Cooling system for a vehicle

Abstract

Disclosed is a cooling system for a vehicle, in which coolant coolant, a blend of an antifreezing solution and water flowed into a radiator generates turbulent flow when a vehicle is in a state of a critical driving mode of a vehicle for example, a hill-climbing mode, thereby enhancing heat radiating performance and reducing pressure drop amount at the same time.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation-in-part of U.S. patent application Ser. No. 11 / 640,605, filed on Dec. 18, 2006.TECHNICAL FIELD[0002]The present invention relates to a cooling system for a vehicle, in which a coolant, a blend of an antifreezing solution and water flowed into a radiator generates turbulent flow when a vehicle is in a state of a critical driving mode of a vehicle for example, a hill-climbing mode.BACKGROUND ART[0003]In U.S. Pat. No. 4,332,293 there is suggested a numerical range in that the length of a fin in a direction of air flow should be 12 to 23 mm, the pitch of the fin should be 1.5 to 3.3 mm, and the pitch of a tube should be 8.5 to 14 mm as elements of a radiator mounted within a range of a limited core mounting space so as to overcome air resistance generated as the length of the fin is lengthened in the direction of air flow in the radiator with a tube arrangement of 2 or 3 rows and reduction of heat transfer p...

AI Technical Summary

Benefits of technology

"The present invention provides a cooling system for a vehicle that includes a thin radiator that reduces production costs, enhances heat radiation performance, and reduces energy loss due to a pressure drop of the coolant. The system also includes an optimal design condition for enhancing heat radiation performance in a critical driving mode of a vehicle and reducing a coolant-side pressure drop amount. The design of the radiator is optimized to maintain heat radiation performance while reducing its weight and coolant-side pressure drop amount. The cooling system includes a thermostat for adjusting the coolant flow rate based on the engine temperature, and the coolant flows through the radiator in a turbulent flow region with a high Reynolds number. The system also includes a fin with a specific design for maximizing heat transfer rate and reducing weight. The heat exchange tube is a flat type without a dimple, and the heat exchanger is a cross flow type."

Problems solved by technology

Particularly, there are some limitations in suggesting a preferred deign object of exchanger tubes in a critical operation condition such as alpine regions with many inclines or cold or arctic regions.
