformer. A water cooling or air cooling device should be installed outside the heat dissipation mechanism 2 for heat dissipation, or the material of the heat dissipation mechanism 2 should be replaced or the number of heat dissipation plates in the heat dissipation mechanism 2 should be increased.
