The present invention relates to an apparatus to measure heat quantity generated in testing components under various environmental conditions in order to test a performance and durability of the component using coolant such as a battery for electric vehicle, a radiator, etc. The present invention is able to increase a reliability of a test to test the performance and durability of components under various environmental conditions by performing the test by adding an accurate pressure required repeatedly in a predetermined pattern cycle to circulating coolant; equalizing the temperature of the coolant; and preventing air from flowing into the coolant. The coolant heat quantity measuring apparatus of the present invention comprises: a pressurization container (81) installed in an upper part of a coolant container (80), has smaller volume and area per square meter than the coolant container (80), and is formed to supply compressed air; a heater (82) installed in one side in the coolant container (80); a coolant return pipe (83) installed in an edge where the heater (82) is installed in the upper part of the coolant container (80); a coolant supply pipe (84) installed in an opposite edge of the coolant return pipe (83) on a lower part of the coolant container (80); and a coolant guide plate (85) which guides coolant, flowing from the coolant return pipe (83) of the upper part to the coolant container (80), to pass the heater (82) and flow in the coolant supply pipe (84) of the lower part. |
