Title:
TEMPERATURE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/163055
Kind Code:
A1
Abstract:
Provided is a temperature control device which cuts costs overall by reducing the number of types of temperature sensors. One aspect of this temperature control device (1) comprises: a motor (2) which drives a vehicle (80); an oil circuit (90) through which oil flows; a cooling water circuit (10) through which cooling water flows; an oil cooler (5) which performs heat exchange between the oil and the cooling water; a first temperature measurement unit (8) which measures the temperature of the cooling water flowing into the oil cooler; a second temperature measurement unit (9) which measures the temperature of the cooling water flowing out from the oil cooler; and a calculation unit (61) which connects to the first temperature measurement unit and the second temperature measurement unit. The calculation unit calculates the temperature of the oil flowing into the oil cooler on the basis of a difference between the temperature of the cooling water measured by the first temperature measurement unit and the temperature of the cooling water measured by the second temperature measurement unit.
