Benefits of technology

[0016]Therefore, the combined heat exchanger system of the invention can have sufficient areas of the first and second heat exchangers, improving heat exchange effectiveness of the heat exchangers, and providing easy mounting and piping of the heat exchangers on the vehicle.
[0042]Therefore, the combined heat exchanger system can efficiently and sufficiently cool power units such as an engine, an electric motor and an inverter in addition to an air conditioning system of the hybrid electric vehicle.

Problems solved by technology

This deteriorates a heat exchange effectiveness of the heat exchanger / heat exchangers that are arranged at the rear side of the vehicle.
On the other hand, it is difficult to ensure the heat exchangers to have sufficient areas for heat exchange in the case where the number of rows is decreased by arranging the heat exchangers as many as possible on the same lateral plane of the vehicle.
Thus, as the number of heat exchangers increases, it becomes difficult to ensure sufficient heat-exchange surfaces of the heat exchangers, and the number of longitudinal-directional rows of the heat exchangers increases, thereby causing the deterioration in easy mounting on the vehicle and heat exchange effectiveness of the heat exchangers.
In addition, their piping work becomes heavy because of many pipes.

Embodiment Construction

[0045]Referring to FIG. 1 of the drawing, there is shown a first preferred embodiment of a combined heat exchanger system according to the present invention.

[0046]The combined heat exchanger system of the first embodiment is used in a hybrid electric vehicle that is equipped with an internal combustion engine 11 and an electric motor 9 as a drive unit.

[0047]The hybrid electric vehicle includes an engine cooling circuit EC for cooling a water-based coolant of the engine 11, an air conditioning circuit AC for cooling a refrigerant of an air conditioner, and a power unit cooling circuit PC for cooling another water-based coolant of a cooling device 12 of the electric motor 9 and other electric units such as an inverter 10.

[0048]Incidentally, the coolant is a working fluid to transfer heat in a cooling system, and the water is the base coolant, to which chemicals such as ethylene glycol and propylene glycol are added to lower its freezing point and raise its boiling point.

Abstract

A combined heat exchanger system includes a first heat exchanger for cooling a first cooling medium, a second heat exchanger for cooling a second cooling medium, and a compressor for compressing the first cooling medium to be supplied to the first heat exchanger. The first heat exchanger is separated from the second heat exchanger, being integrally assembled with the compressor in such a way that the first compressor can be directly and fluidically connected with the compressor. The first heat exchanger liquid-cools the first cooling medium, which is outputted from the compressor, by using the second cooling medium that is cooled by the second heat exchanger.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a combined heat exchanger system including a plurality of heat exchangers that are respectively connected with an engine and an air conditioning system for example.[0003]2. Description of the Related Art[0004]A conventional combined heat exchanger system of this kind is disclosed in Japanese Patent Applications Laid-Open Publication NO. 2010-121604, No. 2010-127508 and No. 2006-199206.[0005]The first conventional combined heat exchanger system has a first air-cooling heat exchanger (a subradiator), a second air-cooling heat exchanger (a condenser), and a third air-cooling heat exchanger (a radiator). The first air-cooling heat exchanger cools a coolant to draw heat from a heat element other than an internal combustion engine. The second air-cooling heat exchanger cools a cooling medium of an air conditioning system. The third air-cooling heat exchanger cools a coolant of an internal comb...
