Abstract

A detection apparatus and a server are provided, where the apparatus is configured to detect whether a coolant heat pipe or a solenoid valve on the coolant heat pipe in a device is abnormal, and the apparatus includes a control chip. The control chip can control a working state of the solenoid valve. The control chip can further obtain a temperature of a component in the device. When it is detected whether the coolant heat pipe or the solenoid valve is abnormal, the control chip may obtain a temperature difference of the component in the device when the working state of the solenoid valve is controlled, and relatively conveniently determine whether the coolant heat pipe or the solenoid valve is abnormal based on the temperature difference.

Dependent claims

A detection apparatus, wherein the apparatus is configured to detect whether a coolant heat pipe in a device or a solenoid valve on the coolant heat pipe is abnormal, and the apparatus comprises a control chip;

and
the control chip is configured to:
control the solenoid valve to change from an open state to a closed state, and obtain a first temperature difference of the component in the device after a temperature of the component in the device is stable in the closed state;
and
control the solenoid valve to change from the closed state to the open state, and obtain a second temperature difference of the component in the device after the temperature of the component in the device is stable in the open state;
determine that the coolant heat pipe is abnormal and that the solenoid valve is normal based on the second temperature difference being detected as being lower than a second threshold value and the first temperature difference being detected as being greater than a first threshold value;
and
determine that the solenoid valve is abnormal based on the second temperature difference being detected as being lower than the second threshold value and the first temperature difference being detected as being lower than the first threshold value.
