Benefits of technology

"The invention is an oil cooler that uses an embossed plate to increase heat exchange efficiency. The oil cooler has an oil guiding arrangement and an air guiding arrangement that work together to cool down the oil before it exits. The embossed plates guide the oil to flow in a three-dimensional movement within the oil passageway, creating a larger surface area for heat exchange with the air. The invention is advantageous in that it saves space and weight, and is easy to fabricate and assemble."

Problems solved by technology

More complex projections are difficult to form.

Embodiment Construction

[0025]Referring to FIGS. 1 to 3 of the drawings, an oil cooler for exchanging heat with oil according to a preferred embodiment of the present invention is illustrated, wherein the oil cooler comprises and oil guiding arrangement 10 for guiding oil flowing from an oil inlet 11 to an oil outlet 12, and an air guiding arrangement 20 for guiding a medium, preferably fresh air, to exchange heat between the oil and the air of the medium, so as to cool down the oil before the oil existing the oil outlet 12.

[0026]The oil guiding arrangement 10 further comprises a plurality of oil passageways 13 communicatively extending from the oil inlet 11 to the oil outlet 12 of the oil guiding arrangement 10. The oil passageways 13 are preferably to be spacedly stacked with each other, so that the oil is guided to longitudinally flow from the oil inlet 11 to the oil outlet 12. In particularly, the oil passageways 13 are parallel with each other.

[0027]The air guiding arrangement 20 comprises a plurality...

Abstract

An oil cooler includes an oil guiding arrangement an oil guiding arrangement and an air guiding arrangement. The oil guiding arrangement has an oil inlet, an oil outlet, and a plurality of oil passageways communicatively between the oil inlet and the outlet and spacedly being stacked apart from each other. The air guiding arrangement has a plurality of air guiding passageways alternating with the oil passageways and arranged for guiding air flowing through the air guiding passageways to heat exchange with the oil so as to cool down the oil before exiting at the oil outlet. A plurality of embossed plates are disposed in the oil passageways respectively for creating a three-dimensional oil movement within the oil passageway to heat exchange with the air, so as to enhance the heat exchange efficiency.

Description

BACKGROUND OF THE PRESENT INVENTION[0001]1. Field of Invention[0002]The present invention relates to an oil cooler, and more particularly to an external oil cooler having an embossed plate in the oil chamber to increase the heat exchange efficiency.[0003]2. Description of Related Arts[0004]Oil cooler is a heat exchanger which uses a medium with lower temperature to exchange heat with the oil. Accordingly, the medium is preferably air, and the oil is intended to include engine oils, transmission fluids, hydraulic fluids, or other fluid.[0005]The oil is cycling within an enclosed loop. In a portion of the loop, the fresh air contacts with the outer wall of the loop. Since the temperature of the fresh air is lower than the temperature of the oil, heat exchange happens between the fresh air and the oil through the wall of the loop. The heat is carried away by the fresh air, and the oil is cooled.[0006]In order to increase the efficiency of heat exchanging, it is necessary to maximize th...
