Thermoelement heat exchange module

A thermoelement heat exchange module comprising:

• a body provided with a cooling water flow path through which cooling water flows and provided with an opening that is in communication with the cooling water flow path, the body being provided with an inlet which is formed on a first side thereof to be in communication with the cooling water flow path and into which the cooling water is introduced, and the body being provided with an outlet which is formed on a second side thereof to be in communication with the cooling water flow path and through which the cooling water is discharged;
• and
• a thermoelement having a first surface coupled to a portion where the opening of the body is formed such that the first surface is exposed on the cooling water flow path,
• wherein a portion having a relatively small hydraulic diameter in a flow direction of the cooling water exists on the cooling water flow path that connects the inlet to the outlet,
• wherein the cooling water flow path between the inlet and the outlet has a bottleneck structure in the flow direction of the cooling water,
• wherein the bottleneck structure is configured such that a protruding portion that protrudes from the first surface of the thermoelement or from a first surface of the body facing the first surface of the thermoelement is formed, and
• wherein the protruding portion is configured such that opposite sides of the protruding portion in a width direction perpendicular to a longitudinal direction that connects the inlet to the outlet in a straight line are spaced apart from side surfaces of the cooling water flow path in the width direction.
