A Peltier module comprising: thermoelectric elements in which plural p-type and n-type thermoelectric elements are alternately arranged, metal electrodes placed in both ends of the thermoelectric elements in order to connect the thermoelectric elements in series, and metal substrates on at least a part of which surfaces an insulating thin film is formed, the metal substrates being oppositely placed so as to be connected to the metal electrodes and sandwich the metal electrodes and the thermoelectric elements.

There is provided a heat sink comprising a base plate provided with a plurality grooves and concave portions, each of which has a substantially trapezoidal cross section having a flat bottom face and inclined side faces and is formed into a tapered shape, formed between the adjacent grooves by plastic deformation; and a plurality of thin-sheet fins which are inserted in the grooves and are crimped from both sides by the inclined side faces formed by the plastic deformation of the concave portion.

Heat sink, method for manufacturing same, and pressing jig

A heat sink with fins comprising a group of heat dissipating fins which comprise combination of heat dissipating fins made of at least two kinds of metals having different heat conductivity, and a metal base plate on which surface portion the group of heat dissipating fins are densely jointed.

Apparatus for detecting foreign matter in a fluid

The present invention proposes a heat pipe heat exchanger comprising a hot gas flow duct, a cold gas flow duct and a plurality of heat pipes each with spiral fins around thereof that are installed horizontally a little slanted so that an end of each heat pipe in said hot gas flow duct becomes a little lower than the other end, and that said spiral fins are winding clockwise around some of the heat pipes and counter-clockwise around some other heat pipes. This device can prevent a bias flow of the steel balls at the so-called shot cleaning process performed for elimination of dust deposited on the heat pipes by arranging a layout of the two kinds of heat pipes, namely the heat pipes with clockwise winding fins around thereof and the heat pipes with counter-clockwise winding fins, and if required, can even control the flow of the steel balls so that they gather onto the area where more dust is deposited.
