Abstract: Disclosed are plate-shaped fins (2) for a heat exchanger (1) having a coated film (4) formed thereon so that waterdrops can easily fall down from the surface of the plate-shaped fins, the coated film being composed of a solution containing a silicone coating film type resin compound and inorganic finely divided particles. Further, the inorganic finely divided particles are used to provide fine irregular portions on the surface of the coated film formed on the plate-shaped fins so that the area where the waterdrops come into contact with the surface of the fins is reduced.

Abstract: PURPOSE:To improve a water repellent characteristic of a formed coating film and make it rigid by a method wherein the unit structure of a water repellent coating composition is a specified three-dimensional structure and the composition is composed of silicone resin with specified R/Si ratio, organic solvent and non-organic fine particles. CONSTITUTION:The unit structure of water repellent coating composition a three-dimensional structure composed of (A) and (B) elements in an equation (1). It is composed of solution having silicone resin with R/Si ratio of 1.2 or more and 1.7 or lower, organic solvent and non-organic fine particles subjected to hydrophobic nature treatment. The surface of substrate coated with the water repellent coating composition having this configuration has an effect of water repellent of the silicone resin and has a small contact area between the surface and water droplets due to the fine irregular surface formed by non-organic fine particles and the water repellent characteristic is remarkably improved and at the same time it shows a superior machining characteristic.

Abstract: PURPOSE:To eliminate the generation of stagnation of paint and prevent the cracking cf a coated film after drying and setting by providing fine grooves near the heat transfer tube penetrating hole of a fin. CONSTITUTION:Heat transfer tube penetrating holes are bored on a plate fin 1 and fin collars 2 are raised up from the fin 1 with an equal interval while the heat transfer tubes 3 are fixed to the plate fin 1 by expanding the tubes after penetration to contact the pipes with the fins closely and the plate fin 1 is provided with fine grooves 7 near the heat transfer tube penetrating holes. Accordingly, coating 8 is stagnated once in the upper part of the heat transfer tubes of a heat exchanger, dipped into functional coating to coat it and pulled up from a dip tank, while excessive coating 9 flows along the fine grooves 7 near the heat transfer tube penetrating holes and arrives at the end face of the fin, then, drops down by the gravity of the same. According to this method, excessive coating on the surface of the fin will never be stagnated at the lower part of the heat transfer tubes and the generation of cracking of a coating film is eliminated after the coating is dried and set whereby the corrosion of a heat exchanger may be prevented.

Abstract: PURPOSE:To prevent the generation of the lumps of paints in the lower sections of fins and the cracking of films by forming inserting holes for heat-transfer tubes and grooves obliquely shaped to the lower end sections of the fins in the lower sections of the fins. CONSTITUTION:Inserting holes 17 for heat-transfer tubes and grooves 12 obliquely shaped to a lower end section 14 in the lower section of a fin are formed to the fin. Excess paints 15 on the fin pulled up from a dipping tank are transmitted on the surface of the fin and flow to the lower section 13 of the fin, and are transmitted in the groove 12 and are collected to the lower end section 14 of the fin. Since paints 15 collected at one point fall by their own weight, no liquid mass of paints is generated in the lower section of the fin. Accordingly, the generation of the cracking of a film from the lump of the film generated in the lower end section of the fin and the generation of the corrosion, etc., of the fin can be prevented even through drying and baking.

Abstract: PURPOSE:To perform the efficient feed of an odor by providing an airflow control device, an odor density control part, and an odor generating device. CONSTITUTION:Air sucked through a front grill 12 with the aid of a blower 18 flows through an air filter 14 and a heat-exchanger 15. The air containing a perfume volatilized from a perfume generating device 16 right before a discharge grill 17 is discharged in a room through the discharge grill 17 to add a perfume to a room. In this case, an air flow of air fed with the aid of the blower 18 is controlled by an airflow control device 18a so that the magnitude of an airflow level is changed along with a lapse of a time. Perfume density in a room is detected by means of a perfume density sensor 13. When the perfume density is lower than a set value, a perfume generating device 16 is driven by means of a density control part 23 and when the perfume density is high, the perfume generating device is stopped. This constitution effectively feeds a perfume to the interior of a room.
