Background technique
Currently, the evaporator of refrigerator is around tubular evaparator on the market, production method is to be close to an evaporation tube
Freezer liner wall surface and clockwise or counterclockwise from the gallbladder mouth spiral winding of refrigerator to gallbladder bottom, or by gallbladder bottom spiral
It is wound to gallbladder mouth.Therefore, the refrigerant trend in tubular evaparator can be divided into two kinds, and one is types from top to bottom, i.e., from refrigerator
Gallbladder mouth flow to gallbladder bottom；Another kind is type from bottom to top, i.e., from gallbladder underflow to gallbladder mouth.
At present on the market in freezer product on sale, although the evaporator of both refrigerants flow direction has application, it is
Single flow direction.For a refrigerator, refrigerant in evaporator flow direction or from top to bottom or from bottom to top.Two kinds of streams
To cutting both ways: type flows to from bottom to top, and the flowing of refrigerant is similar to the flowing that helix tube rises section in evaporator；From upper and
Mo(u)ld bottom half flows to, and refrigerant flowing is then similar to the flowing of helix tube decline section in evaporator.Helix tube rises the heat exchange effect of section
