An improved temperature control fluid circulating system for automatically cooling a temperature control fluid in a thermal blanket with a thermoelectric cooling device having a cold side and a hot side when powered by electricity wherein the temperature control fluid is cooled by the cold side of the cooling device and pumped to, through, and from the blanket through first and second conduits. The system includes a device for powering the cooling device with pulse width modulated electrical signals; a device for sensing the temperature of fluid flowing within each of the conduits; a device coupled to the sensing device for calculating from the sensed temperatures an indication of the temperature of the fluid flowing within the blanket; and a device associated with the powering device for modifiying the temperature of the fluid by controlling the pulse width modulation of the power supplied to the thermoelectric cooling device.
An improved temperature control fluid circulating system for automatically cooling a temperature control fluid in a thermal blanket with a thermoelectric cooling device having a cold side and a hot side when powered by electricity wherein said temperature control fluid is cooled by said cold side of said cooling device and pumped to, through, and from said blanket through first and second conduits, said improvement comprising:
An improved system for regulating the temperature of a fluid circulating through a fluid flow circuit including a blanket having a fluid passage formed therein for applying a temperature to an object disposed thereagainst, said blanket including a first conduit for receiving a flow of temperature control fluid and a second conduit for discharging said flow, and said improvement comprising:
