Embodiment 1

[0023] Such as figure 1 Shown is a schematic cross-sectional view of a high-efficiency condenser cylinder according to an embodiment of the present invention. The falling film condenser includes a shell 4 , a heat exchange tube bundle 2 , an arc-shaped liquid baffle plate 3 and an air equalizer plate 6 . Wherein, the upper part of the casing 4 is provided with an inlet 1 for receiving refrigerant gas. Note that the "upper part" mentioned here includes not only the top of the housing 4 , but also the position above the top of the housing 4 . Namely: in figure 2 In the embodiment shown in , the inlet is located at the top of the housing. It can also be set at the upper position below the top of the condenser. The lower part of the housing 4 is provided with an outlet 5 for discharging refrigerant liquid. Similarly, the "lower part" mentioned here includes not only the bottom of the casing 4, but also the position above and below the bottom of the casing 4. For example: in ...

Abstract

The invention relates to a high-efficiency condenser. The high-efficiency condenser comprises a plurality of heat exchange tube bundles and a condenser shell. The upper end and the lower end of the condenser shell are provided with a refrigerating fluid gas inlet and a refrigerating fluid liquid outlet correspondingly. The heat exchange tube bundles are longitudinally mounted on the condenser shell. The high-efficiency condenser further comprises arc-shaped liquid baffles which are mounted above the corresponding heat exchange tube bundles. The two ends of each arc-shaped liquid baffle are connected with baffles at the two ends of the condenser shell. The arc-shaped liquid baffles and the corresponding heat exchange tube bundles below the arc-shaped liquid baffles are concentric. Gaps are reserved between the arc-shaped liquid baffles and the corresponding heat exchange tube bundles. The arc-shaped liquid baffles are used for guiding condensed fluid on the corresponding heat exchange tube bundles above the arc-shaped liquid baffles so as to prevent the condensed fluid formed on the heat exchange tube bundles above to from wrapping heat exchange tubes below, and local vertical scouring of refrigerating fluid gas is prevented. Compared with traditional condensers, the high-efficiency condenser has the advantages that the problem that lower heat exchange tubes are wrapped by fluid films and accordingly heat exchange is hindered is effectively solved, the heat exchange effect of the condenser is greatly improved, and the energy efficiency ratio of refrigerating units is increased.

Description

technical field [0001] The invention belongs to the technical field of air conditioning and refrigeration, and in particular relates to a high-efficiency condenser. Background technique [0002] As society has higher and higher requirements for energy saving and environmental protection, how to improve the energy efficiency ratio of air-conditioning and refrigeration equipment has become particularly important. At present, in the field of refrigeration and air conditioning, water-cooled shell-and-tube condensers are generally used as the main heat exchange equipment for large-scale central air conditioners and refrigeration units in refrigerated places. The heat exchange efficiency of the condenser directly determines the energy efficiency ratio of the refrigeration unit. Most of the existing shell-and-tube condensers for refrigeration adopt a horizontal structure, and the heat exchange tubes mostly adopt high-efficiency heat exchange tubes with outer ribs and three-dimensio...
