Embodiment:
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
The vehicle exhaust heat exchanger that heat exchange amount is controlled, comprising: suction tude 1, outlet pipe 2, liquid inlet pipe 3, heat conduction silicone oil 11, air chamber 5, catch box 6 and heat pipe 8;
