[0038] The waste heat collecting apparatus 100 according to the first embodiment of the present invention is applied to a vehicle having an engine 10 for generating driving force for the vehicle. The waste heat collection device 100 is provided in the exhaust pipe 11 and the waste heat collection circuit 30 of the engine 10 . Refer below Figure 1-5 to describe the structure in more detail. figure 1 is a schematic diagram showing the waste heat collection device 100 installed in a vehicle. FIG. 2 is a cross-sectional view of the waste heat collection device 100 . image 3 It is a cross-sectional view along line III-III in FIG. 2 . Figure 4 is a cross-sectional view showing the valve device 150 provided in the waste heat collecting apparatus 100 in a valve open state. Figure 5 is a sectional view showing the valve device 150 in the valve closed state.
[0039] like figure 1 As shown, the engine 10 is a water-cooled internal combustion engine, and has an exhaust pipe 11 ...

[0085] Figure 9 A second embodiment of the invention is shown. The valve device 150 of the second embodiment differs from the valve device of the first embodiment in that a microhole 152e is provided at a gate portion 152c. According to this variation, even when the hole 152d is completely closed by the valve body 155 , a small flow of condensed water may flow back from the condensing part 130 to the evaporating part 110 . In the case where the engine 10 is running at a high load but the radiator 21 has additional coverage (for example, additional capacity) for the cooling operation, circulation of the working fluid is performed through the micro holes 152e, performing waste heat collection operation. The size of the microhole 152e is determined according to the additional coverage of the heat sink 21 so that overheating can be avoided even when a certain amount of working fluid is circulated through the microhole 152e.
[0086]As described above, even when the hole 152d is...

[0088] Figure 10 A third embodiment of the present invention is shown. The diaphragm type valve device 150 of the first embodiment is replaced by a thermo-wax type (thermo-wax) valve device 170, wherein the valve device 170 opens and closes the passage according to the temperature of the engine coolant.
[0089] Specifically, the valve device 170 is composed of a wax portion 171 , a connecting rod 172 and bellows 173 . Wax is filled into the hot wax portion 171, and the wax expands or contracts according to the temperature of the coolant. One end (upper end) of the elongated connecting rod 172 is inserted into the hot wax portion 171, and the other end extends downward. Such as Figure 10 As shown, the connecting rod 172 moves downward or upward according to the expansion or contraction of the wax. That is, the connecting rod 172 slides downward due to the expansion of the wax, and the connecting rod 172 slides upward due to the contraction of the wax. The wax portion 17...
