Abstract
The utility model discloses a single-ended 9-shaped pipe plate evaporator which comprises evaporating pipes and an evaporating plate. The evaporating pipes are bonded on the evaporating plate in a parallel-arrangement coiled mode, the adjacent parallel-arrangement evaporating pipes are connected at the two ends in a curve-shaped mode, the curved shape of one end connected between the adjacent parallel-arrangement evaporating pipes is in a 9 shape, the 9-shaped curves of the one ends of the adjacent evaporating pipes are arranged in a staggered mode, an axial spiral groove is formed in the inner wall of each evaporating pipe, and the further improvement is that the cross section of each axial spiral groove is in a trapezoid shape. The 9-shaped curves of the one ends of the adjacent evaporating pipes are arranged in the staggered mode, the arrangement of the evaporating pipes is more compact, and the effective length of each evaporating pipe is increased. The axial spiral grooves are formed in the inner walls of the evaporating pipes, the heat exchange area is increased, the heat exchange performance is improved, and the energy consumption is reduced.
Description
Technical field
The utility model relates to evaporimeter, particularly the tube sheet evaporimeter in the refrigerator cooling system.
Background technology
Tube-in-sheet evaporator, consist of by evaporation tube with evaporation plate that the evaporation tube outer wall links, evaporation tube is be arranged in parallel coil-like and is bonded on the evaporation plate, connect with curve shape at two ends between the evaporation tube that adjacent parallel is arranged, the end curve shape of tube-in-sheet evaporator coil portions is the U font mostly, prior art is improved a little structures, and coil portions end curve shape is 9 fonts, and evaporation tube end 9 font curved arrangement are consistent.So that evaporation tube is arranged compactlyer, increase the effective length of evaporation tube like this, thereby improved heat exchange efficiency.But the tube sheet evaporimeter heat exchange property of this structure is still undesirable, and energy consumption is still higher.
The utility model content
The utility model provides a kind of single-ended 9 font tube sheet evaporimeters that can further improve heat exchange property for the deficiencies in the prior art.
The utility model is achieved through the following technical solutions technical goal.
Single-ended 9 font tube sheet evaporimeters, comprise evaporation tube, evaporation plate, described evaporation tube is be arranged in parallel coil-like and is bonded on the evaporation plate, connect with curve shape at two ends between the evaporation tube that adjacent parallel is arranged, the curve shape of an end that connects between the evaporation tube that adjacent parallel is arranged is 9 fonts; Its improvements are: 9 font curves of adjacent evaporation tube one end are staggeredly arranged; Described evaporation tube inwall is provided with the axial screw groove.
The further technical scheme of the utility model is: the shape of cross section of described axial screw groove is trapezoidal.
The utility model compared with prior art has following good effect:
1, evaporation tube one end curve shape is 9 fonts, 9 font curves have one section circular arc to curve inwardly, 9 font curves of adjacent evaporation tube one end are staggeredly arranged, so that 9 font curved portion are avoided mutually, can make like this evaporation tube arrange compactlyer, increase the effective length of evaporation tube, thereby improved heat exchange efficiency.
2, the evaporation tube inwall is made the tank circuit, has increased the contact area of cold-producing medium and evaporation tube inwall, thereby has increased heat exchange area; Moreover, because the tank circuit can form capillary effect, make the also corresponding increase of wetted area of its inner surface, also improved heat exchange area.The increase of heat exchange area can improve heat exchange property and heat transfer rate.
