ME-GI Strengthen the air tightness method of heat exchanger of fuel supply system for ME-GI engine

摘要

The present invention relates to an airtightness reinforcing method for a heat exchanger. According to the present invention, the airtightness reinforcing method for a heat exchanger has: a body having an inner space; and multiple spaces divided by multiple partitions formed to be lengthwise in a longitudinal direction of the body in the body, wherein a flow path in which a fluid can flow to the other space divided by the partition is formed on both ends of the partition. An inlet in which the fluid flows into the body and an outlet are formed on both sides of the body. So, after the fluid passes through the space divided by the multiple partitions in order as flowing inside through the inlet of the body, the fluid is discharged to the outside through the outlet of the body. Specifically, both ends of the longitudinal direction of the body are opened, and the multiple partitions mounted on the inside of the body are formed to be shorter than the body. So, layer level difference is generated between the body and the partition, and a sealing unit for reinforcing airtightness is mounted on the inner circumference of the body and an end of the partition through an opening unit formed on both ends of the body. So, the fluid flowing inside through the inlet of the body is not leaked to the both ends of the partition and is discharged to the outside through the outlet of the body after moving in order through the flow path formed in the partition. According to the present invention, the airtightness reinforcing method for a heat exchanger can improve heat exchange efficiency by excellently maintaining the airtightness when the fluid flows even if a high pressure is generated. Therefore, the airtightness reinforcing method for a heat exchanger can remarkably facilitate an installation work by having a simple structure of the sealing unit maintaining the airtightness.
