<p>Fluid heat transfer system (10) including a motor (14) and a tank (12) located in adjacent compartments. The motor (14) is operatively connected to a rotatable shaft (16) extending into the tank (12) having an opposed end (62) connected to an impeller (28) for circulating a heated working fluid (21) through the system (10). A hollow tube (18) surrounding the rotatable shaft (16) extends from the motor (14) into the tank (12) and forms a leak proof seal between the tube (18) and the tank (12) so that the fluid (21) will not leak outside of the tank (12). The fluid (21) circulates through numerous tubes (20) positioned within the tank (12) having respective inside surfaces (70) which are each provided with a heating unit (22) therein for collectively heating fluid (21) as the fluid (21) passes between each respective inside surface (70) and heating unit (22). The tubes (20) have dimples (71, 72, 73, 75) formed therein for more efficiently heating the fluid (21).</p> |
