Heat shrink tool holder cooler

A method of cooling heat shrink tool holders comprising the steps of:

• a) placing heated tool holders in a cooling tray;
• b) accessibly removably mounting the cooling tray in an exteriorly accessible cooling chamber of a cooling unit;
• and
• c) propelling ambient temperature air over the cooling tray to thereby cool the tool holders to ambient temperature.

A cooling unit for reducing a temperature of at least one heat shrink tool holder, the cooling unit comprising:

• a housing defining a cooling chamber;
• a cooling tray removably mounted within the housing and having a plurality of receptacles formed therein which are each configured to accommodate a heat shrink tool holder;
• a blower disposed within the housing proximate the cooling tray for propelling a flow of ambient temperature air over the cooling tray to thereby cool the heat shrink tool holder;
• a damper disposed within the housing between the cooling chamber and the blower for selectively regulating the flow of air over the cooling tray disposed within the cooling chamber;
• and
• wherein the blower is an axial fan having an axial inlet in fluid communication with the ambient temperature air and a radial outlet disposed adjacent the damper.
