Claim:
1. A heat exchange device for heating liquid adhesive material to an application temperature suitable for an adhesive bonding application, the heat exchange device comprising: a body having an inlet configured to receive a flow of liquid adhesive material and an outlet configured to provide the liquid adhesive material to a dispensing device for the adhesive bonding application, the body comprising a generally cylindrical socket having a longitudinal length; a fluid passageway defined in said body fluidly connecting said inlet and said outlet, said fluid passageway including a thin slit section having a length along a fluid flow direction between said inlet and said outlet, a profile of said thin slit section being a continuous ring, said thin slit section having a circumference of the ring and a radial thickness of the ring transverse to the fluid flow direction, the circumference of the ring and the length being substantially greater than the radial thickness of the ring; an interior body member extending within said generally cylindrical socket and along the longitudinal length to define said thin slit section at an annular gap located between said generally cylindrical socket and said interior body member, said interior body member including a plurality of projections extending radially outwardly into contact with said generally cylindrical socket, with gaps for flow of liquid adhesive material into said thin slit section located between said plurality of projections; and at least one heating element thermally coupled with said body and configured to heat the liquid adhesive material flowing through said fluid passageway to the application temperature.
