Cold plate and method of making same
First Claim
1. A cold plate including a cast aluminum body having vertically spaced horizontal top and lower surfaces and vertical outside surfaces about and between the perimeters of the top and lower surfaces;
- a plurality of like vertically stacked tubing units each including elongate inlet and outlet tubes with inner and outer end portions, an elongate horizontal sinuously formed heat transfer tube with inlet and outlet ends;
couplings connecting the inlet and outlet ends of the heat transfer tube with the inner end portions of the inlet and outlet tubes;
a plurality of spaced tie bars engaged with the stacked heat transfer tubes and having elongate upper and lower spacer portions extending transversely across and in vertical pressure engagement with the upper-most and lower-most heat transfer tubes and holding those tubes in substantial uniform pressure bearing and heat transfer engagement with each other;
said plurality of like vertically stacked tubing units are positioned within the aluminum body with the outer end portions of the inlet and outlet tubes projecting freely outwardly therefrom and with the top and lower surfaces of the body on planes that are coincidental with the planes on which the upper and lower edges of the upper and lower spacer portions of the tie bars occur.

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.
