Problems solved by technology

When this kind of micro-channel heat exchanger is applied to the evaporator, due to the different density of the gas-liquid two-phase refrigerant, it is difficult to distribute the gas-liquid two-phase refrigerant evenly, which will lead to uneven flow of the refrigerant in the micro-channel flat tube, affecting Heat transfer effect

Embodiment Construction

[0031] Such as Figure 1-6 Shown is a micro-channel side air outlet condenser of the present invention, which includes a first header 1, a second header 2, a flat tube 3, a partition 4, an end cover 5, a side plate 6 and a fin 7 , The first header 1 and the second header 2 are both equipped with a pressure-holding accessory 8. The setting of the pressure-holding accessory 8 can maintain the working pressure required by the first header 1 and the second header 2 and avoid The components are damaged due to pressure changes to ensure normal heat exchange efficiency, protect the first header 1 and the second header 2, and prolong the service life of the first header 1 and the second header 2. The partitions 4 are both arranged in the first header 1 and the second header 2, and the partitions 4 seal the inner cavity of the header into multiple chambers.

[0032] Notched grooves 9 are evenly distributed on the first header 1 and the notched grooves 9 are evenly distributed on the seco...

Abstract

The invention discloses a micro-channel side air-out condenser and a mounting method thereof. The condenser comprises a first collecting main, a second collecting main, a flat pipe, separation plates, end covers, side plates and fins, wherein pipe joints are arranged on the first collecting main; inlet / outlet pipes are connected with the pipe joints; mounting brackets are arranged on both the first collecting main and the second collecting main; each of the mounting brackets comprises a fixed part and a connection part; the fixed parts and the connection parts are integrated; mounting holes are formed in the fixed parts; and the connection parts are arranged on the first collecting main. The mounting method of the condenser comprises the following steps: (a) part preparation; (b) part integration; (c) preliminary splicing; (d) end sealing; and (e) airtightness detection. The micro-channel side air-out condenser is compact in structure, flexible in connection, simple to mount, stable in performance, good in airtightness, large in heat transfer area so as to enlarge the heat exchange area of the air side, high in heat exchange efficiency, energy-saving, cost-reducing and wide in applicability.

Description

Technical field [0001] The invention relates to a microchannel side air outlet condenser and an installation method thereof. Background technique [0002] Micro-channel heat exchanger, also known as parallel flow heat exchanger, is a heat exchanger in which refrigerant and refrigerant flow in a channel with a diameter less than a few millimeters. This heat exchanger is currently widely used in automobile air conditioners. [0003] The microchannel heat exchanger includes two vertically arranged collectors. A plurality of horizontally arranged flat tubes are fixedly connected between the two vertically arranged collectors. There are dozens of microchannels in the flat tubes, and the equivalent diameter of the channels is 10-1000μm, the collector tube of the microchannel heat exchanger is perpendicular to the flat tube. When this type of microchannel heat exchanger is applied to the evaporator, due to the different density of gas-liquid two-phase refrigerant, it is difficult for the...
