Description
Technical field
The present invention relates to a kind of waste heat recovery plant that is used for automobile or other vehicle.
Background technique
In recent years, technique known was to utilize the heat conductive tube principle to reclaim the used heat of waste gas and this used heat is used to help warming-up etc. from the vent systems of vehicle motor.
This waste heat recovery plant has been arranged the vaporizer of heat conductive tube in waste pipe, in the cooling water passage of motor, arranged the condenser of heat conductive tube, and use the waste heat cooling water (for example, referring to Japanese Patent Laid-Open Publication (A) 62-268722 number) of waste gas.
In addition, as the heat exchanger that utilizes the heat conductive tube principle, ring-like heat conduction tubular heat exchanger (for example, referring to Japanese Patent Laid-Open Publication (A) 4-45393 number) has been proposed.This patent has the sealing circulation canal that forms loop, be sealed in evaporating and condensable heat transfer fluid, be arranged in the circulation canal and by vaporizer and condenser from the heat of vaporization working fluid of outside input in the circulation canal, described condenser is arranged in the position of the vaporizer that is higher than circulation canal, and exchange is by the heat transfer fluid of evaporator evaporation with from the heat between the fluid of outside transmission heat.
