摘要： An improved structure of cooling tower includes a fan housing with a fan disposed therein, induction openings distributed on the fan housing and located below the fan, and a diffuser stack disposed at one end surface of the fan housing. In operation, cold air is drawn into the cooling tower by the fan through inlet openings of the cooling tower so as to exchange heat with the condensing water within a water chiller. When warm and wet air is drawn out of the cooling tower and the warm and wet air outside the cooling tower is induced in through the induction openings and then is drawn out, circulation reflux of warm and wet air, which tends to occur in conventional cooling towers, can be avoided and therefore increase the efficiency of the water chiller.

摘要： This invention makes use of a electronically controlled heating device to form a region of constant high temperature on one side of the insulating material, and causes most of the heat transfer to concentrate in a longitudinal heat flux, which flows across the direction of the thickness of object-to-be-tested, to achieve the effect of one-dimensional heat transfer. When the temperatures on both sides of the insulation material being tested come to a stable state, the temperatures, the thickness of the material, and the heat flux, are measured and used to calculate the heat conductivity. The difference between the ideal two-dimensional heat transfer and the one-dimensional heat transfer can be corrected by the results of a theoretical model. The apparatus has been used to test a material with known heat conductivity. The result of the test conforms well with the expected value. Currently, the prototype which has been developed may be designed with a digital circuit which consists mainly of a single-chip microcomputer to perform PWM (Pulse Width Modulation) temperature control, temperature measurement, parameter input and coefficient calculation and displays functions.
