Abstract
A heat dissipating chimney in an apparatus for the melting and dispensing of solid and quasi-solid materials, such as thermoplastics and hot melt adhesives, is disclosed. Air convection paths are provided which control the flow of heated air from a plurality of heat sources, through the cabinet of the apparatus, eventually exhausting the heated air to atmosphere. Degradation of the performance of heat-sensitive components of the apparatus is avoided by the heat dissipating system provided by the present invention.
Claims4
An apparatus for melting solid and quasi-solid material, and for dispensing the same, comprising:
- a material receiving and melting means having at least one heat source for melting said material;
- means for transporting melted material to a delivery point, said means in communication with said receiving and melting means,
- wherein the means for transporting melted material comprises a pumping means and a prime mover means for driving the pumping means, the means for transporting melted material dissipating heat therefrom so as to create another heat source;
- electronic power and control circuitry arranged and constructed to provide and control electrical power and signals for the apparatus, the electronic controls and integration circuitry dissipating heat therefrom so as to create at least a third and a fourth heat source;
- and
- a cabinet for holding said receiving and melting means, said transporting means, and said electronic power and control circuitry, said cabinet including a venting means wherein air that is contained therein and cummulatively heated by each of the heating sources is directed through the cabinet and exhausted through at least one exhaust aperture therein.
