Abstract
A heater includes an aluminum die cast body defining an enclosure and an adaptor block. A heating element within the enclosure activates, under control of an associated heat sensing device, a heating element within the enclosure to transfer heat energy into the adaptor block. The adaptor block, including features specific to a given mechanical device, e.g., pneumatic valve or pump, transfers the heat energy into the mechanical device to avoid a frozen condition resulting from, for example, sudden expansion of air when passing through the device.
Claims2
A valve heater for delivering heat energy into a separate valve, the valve having a mounting site, the heater comprising:
- a heat conducting body, said body including at least an adapter block portion and an enclosure portion selectively attachable and detachable relative to the other, said adapter block portion of said body including a mounting surface adapted to be matingly corresponding in shape to a mounting site of a valve, said enclosure portion including a heat dissipation surface, said adapter block portion including a heat collecting surface, said heat dissipation surface and said heat collecting surface being held in face-to-face relation, said heat dissipation surface comprising a first coating forcing heat transfer thereat away from said enclosure portion, said heat collecting surface comprising a second coating forcing heat transfer thereat into said adaptor block portion;
- a heating element bearing against said body, said enclosure portion containing said heating element;
- and
- a control element selectively activating said heating element to deliver heat energy into said body and into a valve when said valve heater is mounted to a valve.
In combination, a valve and a separate valve heater, the valve undergoing temperature drop during operation and including a mounting site, the valve heater comprising:
- a heat conducting body, said body including at least an adapter block portion and an enclosure portion selectively attachable and detachable relative to the other, said adapter block portion of said body including a mounting surface adapted to be matingly corresponding in shape to said mounting site of said valve, said enclosure portion including a heat dissipation surface, said adapter block portion including a heat collecting surface, said heat dissipation surface and said heat collecting surface being held in face-to-face relation, said heat dissipation surface comprising a first coating forcing heat transfer thereat away from said enclosure portion, said heat collecting surface comprising a second coating forcing heat transfer thereat into said adapter block portion;
- a heating element bearing against said body, said enclosure portion containing said heating element;
- and
- a control element selectively activating said heating element to deliver heat energy into said body and into said valve when said valve heater is mounted to said valve.
