Embodiment Construction

[0032] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] In each drawing of the present invention, the size of the structure is shown exaggerated relative to the actual size for clarity of the present invention.

[0034] In the present invention, terms such as first and second may be used to describe various constituent elements, but these constituent elements should not be limited to these terms. These terms are only used for the purpose of distinguishing one constituent element from another constituent element.

[0035]When it is mentioned that a constituent element is "linked" or "connected" to another constituent element, it should be understood that it may be directly connected or connected to the other constituent element, but there may be other constituent elements in between. Conversely, when it is mentioned that a certain constituent element is "directly connected" or "directly conne...

Abstract

The heat exchanger of the present invention comprises: a lower shell, which has a lower shell half and first and second lower cover halves located on both sides of the lower shell half; an upper shell, which is fixedly arranged on the on the lower casing, and has an upper casing half forming a casing together with the lower casing half, and a second casing provided on both sides of the upper casing half and forming a second casing together with the first lower cover half. A cover and the first and second upper cover halves of the second cover together with the second lower cover half; The two covers are fluidly connected so that the refrigerant flowing inside flows from the first cover to the second cover.

Description

technical field [0001] The present invention relates to a heat exchanger. More specifically, it relates to a heat exchanger for cooling engine cooling water. Background technique [0002] Heat exchangers used in engines such as lathe engines can be classified into two types of tube type and plate type. In the above tube heat exchanger, covers may be assembled by joining both sides of the case that accommodates the plurality of tubes through which the refrigerant flows. However, since the distance between the tube and the shell is very narrow, assembly is not easy, and there is an inconvenience that parts such as the shell and the cover need to be remade when expanding the capacity of the heat exchanger. Contents of the invention [0003] technical problem [0004] An object of the present invention is to provide a heat exchanger having a structure that is excellent in assemblability and can easily expand capacity. [0005] Technical solutions [0006] A heat exchanger...
