Heat exchanger for vehicle

Abstract

The invention discloses a heat exchanger for a vehicle which includes: a housing having an interior space; a header installed at one end of the housing and having a first fluid inlet manifold; a second fluid inlet manifold; and a second fluid outlet manifold; and a heat exchange core installed in the interior of the housing and having a plurality of core elements spaced apart from each other. Theplurality of core elements are coupled to the header, and a plurality of first fluid passage, through which the first fluid passes, is respectively formed between the adjacent core elements. Each of the core elements has a second fluid passage, through which the second fluid flows, an inlet of the second fluid passage communicates with the second fluid inlet manifold, and an outlet of the second fluid passage communicates with the second fluid outlet manifold.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims the benefit of priority from Korean Patent Application No. 10-2016-0170232 filed in the Korean Intellectual Property Office on December 14, 2016, the entire disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to a heat exchanger for a vehicle, and more particularly, to a heat exchanger capable of improving heat transfer performance between two or more fluids. Background technique [0004] A heat exchanger is a device that transfers heat between two or more fluids. Heat exchangers can be used in various industrial fields such as vehicles, boilers, ships and facilities. [0005] Such heat exchangers include various types such as pin-and-tube heat exchangers, shell-and-tube heat exchangers, pin-type heat exchangers, and the like. [0006] The pin tube type heat exchanger can be manufactured simply, but the durability of t...

Problems solved by technology

[0008] At the same time, due to the excellent high-pressure resistance performance and component reliability of the shell-and-tube heat exchanger, the shell-and-tube heat exchanger can be widely used, and it can ensure a generally large installation space in factories or ships, so the shell-and-tube heat exchanger The heat exchanger can be used unlimitedly, but due to the relatively narrow installation space in the vehicle, when applying the shell-and-tube heat exchanger, the degree of freedom in design, the reliability of components, and the convenience of maintenance and repair have to be considered

[0009] Thus, in the shell-and-tube heat exchanger according to the related art, since the high-pressure (not less than 30 bar) coolant passes through the inner space of the case, the case must be a pressure-resistant container having sufficient pressure resistance, and the case The outside of the body has to be insulated separately to prevent the heat recovered from the hot fluid from dissipating outside, so shell and tube heat exchangers are expensive to manufacture

[0010] In addition, as hot fluid (such as exhaust gas or EGR gas) passes through the heat exchange tubes of a conventional shell-and-tube heat exchanger, particulate matter (PMs) can adhere to the inner surface of the heat exchange tubes, thus, due to the internal is clogged, the heat exchange performance becomes very low

[0011] In addition, according to the conventional shell-and-tube heat exchanger, the heat exchange tubes installed in the shell cannot be easily separated, and therefore, pollutants such as particulate matter cannot be easily cleaned
