Temperature control system for automotive storage components

Claim 1

A system for controlling the temperature of the contents of a multiplicity of storage vessels integral with an automotive transport unit, said automotive transport unit including a fluid-cooled internal combustion engine, during periods when said internal combustion engine is not in operation, comprising: (a) a multiplicity of storage tanks, each having two end sections; (b) a like number of generally coiled lengths of pipe, each length of pipe being disposed within a separate storage tank and having two end sections, each pipe end section sealably inserted through a common end section of the separate storage tank and fitted, externally to said tank end section, to receive conduit couplings; (c) connective conduit means, coupled to respective pipe end sections and adapted to provide for serial flow through the multiplicity of coiled lengths of pipe; (d) two terminal conduit means, each having two ends, each coupled at a first end to a respective terminal pipe end section, the first terminal conduit means having interposed along its length heating and pumping means and coupled at a second end to an inlet fluid coolant line, the second terminal conduit means coupled at a second end to an outlet fluid coolant line, said fluid coolant lines being normally in communication with the internal combustion engine; (e) temperature sensing means attached to at least one of said storage tanks; (f) valve means, inserted in the first terminal conduit means, operable responsively to the temperature sensing means; (g) an external electrical power source for operating said heating and pumping means and valve means; (h) a three-way cut-off valve positioned at the junction of said inlet fluid coolant line and said second end of said first terminal conduit means; and (i) by-pass conduit means connecting the cut-off valve to the outlet fluid coolant line; whereby the fluid coolant can be optionally diverted from passage through the internal combustion engine, heated and pumped in response to the power source and temperature sensing means through at least the respective pipe coils and conduit means, to control and maintain the temperature of the contents of the respective storage vessels.

Claim 2

A system for controlling the temperature of the contents of a multiplicity of storage vessels integral with an automotive transport unit, said automotive transport unit including a fluid-cooled internal combustion engine, during periods when said internal combustion engine is not in operation, comprising: (a) a multiplicity of storage tanks, each having two end sections; (b) a like number of generally coiled lengths of pipe, each length of pipe being disposed within a separate storage tank and having two end sections, each pipe end section sealably inserted through a common end section of the separate storage tank and fitted, externally to said tank end section, to receive conduit couplings; (c) connective conduit means, coupled to respective pipe end sections and adapted to provide for serial flow through the multiplicity of coiled lengths of pipe; (d) two terminal conduit means, each having two ends, each coupled at a first end to a respective terminal pipe end section, the first terminal conduit means having interposed along its length heating and pumping means and coupled at a second end to an inlet fluid coolant line, the second terminal conduit means coupled at a second end to an outlet fluid coolant line, said fluid coolant lines being normally in communication with the internal combustion engine; (e) temperature sensing means attached to at least one of said storage tanks; (f) valve means, inserted in the first terminal conduit means, operable responsively to the temperature sensing means; (g) an external electrical power source for operating said heating and pumping means and valve means; (h) a three-way cut-off valve positioned at the junction of said inlet fluid coolant line and said second end of said first terminal conduit means; and (i) by-pass conduit means connecting the cut-off valve to the outlet fluid coolant line; whereby the fluid coolant can be optionally diverted from passage through the internal combustion engine, heated and pumped in response to the power source and temperature sensing means through at least the respective pipe coils and conduit means, to control and maintain the temperature of the contents of the respective storage vessels.
