  • the invention utilizes commercially available thermoelectric heat transfer devices having the capability to concurrently provide heating and cooling on opposing sides of the device.
  • K&P Temp Suit is a hooded vest made from a loose-knit cotton fabric with a nylon inner liner worn by a driver while competing in an automobile race.
  • the system is supplied with the suit, an ice with chest with a pump, a timer, fittings, wire connecters and enough hose and wires to mount the components almost anywhere in the vehicle.
  • the cooling system in particular, consists of either a 16-quart or 8-quart ice chest with a built-in pump and attached hose.
  • the manufacturer of this device indicates that using the 16-quart chest the ice load will last up to four hours depending upon the cooling line insulation, test location and heat load. Temperature control is accomplished by a variable timer. This timer cycles the pump on and off at various rates thereby controlling the temperature.
  • the suit in particular, has a chin strap which keeps a cooling tube against the back of the neck thereby cooling the back of the neck. The chin strap and the vest front are fastened by velcro, thereby making fastening or unfastening simple.
  • the suit is connected to the cooling system by a quick release or dry brake connecter.
