Cooling board

Abstract

PROBLEM TO BE SOLVED: To provide a cooling plate having a reduced size but sufficient cooling capability without worsening its yield when manufactured. SOLUTION: The cooling plate comprises a cooling pipe 3 cast and fixed into a metal material for a metal plate body for cooling drink passing therethrough. The cooling pipe is rolled in a flat helix shape with its rolling axis in the direction perpendicular to the direction of the thickness of the plate body. Portions adjacent to the helix are alternately shifted one by one or several by several in the direction of the thickness of the plate body and fixed inside the plate body.

Description

technical field [0001] The present invention relates to a cooling plate used in a cooling container (cooling saba) capable of discharging beverages such as draft beer supplied from beverage containers such as beer kegs while cooling them on site. Background technique [0002] A cooling container capable of discharging beverages such as draft beer supplied from beverage containers such as beer kegs while cooling them on site is known. In this cooling container, there is provided a cooling plate for cooling the beverage passing through it. In this cooling plate, a cooling pipe wound in a flat helical shape and cooled while passing the beverage is fixedly arranged. Cooling bodies such as ice are carried on the cooling plate to cool the plate. [0003] Small cooling plates must be used in small cooling vessels. However, when the cooling plate is miniaturized, the length of the cooling pipe inside the cooling plate is shortened, resulting in a problem that the cooling capacity...

AI Technical Summary

Problems solved by technology

Then, the heat exchange efficiency of the lower portion of the cooling pipe decreases, and there is a problem that the cooling plate as a whole cannot obtain sufficient cooling capacity.

[0004] Furthermore, when the cooling pipe is folded without gaps, when the cooling pipe is cast into the plate main body of the cooling plate, the material of the plate main body will not fully spread into the inside of the helix during casting, so that the plate main body internal voids

When a void is generated in the main body of the plate, it becomes a defective product that cannot obtain sufficient cooling capacity

For this reason, there will be a decline in the rate of high-quality products in manufacturing, and the problem of low yield
