熱管理装置
Document Type and Number:
Japanese Patent JP6451535
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress fluctuation in pressure of a heat medium without enlarging the capacity of a reserve tank.SOLUTION: This heat management apparatus is provided with: pumps 11, 12 that suck and discharge heat media; circulation flow passages 41-49, 53 through which the heat media circulate; bypass flow passages 50, 51 through which the heat media flow bypassing parts of the circulation flow passages; pressure adjustment means 57 which is connected to the bypass flow passages 50, 51 and adjusts the pressure of the heat media to a reference pressure; and pressure loss ratio adjustment means 21, 23 that adjust a pressure loss ratio calculated by dividing pressure losses of upstream side flow passages 50a, 51a of the bypass flow passages 50, 51 located on the heat-medium upstream side of the pressure adjustment means 57 with pressure losses of downstream side flow passages 50b, 51b of the bypass flow passages 50, 51 located on the heat-medium downstream side of the pressure adjustment means 57. The pressure loss adjustment means sets, when the temperature or the pressure of the heat media is high, a pressure loss ratio smaller than that when the temperature or the pressure of the heat media is low.SELECTED DRAWING: Figure 4
