Heat exchanger having different flowing paths

Abstract

A heat exchanger includes a number of plate sets disposed one above the other or superposed with each other, and each plate sets includes an upper plate and a lower plate for forming one or more conduits between the upper and the lower plates, and for forming one or more ducts between the lower and the upper plates of different plates, the plates include an opening communicating and coupled to the conduits for receiving one heat medium, and an orifice communicating and coupled to the ducts for receiving a different heat medium and for separating the heat media from each other, and for allowing the heat media to have different flowing quantity from each other.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a heat exchanger, and more particularly to a heat exchanger having two or more different or uneven fluid flowing paths or passages having different cross section areas or different volumes for guiding and allowing the heat medium and / or other heat exchanging fluids to flow through the fluid flowing paths or passages with different flowing speeds and / or different contact areas, and for facilitating the heat exchanging effect. [0003] 2. Description of the Prior Art [0004] Typical heat exchangers comprise a receptacle including a chamber formed therein for receiving a heat medium, such as water or fluid, and an inlet and an outlet provided therein for allowing the heat medium or water or fluid to flow into and out of the chamber of the receptacle. The receptacle further includes a number of plates or boards or housings disposed therein, and superposed with each other, and each having a ...

AI Technical Summary

Benefits of technology

"The present invention provides a heat exchanger with multiple fluid flowing paths or passages that have different cross-section areas or volumes. This allows the heat medium and other fluids to flow through the paths with different flowing speeds and contact areas, thereby facilitating the heat exchanging effect. The heat exchanger includes two sets of plates with wavy structures and depressions / bulges that create the conduits and ducts for the fluids. The depressions and bulges have triangular and trapezoidal cross-sectional shapes. The technical effects of the invention include improved heat exchanger efficiency, reduced pressure drop, and improved fluid flow control."

Problems solved by technology

However, the heat dissipating or absorbing or exchanging rate of the different heat exchanging fluids, such as water, heat or cold media, or the like may be different from each other, such that the heat exchanging rate between the different heat exchanging fluids may be different, and such that the heat exchanging effect may not be facilitated.
