In the racing industry safety has become an increasingly important issue. Most drivers now wear helmets and flame proof suits. It is known to use a liquid such as water to provide cooling within a suit.

SUMMARY OF THE INVENTION

The temperature inside a racecar can easily exceed 130 degrees F. and a race event can last several hours. The heat can be taxing upon a driver reducing performance. The present invention relates to a thermal electric cooler used to cool water that can be circulated to a driver's helmet, suit or seat. This might include circulating water to a vest or helmet for example. The thermal electric cooler works on the well known Peltier effect where heat is liberated and absorbed at the junction of two dissimilar metals when electricity is applied.

The present invention provides a portable, lightweight cooler that uses a minimum of auxiliary energy from the car engine to carry and power. Further advantages of the system will become apparent in the following detailed description of the invention.

The present invention further provides a thermal electric cooler for cooling a driver worn device including;

a thermal electric cooler having a first heat exchanger, an inlet for water or liquid supplying one side of the first heat exchanger; an inlet for air supplying an opposing side of the first heat exchanger. A pump moves water from a reservoir on the TE cooler from a first heat exchanger to a second heat exchanger worn by a driver. A quick release device the second heat exchanger to be detached from the TE cooler by making a single motion.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 shows a view of the cooler system;

FIG. 2 shows details of the device of FIG. 1; and

FIG. 3 shows a cross-section view of a portion of the device of FIG. 1.

DETAILED DESCRIPTION OF THE DEVICE

FIGS. 1 and 3 show views of the system 10. A portable thermalelectric cooler box 16 houses a TE cooler 18 having a heat exchanger 20 (FIG. 3) Air is drawn through inlet 12 and is exhausted from outlet 30 after picking up waste heat from the heat exchanger 20. A control 40 can be used to control the electrical power to the TE cooler. Power may be taken from a vehicle electrical system (not shown) for example. A liquid such as water contained in reservoir 24 is pumped through the thermoelectric heat exchanger 20 where it is cooled and then flows through line 50 as indicated by arrow “A” into a cooling device 52 adjacent to or worn by the driver such as a helmet, vest, suit or seat for example. The cooling device 52 includes a heat exchanger section 56 that will allow the cooled water or liquid to conduct heat away from a car driver and from the environment adjacent the driver. The water then returns through line 54 to the reservoir 24. As can be seen the reservoir 24 includes a fill cap 56 to fill the reservoir with a liquid such as water. Each line 50 and 54 is connected to the cooler box 16 by a quick connect coupling 60, 64. FIG. 2 shows details that each line 50,54 is connected to the cooler box 16 by a spring loaded quick connect coupling 60,64. These couplings 60, 64 allow for an operator to press a portion 60A, 64A and release the line so that the portable TE cooler box 16 can be disconnected from the device 52 which the driver is likely to be wearing. A bar 62 allows for simultaneous release of both quick connections 60, 64. The bar 62 allows a driver to make a single release motion, simply pressing the bar 62 down depresses both release portions 60A, 64A.

As shown in FIG. 3, water or liquid can flow from a reservoir 24 into the heat exchanger 20. Inlet air is drawn in through opening 12 by fan 14 within the TE box 16. The air can pass through an initial filter 18, to filter out dust and particulate matter. The inlet air flows through the heat exchanger 20. In the coils of the heat exchanger 20 water or liquid is cooled down and the air absorbs the waste heat and is expelled from the heat exchanger 20 through waste heat outlet 30. The air from the inlet hose 12 flows through passage 36 shown in FIG. 3 and through the warm side of the thermoelectric heat exchanger 20 and into line 50 to supply device 52. The reservoir 24 and TE cooler 16 can be partially or fully covered in insulation 72 as shown in FIG. 3.

Though not shown it would be obvious to reverse the thermal electric units 32 physically or by switching the polarity of electricity supplied to the units so that the first portion of carbon monoxide filtered air was heated instead of being cooled. This would satisfy applications where heated water would be needed.

Though not shown it would be possible to reverse the thermoelectric unit 18 physically or by switching the polarity of electricity supplied to the units so that the water would be heated instead of being cooled. This would satisfy applications where heated water would be needed.

Though not shown it is also well known to use thermostatic controls to sense a temperature or humidity of ambient air, or of the driver or of the outlet air and to control the system based on any or all of these temperatures. Also, though not shown, it would be possible to cool a stream of air in addition to the water such that the water could cool the driver's body while the cooled air would be provided to the driver to breathe.
