Embodiment Construction

[0024] The following embodiments will be used to further illustrate the present invention in conjunction with the drawings.

[0025] figure 1 , figure 2 It is the plate condenser of the present invention. The plate evaporator includes an evaporation zone 1, which is formed by a plurality of evaporative heat exchange fins 11 closely connected to realize the heat exchange between the refrigerating medium A and the refrigerating liquid B; overheating zone 2, the overheating zone 2 It is formed by closely connecting a plurality of overheating heat exchange fins 21, which are used to realize the heat exchange between the refrigerant A after passing through the evaporation zone 1 and the hot fluid C after passing through the condenser; the evaporation zone 1 and the overheating zone 2 is separated by a baffle 3, the baffle 3 is provided with a guide groove 31 for guiding the refrigerating medium A heated in the evaporation zone 1 to the overheating zone 2. The cross-sectional area o...

Abstract

The invention discloses a plate-type evaporator. The plate-type evaporator comprises an evaporating area (1) which is formed by compactly connecting a plurality of evaporating heat exchange pieces (11) for realizing heat exchange between a refrigerating medium (A) and a refrigerating fluid (B); an overheating area (2) which is formed by compactly connecting a plurality of overheating heat exchange pieces (21) for realizing heat exchange between the refrigerating medium (A) passing through the evaporating area (1) and a thermal fluid (C) passing through a condenser; the evaporating area (1) is separated from the overheating area (2) by a guide plate (3) which is provided with a guide groove (31) guiding the refrigerating medium (A) heated by the evaporating area (1) to the overheating area (2). The sectional area of the guide groove (31) is equal to the open area of guide connectors (32) at both ends. The evaporator solves the problems that current evaporator occupies a large space and has low heat exchange efficiency.

Description

Technical field [0001] The invention belongs to the technical field of heat exchanger design and manufacture, and particularly relates to a plate evaporator. Background technique [0002] At present, there are more and more high-rise buildings, hotels and business buildings in the city. As we all know, in order to bring people a more comfortable environment in public buildings, most large public buildings are equipped with central air conditioners, which can control the room temperature. Within a certain temperature range, people can feel the spring season in the building. The evaporator, as an important part of the central air conditioner, takes advantage of the easy evaporation of liquid low-temperature refrigerant at low pressure to convert the refrigerant whose pressure is reduced after passing through the throttle valve into vapor and absorb the heat of the cooled medium to achieve the purpose of refrigeration. [0003] The evaporator of the common central air conditioner in ...
