Abstract
A cooking grill structure for utilizing the heat from deep fat fryers has a grill plate and a heat pipe extending into the cooking oil. Water is utilized as the liquid medium in the heat pipe, and condensation is distributed over the grill plate to provide uniform heating and prevent accumulated forces. Distribution is achieved by a relatively small channel that uniformly spreads the heat while preventing the production of unduly large pressure forces. To achieve greater transfer of heat from the cooking oil to the liquid medium in the heat pipe, heat transfer assistance approaches, such as fins or small diameter tubes to provide a flash boiler effect may be used. Also, more than one heat pipe may be used, and the grill plates may be interlocked to provide a continuous grill surface.
Claims12
A cooking grill for use with deep fat frying containers holding a cooking oil comprising:
- a generally flat grill plate;
- and
- mounting means to support said grill plate adjacent the top of a deep fat frying container;
- a heat pipe containing a liquid medium and extending from said grill plate into the cooking oil in the deep fat frying container to convey heat from the cooking oil to said grill plate;
- and
- a flash boiler tube associated with said heat pipe, a first end of said tube being in fluid communication with the interior of said heat pipe at the bottom thereof, and a second end of said tube being in fluid communication with the interior of said heat pipe above said first end.
A cooking drill for use with deep fat frying containers holding a cooking oil comprising:
- a generally flat grill plate;
- mounting means to support said grill plate adjacent the top of a deep fat frying container;
- a heat pipe containing a liquid medium and extending from said grill plate into the cooking oil in the deep fat frying container to convey heat from the cooking oil to said grill plate;
- and
- a second heat pipe containing the liquid medium, the bottom ends of said heat pipes away from said grill plate being interconnected by a fluid conduit.
A cooking grill for use with deep fat frying containers holding a cooking oil comprising:
- a generally flat grill plate;
- mounting means to support said grill plate adjacent the top of a deep fat frying container;
- a relatively small diameter channel formed in said grill plate below the surface thereof, branches of said channel extending to be in relatively close proximity to a major portion of the surface area of said grill plate;
- at least one heat pipe containing a liquid medium extending from said grill plate into the cooking oil in the deep fat frying container, the heat from the cooking oil vaporizing the liquid medium which is then distributed by said channel to uniformly heat the surface of said grill plate without generating unduly high pressure forces;
- and
- a flash boiler tube associated with said heat pipe, a first end of said tube being in fluid communication with the interior of said heat pipe at the bottom end thereof, and a second end of said tube being in fluid communication with the interior of said heat pipe at a point above said first end.
