Document Type and Number:
Japanese Patent JP7119293
Kind Code:
B2
Abstract:
To provide a heat exchanger capable of adjusting a first fluid temperature of a first fluid-side circuit without depending on electronic control such as rotational frequency control of a water pump.SOLUTION: A heat exchanger 1 causes a microcomputer for controlling a second fluid-side circuit to control the second fluid-side circuit based on a first fluid temperature at a first fluid outlet and a target outlet temperature, while a heat responsive bypass valve 27 using an elastic member 31 to adjust a flow rate of first fluid flowing in a bypass passage 15 according to a first fluid temperature at a first fluid inlet, wherein the elastic member expands/contracts depending on temperature. Consequently, the heat exchanger can change a mixing ratio of a flow rate of first fluid flowing in the bypass passage 15 and a flow rate of first fluid flowing in a main passage 11 with a water supply amount kept constant, and then adjusts a temperature of first fluid in a first fluid-side circuit.SELECTED DRAWING: Figure 1
