Abstract

A temperature-adjustment system for a vehicle includes temperature-adjustment passages and obtained by circularly connecting a battery, an inverter, a DC/DC converter, a traveling motor, and a pump that circulates the heat medium that adjusts temperatures by cooling/heating the heat generation elements, are provided. The temperature-adjustment passages and are provided with proportional valves that interrupt the flow of the heat medium and adjust the flow volume of the heat medium, an air flow-in part that introduces air into the battery temperature-adjustment passage, and a heat medium discharge part that discharges the heat medium from the temperature-adjustment passage to outside of the vehicle. The proportional valve, air flow-in part, battery, pump, and heat medium discharge part are preferably arranged in that order, and the proportional valve is closed and an air take-in valve and a heat medium discharge valve are opened.

First claim

The invention claimed is:

1. A vehicle device temperature adjustment system, comprising a temperature adjustment passage connecting in a circular manner a heat generation element, and a pump that circulates a heat medium that cools or heats the heat generation element,
the temperature adjustment passage including
a passage open or close means that interrupts a flow of the heat medium and to adjust a flow volume of the heat medium,
an air take-in means that introduces an air into the temperature adjustment passage, and
a heat medium discharge means that discharges the heat medium from the temperature adjustment passage to an outside of a vehicle, wherein
when a collision of a vehicle is detected or predicted, the passage open or close means is closed, the air take-in means and the heat medium discharge means are opened, and the pump is stopped after being driven for a predetermined time,
the predetermined time is a time required for discharging the heat medium in a section from the air take-in means to the heat medium discharge means, and
the pump, during its predetermined pumping time, drains a portion of the heat medium from the air take-in means to the heat medium discharge means along the portion in which the heat generation element is located.

2. A vehicle device temperature adjustment system, comprising a temperature adjustment passage connecting in a circular manner a heat generation element, and a pump adapted to circulate a heat medium that cools or heats the heat generation element,
the temperature adjustment passage including
a passage open or close means adapted to interrupt a flow of the heat medium and to adjust a flow volume of the heat medium,
an air take-in means adapted to introduce an air into the temperature adjustment passage, and
a heat medium discharge means adapted to discharge the heat medium from the temperature adjustment passage to an outside of a vehicle,
wherein the heat medium discharge means is structured with a pipe to be destroyed by a shock at a collision of the vehicle.

3. A vehicle device temperature adjustment system, comprising a temperature adjustment passage connecting in a circular manner a heat generation element, and a pump adapted to circulate a heat medium that cools or heats the heat generation element,
the temperature adjustment passage including
a passage open or close means adapted to interrupt a flow of the heat medium and to adjust a flow volume of the heat medium,
an air take-in means adapted to introduce an air into the temperature adjustment passage, and
a heat medium discharge means adapted to discharge the heat medium from the temperature adjustment passage to an outside of a vehicle,
wherein the air take-in means is structured with a pipe to be destroyed by a shock at a collision of the vehicle.
