In-vehicle device temperature adjusting device and vehicle air conditioning device provided with same

An in-vehicle device temperature adjusting device which serves as a temperature adjusting device to adjust the temperature of an in-vehicle device, comprising:

• a refrigerant circuit having a compressor which compresses a refrigerant, a heat-radiating heat exchanger for letting the refrigerant radiate heat, and a heat-absorbing heat exchanger for letting the refrigerant absorb heat to cool the in-vehicle device;
• and
• a control device,
• wherein the control device stops the compressor based on the blockage of the refrigerant circuit,
• wherein the in-vehicle device includes a heat medium circulating device which circulates a heat medium,
• wherein the heat-absorbing heat exchanger cools the heat medium with the refrigerant and cools the in-vehicle device through the heat medium, and
• wherein when a state in which the number of revolutions of the compressor is higher than a predetermined number of revolutions, and the degree of decrease in the temperature of the heat medium after heat exchange with the refrigerant is smaller than a predetermined value continues for a predetermined time, the control device determines that the refrigerant circuit is blocked.
