Title: Heat exchanging pipe equipped with needle-type fin and manufacture thereof
Inventor: HAMANAKA SUKEAKI
IPC: B21D53/06
Filed: 1984-06-07
Abstract: PURPOSE:To improve drainage of condensed water when a tube is employed as an evaporator and prevent flying of dew by a method wherein axial grooves are formed between a plural rows of needle-type fins provided on the flat surfaces of the hollow flat tube. CONSTITUTION:Filler 4 is loaded into spaces between plate fins 3 of the hollow flat tube 1 and slits 5, having width Ws and depth Ds, are worked in the direction orthogonal to the axial direction of the tube, thereafter, the filler 4 is molten and removed to manufacture the cantilever type needle-type fins 6. In this case, the depth Ds of the slit 5 is worked so as to be shallower than the height Hp of the plate fin 3 and whereby the groove 13, having the depth of (Hp-Ds) can be formed between the rows of needle-type fins along the axial direction of the tube. According to this method, the condensed water flows down after being collected into the groove 13 provided along the direction G of the gravity of the water, therefore, drainage may be improved. On the other hand, the water, moving into the axial direction of the tube along the flow of air 10, can not flow into the groove 13 under overriding the bank of the groove 13, therefore, the phenomenon of flying dew may be reduced remarkably.

Title: Liquid fuel combusting device
Inventor: ARAKI TAKASHI
IPC: F23N5/20
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To prevent an unburned gas from risting by providing a control device wherein the mixing rate of a fuel is forcibly increased, and at the same time, the jetting speed of a mixed gas from a flame forming part is suppressed, and the amount of air for combustion is increased so that the mixing rate of the fuel may be set at a mixing rate at the time of a normal combustion after a specified period of time has passed. SOLUTION: After waiting a fixed period of time as the specified period of time when the amount of air for combustion is made smaller than a normal time since a blower 28 for convection is operated as the starting point, the revolution number of a blower 27 for combustion is raised to a second revolution number which is larger than a first revolution number but smaller than a revolution number corresponding with the feeding amount of an electromagnetic pump 26, and the blower 27 for combustion is continuously operated only for a specified period of time. For this reason, the mixing rate of a fuel is forcibly fixed to a higher side than normal only for a specified period of time so that air based on the fuel being fed to a burner may become less, and the generation of an unburned gas during this period is reduced.
