AI Technical Summary

Benefits of technology

The present invention relates to a condenser for use in a vehicle, which is designed to improve air cooling efficiency and performance. The condenser includes a condensation part, a reservoir tank, and a supercooling part that are integrated in a single unit. The supercooling part cools a liquid coolant that is discharged from the condensation part, using a heat exchange between the coolant and the atmosphere. The supercooling part is designed to improve air cooling capability and efficiency, even in situations where the vehicle is stopped or moving slowly. The layout of the condenser is also designed to improve installation and performance.

Problems solved by technology

1. Even if the coolant is cooled with the supercooling part thereof; it is not possible to cool the coolant below a temperature of the atmosphere that is external thereto, and thus, it would not be possible to achieve an improvement of an air cooling capability or an air cooling efficiency in a circumstance wherein a space for an installation of the conventional condenser for use in the vehicle thereof is limited;
2. A heat exchange performance arising from a velocity whereat a vehicle travels, or, put another way, a heat exchange performance arising from a wind velocity of a wind that is caused by a travel of a vehicle, varies, and thus, the air cooling capability or the air cooling efficiency declines in a circumstance such as when the vehicle is stopped or moving slowly, as in a traffic jam; and
3. In a circumstance wherein an overall surface area for a heat exchange is not changed, enlarging a surface area of the supercooling part thereof causes a surface area of the condensation part thereof to be reduced, and thus, a condensation performance thereof declines as a consequence thereof. Conversely, enlarging the surface area of the condensation part thereof causes the surface area of the supercooling part thereof to be reduced, and thus, a supercooling performance declines as a consequence thereof.

Abstract

A condenser for use in a vehicle (A1) comprises, in an integrated manner, a condensation part (4), which cools a coolant that is discharged, at a high temperature and a high pressure, to the condensation part (4) from a compressor (1) of a refrigeration cycle, by radiating heat from the coolant by way of a heat exchange between the coolant and the external atmosphere, a reservoir tank (5) that stores the coolant that has been liquefied by the condensation part (4), and a supercooling part (6), which cools the liquid coolant that is discharged to the supercooling part (6) from the reservoir tank (5) at high pressure. The supercooling part (6) is configured to cool the liquid coolant that is discharged to the supercooling part (6) from the reservoir tank (5) at a high pressure by way of a heat exchange, which does not employ a radiator fin, between the high pressure liquid coolant and a low pressure coolant that is discharged from an evaporator (3) of the refrigeration cycle.
