Abstract
A thermal immersion circulator can comprise a heater including a hollow cylindrical main body having an inlet opening at a first end thereof and an outlet opening in a side wall thereof. The heater can include a flexible circuit board having a plurality of resistive bands controlled by controlling electronics such as TRIACs, which can be water-cooled. A thermal immersion circulator including such a heater can be used in scientific laboratories or sous vide food cooking.
Claims25
A thermal immersion circulator, comprising:
- a heater including:
- a main body having a tubular side wall, a first end, a second end spaced from the first end across a length of the main body, the tubular side wall which forms a fluid flow passage at least partially therethrough, the main body having an inlet, at least a portion of the inlet being proximate to the first end, the inlet which provides fluid communication between the fluid flow passage in an interior of the main body and an exterior of the main body, and an outlet in the tubular side wall, at least a portion of the outlet spaced relative toward the second end with respect to at least a portion of the inlet, the outlet which provides fluid communication between the fluid flow passage in the interior of the main body and the exterior of the main body;
- a heating element physically coupled to and wrapped at least partially about at least a portion of the tubular side wall of the main body;
- and
- a switch electrically coupled to control the heating element and physically and thermally conductively coupled to the tubular side wall of the main body;
- a housing sized and dimensioned to receive at least a portion of the heater;
- and
- a motor, at least a portion of the motor being mounted proximate to the second end of the main body.
