The heat exchangeable thermovoltaic power generation system is primarily applied to the field of the thermovoltaic power generation system with a heat exchange function.

A processing method of high-quality large-diameter thin-walled metal cylinder
The invention relates to a machining method of a high-quality large-diameter thin-wall barrel body. The machining method comprises the following steps. Firstly, isothermy or hot die anti-extrusion technology is utilized, and anti-extrusion is performed on an alloy forging rod. Secondly, machining is performed on the inner and outer surfaces of a spinning barrel billet, and finish turning is performed on the inner surface of the barrel bottom of the barrel billet. Thirdly, multi-pass brute force thinning spinning is performed on the machined spinning barrel billet, and the spinning is hot spinning or cold spinning. Fourthly, intermediate heat treatment is performed on a spinning semi-finished product, and the intermediate heat treatment is annealing or solution treatment. Fifthly, the third step and the fourth step are performed repeatedly and alternatively so that finished product spinning is performed. Sixthly, scouring and cleaning are performed on the barrel body, and finished product heat treatment is performed. Seventhly, polishing of the inner and outer surfaces of the barrel body after heat treatment in the sixth step is performed, and a finished product barrel body is obtained. By adoption of the machining method of the high-quality large-diameter thin-wall barrel body to machine a large-diameter thin-wall metal barrel body without welding lines, organization is even and fine, comprehensive performance is high, the process is short, product additional values are high, and good application and popularizing prospects and certain economic and social benefits are achieved.

Glass shell absorption type adsorption refrigeration element manufacturing method equipment and products
InactiveCN102401505BLow priceHigh strengthClimate change adaptationEnergy efficient heating/coolingLinear motionAdsorption refrigeration
The invention relates to a method for manufacturing an absorptive type or adsorptive type refrigeration element for glass shell. In the method, glass is used as a container for the absorptive type or adsorptive type refrigeration element. In the absorptive type or adsorptive type refrigeration element manufactured according to the method, the closed container is vacuumized and filled with an absorbent solution or an absorbent material working medium pair, and a valve also can be arranged in the refrigeration element; and the refrigeration element comprises three function parts, namely an absorption chamber / regeneration chamber or an adsorption chamber / desorption chamber, a condensation section and an evaporation chamber, and is characterized by comprising the glass closed container. The glass tube bending equipment special for the glass shell absorptive type or adsorptive type refrigeration element is characterized in that an intermediate clamp can made vertical motion relative to an axis of a glass tube, clamps at two ends can make linear motion along the axis of the glass tube and make rotary motion relative to the axis of the glass tube. The method has the advantages that the glass container does not generate noncondensable gas, is less in deflation, resistant to corrosion and high in tightness, and the manufactured element which is in a shape like a Chinese character 'pin' can be formed at one time by hot drawing. Four embodiments are provided in the figure.
