Cooling module

Abstract

A cooling module includes a first radiator configured to cool a fuel cell stack. A second radiator is positioned in a predetermined area in front of the first radiator in an air flow direction and configured to cool an electronic component. A first condenser is positioned in the other remaining area in front of the first radiator in the air flow direction and heat-exchanged with ambient air to condense a refrigerant. A second condenser is provided within the second radiator and heat-exchanged with a coolant to condense a refrigerant. The second radiator and the first condenser are positioned alongside each other in front of the first radiator. The second condenser is provided within the second radiator.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to Korean Patent Application No. 10-2015-0025628 filed on Feb. 24, 2015 and Korean Patent Application No. 10-2016-0011454 filed on Jan. 29, 2016, the disclosures of which are incorporated herein by reference in their entirety.FIELD OF THE INVENTION[0002]The present invention relates to a cooling module and, more particularly, to a cooling module in which a second radiator and a first condenser are positioned alongside each other in front of a first radiator, and a second condenser is provided within the second radiator, thus having a reduced size, while supporting high refrigerant condensing performance.BACKGROUND OF THE INVENTION[0003]In general, in a vehicle with an internal combustion installed therein, heat generated as an engine operates is transmitted to a cylinder head, a piston, and a valve, and thus, when temperatures of these components are excessively increased, they are thermally expanded or de...

AI Technical Summary

Benefits of technology

This patent describes a cooling module that increases its cooling performance while being smaller in size. The module contains two radiators and two condensers placed next to each other, which increases the area of contact between them and enhances the cooling performance. Additionally, the positioning of the two radiators reduces the pressure drop of air, which results in higher coolant and condenser performance. The cooling module is also designed to facilitate assembly and reduce the size of the pipe configuration. Overall, this invention improves cooling performance while making the cooling module more compact and easy to assemble.

Problems solved by technology

In general, in a vehicle with an internal combustion installed therein, heat generated as an engine operates is transmitted to a cylinder head, a piston, and a valve, and thus, when temperatures of these components are excessively increased, they are thermally expanded or degraded to result in degradation of intensity, lifespan of an engine is shortened, combustion deteriorates to cause knocking or preignition to degrade an output from the engine.

Also, when a fuel cell stack is incompletely cooled, an oil film of an inner circumferential surface of the cylinder is cut, degrading a lubrication function, engine oil is changed to cause abnormal abrasion of a cylinder, and a piston is fused to an inner wall surface of a cylinder.

However, the cooling module 50 illustrated in FIG. 2 is difficult to have a sufficient condensing efficiency because a size of the condenser 30 is reduced by a region in which the second radiator 21 is formed, and the second radiator 21 also has difficulty in sufficiently securing an amount of coolant flowing therein.

However, in the configuration of FIG. 3, air heated through the condenser 30 is to pass through the second radiator 21, negatively affecting performance of the second radiator 21.

In addition, temperatures of air supplied to the second radiator 21 are significantly different according to load amounts of the condenser 30, making it difficult to secure stable performance of the second radiator 21.
