Novel evaporator plate

Abstract

The invention discloses a novel evaporator plate which is composed of a polished plate and 1 / 4 spherical wrapping bodies. The 1 / 4 spherical wrapping bodies are formed by stamping, and protrusions andsinking parts are formed in the rectangular polished plate in a crossed manner and are arranged in a square manner; the main structural parameters of the novel evaporator plate include the polished plate thickness [delta]f, the distance cf between adjacent wrapping bodies, the radius R of the wrapping bodies and the distance bf between the wrapping body and the edge of the plate; by means of the novel evaporator plate, adjacent plates are welded and supported through a pipe wall and a box, fluid between the plates flows inwards in the direction perpendicular to openings of the wrapping bodies,the special structure enables the flowing speed of the fluid between the plates to increase locally, a boundary layer is thinned, and the temperature gradient is increased; when the fluid flows through or enters the wrapping bodies, strong secondary flow is generated, and the overall performance is superior to that of same-type plates; and the overall shape of the novel evaporator plate is the same as that of an ordinary plate, and the high versatility is achieved.

Description

technical field [0001] The invention relates to a novel evaporator plate, which belongs to the technical field of heat exchange enhancement and industrial energy saving. Background technique [0002] The evaporator is a general-purpose thermal power mechanical equipment, and it is a very important one of the four major components of refrigeration. Because of its irreplaceable role in the refrigeration industry, it has developed rapidly in various fields. It has been widely used in chemical industry, food industry, pharmaceutical, aviation, air separation, petrochemical, refrigeration, air conditioning, cryogenic and other fields. [0003] The type of evaporator plate plays a decisive role in the efficiency of the evaporator. Therefore, it is essential to strengthen the theoretical research and product development of the evaporator plate so that it can play a role in a wider range of fields. But now in our country, the research and development level of evaporator plates is l...

Problems solved by technology

But now in our country, the research and development level of evaporator plates is low, and the independent property rights are limited. The plates that can be produced are very single, and the plates are the core components of the evaporator. The design of the plates will directly affect the entire evaporator. Heat transfer effect
