Title: Plate heat exchanger
Inventor: TSUNO KATSUYUKI
IPC: F28D9/00
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To obtain a heat exchanger comprising a plurality of plates laminated through an interval in which the heat exchanging performance as a condenser is enhanced by making one sort side of a heat transfer plate shorter than the other short side and arranging the longer short side above the shorter short side. SOLUTION: Water flows into a plate heat exchanger 1 from the water inlet 5 thereof and flows out from the water outlet 4 thereof after exchanging heat therein with high temperature high pressure refrigerant. The refrigerant delivered from a compressor in the form of high temperature high pressure refrigerant gas flows into the heat exchanger 1 from the refrigerant inlet 2 thereof and flows in the direction opposite to the water flow. The refrigerant is condensed through heat exchange with water flowing through a water channel to produce liquefied refrigerant which flows out from a refrigerant outlet located on the side opposite to the water inlet 5.  One sort side of a heat transfer plate is made shorter than the other short side, e.g. the cross-section channel area of the heat exchanger 1 is halved from the upper part toward the lower part, in order to suppress lowering of the flow rate of refrigerant thus enhancing heat exchanging performance.

IPC: B63H5/07
Filed: 1985-03-04
Abstract: PURPOSE:To reduce production cost of a propeller system by facilitating both machining and maintenance with air outflow members coaxially arranged on a shaft bracket located in front of the propeller and with air supply ducts arranged on the shaft bracket for supplying compressed air to the air outflow members. CONSTITUTION:In case it is necessary to cover an entire propeller 1 with air bubbles for the purpose of reducing propeller noise propagated in the water, the entire propeller 1 can be completely covered with air bubbles 9 by supplying compressed air through an air pipe 6 to the air outflow device 5 arranged on the shaft bracket 2 just in front of the propeller. Thus, noise propagated into the water can be completely enveloped with air bubbles, propagation of the noise into the water can be reduced, and both machining and maintenance of the propeller are facilitated, resulting in reduced cost. Further, since the air pipe is not arranged through the propeller itself, the thickness of the propeller blades can be reduced for preventing propeller efficiency from being reduced and flow of water to the propeller is made laminar by means of a radial blade 5-2 resulting in improved propelling efficiency.
