Abstract: A deodorizing apparatus for shoes, said deodorizing apparatus for shoes comprises a pair of leg portions which are to be inserted into the shoes, a joining portion which joins upper ends of the pair of leg portions at a predetermined interval, ozone generating ultraviolet lamps which are respectively received in the pair of leg portions, and a power supply which drives the ultraviolet lamps to light up, wherein each of the leg portions is formed with an ozone emitting portion for emitting ozone generated by the corresponding ultraviolet lamp, and/or an ultraviolet radiation emitting portion for emitting ultraviolet radiation of a wavelength having an ozone generating action as has been generated by the corresponding ultraviolet lamp.

Abstract: In a heat exchanger comprising a plurality of first heat-transfer elements (A) for a fluid of higher temperature and second heat-transfer elements (B) for a fluid of lower temperature joined alternately and adjacently and a suitable number of appropriately shaped fins disposed within said elements and wherein the heat exchange is performed between the fluid (a) of higher temperature and the fluid (b) of lower temperature and at least the fluid (a) is changed in phase during the heat exchange, the improvement of providing such a heat exchanger with the ability to rectify the condensate from the fluid (a) and to recover the rectified liquid, wherein the fins in the lower part of the element (A) are so arranged that the fluid (a) entering from a port into the element (A) flows upwards smoothly with contact with the liquid condensed from the fluid (a) at the upper part of the element (A), which flows down through the heat exchanger.
