Abstract
A vehicle heat exchanger includes heat exchangers overlapped with each other in an airflow direction. The heat exchangers include heat exchanger tubes arranged side by side with each other. The heat exchangers include outer fins interposed between neighboring heat exchanger tubes. The heat exchangers includes header pipes connecting and communicating with both ends of the heat exchanger tubes for heat-conducting media to circulate through the heat exchanger tubes and header pipes. The vehicle heat exchanger includes a reservoir in communication with one of the header pipes for reserving a heat-conducting medium. The reservoir is fixed to a header pipe of the largest one of the heat exchangers.
Claims9
A vehicle heat exchanger comprising;
- a large heat exchanger and a frontmost heat exchanger overlapped with each other in a direction of airflow, each heat exchanger comprising:
- heat exchanger tubes arranged side by side with each other;
- outer fins interposed between neighboring heat exchanger tubes;
- and
- header pipes connecting and communicating with both ends of the heat exchanger tubes for heat-conducting media to circulate through the heat exchanger tubes and the header pipes;
- a reservoir in communication with one of the header pipes for reserving one of the heat-conducting media;
- and a bracket for fixing the reservoir to the header pipe of the larger heat exchanger,
- wherein a length of the header pipes of the larger heat exchanger is longer than a length of the header pipes of the frontmost heat exchanger in an elongation direction of the heat exchanger tubes,
- wherein the reservoir is located behind a plane extending through an intake of the frontmost heat exchanger, wherein the airflow is introduced into the intake, and wherein the reservoir is located alongside the header pipe of the larger heat exchanger, and
- wherein the bracket extends toward the frontmost heat exchanger in an area beyond the overlap between the larger heat exchanger and the frontmost heat exchanger.
A heat exchanger assembly comprising:
- a condenser configured to introduce an airflow from an intake thereof and configured to condense a refrigerant of a vehicle air-conditioner by the airflow;
- a radiator located at the back of the condenser in a direction of the airflow and configured to cool an engine coolant by the airflow;
- and
- a reservoir fixed to the radiator and located behind a plane extending through the intake of the condenser for reserving the refrigerant condensed by the condenser;
- and
- a bracket for fixing the reservoir to a header pipe of the radiator, wherein the bracket extends toward the condenser beyond an overlap between the radiator and the condenser,
- wherein the reservoir is located alongside the header pipe of the radiator.
