The present invention relates to a seat or chair cooling apparatus. In an embodiment the seat cooling apparatus cools the back of a user without the need of forced air. The seat cooling apparatus includes an array of conduits held in place by a set of supports to form a heat exchanger. Heat from the contact surfaces is removed by free convection, an upward air movement due to density difference. When the seat cooling apparatus is in the preferred substantially vertical arrangement, the warm air exiting the conduits is replaced by cooler air entering the conduits. A seat securing attachment secures the heat exchanger components to a seat. The seat cooling apparatus shapes into the back of the user to provide comfort that is effective in cooling. The seat cooling apparatus can be light weight, portable, and occupies little space, can be quickly installed and removed, easily cleaned and is very low cost to manufacture. In another embodiment, the seat cooling apparatus is easily connected to a forced air cooling source to increase the cooling rate if desired by the user.

1. A portable seat cooling apparatus for a user adapted to attach to a seat, comprising:an array of spaced apart conduits defining passages wherein air can freely move between the array of spaced apart conduits when the user rests against the apparatus; supports spaced from each other and attached to the array of conduits; and a securing attachment attached to the array of conduits and/or the supports to secure the apparatus to the seat and wherein air moves by convection through the passages to remove heat transferred through the array of conduits when the apparatus is secured to the seat. 2. The portable seat cooling apparatus of claim 1, wherein the array of spaced apart conduits comprises parallel spaced apart deformable tubing and the supports are attached to the opposing ends of the array of spaced apart conduits.3. The portable seat cooling apparatus of claim 1, wherein the supports and the array of spaced apart conduits are made of a flexible and/or deformable material that allows the array of spaced apart conduits and the supports to flex, move, and conform to the user's back when the apparatus rests between the seat and the user.4. The portable seat cooling apparatus of claim 1, further comprising a set of collars wherein each collar is fastened onto the outer end of a corresponding conduit to prevent the set of supports from moving relative to the array of spaced apart conduits.5. The portable seat cooling apparatus of claim 1, wherein the array of spaced apart conduits and supports define interior corners, wherein the securing attachment includes a set of straps wherein each end of the V-shaped strap is attached to an interior corner.6. The portable seat cooling apparatus of claim 1, wherein the securing attachment includes a set of rings that attach a V-shaped strap to one end of the array of spaced apart conduits and/or one support and another set of ring attach the other V-shaped strap to the opposite end of the array of spaced apart conduits and/or the other support, wherein each V-shaped strap is coupled to and decoupled to a cord such that the apparatus can be secured and removed from the seat.7. The portable seat cooling apparatus of claim 1, wherein heat is removed by free convection through an upward air movement without external aid due to an air density difference in the passages of the array of spaced apart conduits.8. The portable seat cooling apparatus of claim 1, further comprising a forced air stream, wherein heat is further removed by forced convection with the aid of the forced air stream blowing through the passages of the array of spaced apart conduits.9. The portable seat cooling apparatus of claim 1, wherein the securing attachment secures the apparatus vertically to the back rest of the seat with clearance to allow air to enter into the bottom openings and wherein the air exits from the top openings of the array of spaced apart conduits and wherein the securing attachment includes a holding strap brought beneath the bottom of the back rest and the end of the holding strap is wrapped over the top of the back rest.10. The portable seat cooling apparatus of claim 1, wherein the securing attachment includes a set of hooks on the ends of an elastic cord engaging rings wherein the elastic cord provides sufficient tension to hold the apparatus in place to the back rests of various sizes and the apparatus can easily be removed by quick disengagement of the hooks from the rings.11.
