Abstract: A heat exchanger for exchanging heat between gasses such as air and a liquid or gaseous coolant has narrow spacing between exchanger surfaces for high efficiency. To avoid undue obstruction of gas flow due to ice buildup on the exchanger surfaces, the heat exchanger is equipped with sensors to monitor the gas flow and an actuator that widens the spacing between exchanger surfaces such that gas flow remains unimpeded. Embodiments provide for defrosting of the exchanger surfaces when an limit on spacing of exchanger surfaces is reached, and for relaxing the spacing to the original narrow spacing when defrosting is completed.

Abstract: A solids heat exchanger (10) is in the form of a shell and tube arrangement having a shell section (11) through which heated oil (12) passes and a tube section (13). A screw conveyor (14) extends along its length and has a drive motor (15). Drill cuttings or other hydrocarbon contaminated materials are fed in through an inlet (16) and then conveyed along the tube (13) where heat transfer takes place.

The apparatus aims to reduce the oil content of the solids to less than 0.5%. The solids can then simply be disposed of. The base oil can be reclaimed and reused.

Abstract: To obtain a moving body cooling apparatus which can improve cooling performance through efficient use of traveling wind produced as a moving body is running. The direction of grooves 4f formed by flat-shaped cooling fins 4c provided integrally with a base portion 4a to which semiconductor devices to be cooled are affixed is inclined from a moving direction of a car body 1 which is an example of a moving body. As the car body 1 runs, traveling wind passes through the grooves 4f as shown by an arrow C. As the length of the grooves 4f becomes shorter, pressure loss due to passage of the wind decreases, flow rate of the wind increases, and the amount of heat to be removed from the flat-shaped cooling fins 4c on both sides of each groove 4f decreases. Therefore, temperature increase in the traveling wind is reduced and cooling performance is improved.
