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, a fluid passageway defined in the body connecting the inlet and the outlet and configured to receive the flow of liquid adhesive material, the fluid passageway including a thin slit section to provide a large contact surface area of the body with a relatively small volume of liquid adhesive material, the thin slit section having at least a first portion and a second portion generally parallel to the first portion, the first portion having a first flow direction and a first length along the first flow direction, the second portion having a second flow direction opposite the first flow direction and a second length along the second flow direction, the first and second portions each further having first and second dimensions transverse to the respective first and second fluid flow directions, the respective first dimensions and the respective first and second lengths being substantially greater than the respective second dimensions, and a heating element thermally coupled with the body and configured to heat the liquid adhesive material flowing through the thin slit section to the application temperature.
