Title: Heat exchanger
Inventor: NISHIWAKI FUMITOSHI
IPC: F28F13/06
Filed: 1984-11-01
Abstract: PURPOSE:To improve the heat transfer performance of heat transfer tubes with spiral grooves in the region at high dryness in refrigerant by a method wherein the inner walls of heat transfer tubes are provided with two types of spiral grooves and the height of spiral grooves in the region at lower dryness is made smaller while the height of spiral groove in the region at high dryness in refrigerant is made much larger than the former. CONSTITUTION:The inner walls of heat transfer tubes 7, 8 are respectively provided with spiral grooves 12, 13 with triangular sections and the height (h1) of spiral groove 12 in the region of heat transfer tube 7 at low dryness in refrigerant is made smaller while the height (h2) of spiral groove 13 in the region of heat transfer tube 8 at high dryness in the refrigerant is made much larger than the former groove height (h1). Through these procedures, the higher the dryness in refrigerant and the less the flow rate of refrigerant, the easier the liquid refrigerant in the heat transfer tubes due to the capillarity in spiral grooves to be changed into circular flow or circular spray flow while forming extremely thin refrigerant film to improve the heat transfer performance.

Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To store cooling water of high temperature in a heat storage tank without being affected by engine speed. SOLUTION: When the engine load is a prescribed value or less, the calorie to be given to a temperature sensing part 13a of a thermostat 13 is reduced to keep the temperature of the cooling water around 100 deg.C.
