A plurality of projections having a specific pattern are provided on the bottom of the evaporator 10. A plurality of felt mats are respectively inserted into the spaces defined by the projections. The projections support and maintain the felt pads, respectively.

However, due to the felt mats made of an elastic material, the operation for inserting the mats into the defined spaces is annoying. Moreover, because the felt pads are in frontal contact with the projections, the flow regime that penetrates into the felt pads is not properly evaporated.

The present invention has been made in view of the above problems, and the present invention provides an evaporator capable of solving such problems.

In order to achieve the above objects, the present invention provides an evaporator comprising a chamber having, on one of its sides, an inlet connected to an outlet of a condenser, and The upper portion has an outlet connected to the inlet of the condenser, and a lower surface of the chamber is in frontal contact with a heat generating member, wherein the heat is transferred and elasticized in a meandering manner. a wall system is disposed in the chamber of the evaporator, the lower surface of the zigzag shape of the wall is in contact with the bottom surface of the chamber of the evaporator, and the felt pad is inserted into a plurality of meandering shapes of the wall The defined V-shaped spaces and the lines extend along the length of the spaces, respectively.

In other words: if the perforations or the lateral distance between the peaks in the meandering shape becomes larger by pulling the wall 204 bent in a meandering manner toward the opposite side, the meandering shape 205 The distance between the perforations or the peaks also becomes larger. In this type, if an operator positions the diameter B of the felt pad W' on the upward protrusions 205a, and the pads W' are opposite to the wall 204 that has been pulled apart When the direction of the direction is squeezed, the lateral distance between the perforations or the peaks in the wall 204 becomes smaller and the inclined portions 206 It is in frontal contact with the diameter B of the felt pad W'.
