Abstract
An improved cold plate structure including a plurality of like horizontally disposed, elongate, sinuously formed liquid-conducting heat transfer tubing units of stainless steel tubing having laterally spaced elongate runner portions and recurvate end portions extending between related ends of adjacent runner portions; said units are arranged in vertical stacked relationship with each other; a plurality of tie bars tightly binding the units in stacked relationship with each other with their adjacent runner and end portions in tight substantially uniform heat-conducting contact with each other and having elongate horizontal upper and lower spacer portions extending transverse the stacked units in pressure bearing engagement therewith; a body of aluminum cast about the units and tie bars and defining a flat horizontal top icing surface that is tangential with upper edges of the upper spacer portions of the tie bars and a lower surface that is tangential with lower edges of the lower spacer portions of the tie bar; and, structure connected with each end of each tubing unit arranged within and projecting from the aluminum body to connect with related fluid handling apparatus.
