Abstract
The utility model relates to a pipe shell type evaporator which comprises a metal pipe, wherein, the inner wall of which is provided with a screw thread. The metal pipe is a shaped pipe. The heat-exchange area is large, heat radiation steel wires are not used, and the heat-transfer efficiency required by the evaporator can also be obtained.
Description
Technical field
The utility model belongs to the heat-exchange apparatus field, particularly relates to a kind of shell-and-tube evaporator that is used for small-type refrigeration appliance.
Background technology
In electrical equipment such as refrigerator, refrigerator, need reach refrigeration with shell-and-tube evaporator, its principle is to allow refrigerant flow in the metal tube of evaporimeter, by heat exchange your temperature of refrigerator is descended.Simple tube shell type structure, because area of dissipation is little, its refrigeration is unfavorable, for this reason, people are connected together metal tube and a large amount of heat radiation steel wire welded, increase area of dissipation thus, improve refrigeration.The shortcoming of this structure is that steel wire is many, and the solder joint between the pipe silk is also many, has rosin joint in numerous solder joints unavoidably, very easily comes off in transit in turnover, influences refrigeration; And the place, dead angle between the pipe silk easily shelters evil people and countenance evil practices, and retains trash, brings difficulty for next procedures such as cleaning, electrophoresis, plastic-blasting, causes refrigerator in use to cause corrosion.We can say that many place's solder joints come off and the hidden danger of corrosion with regard to many places.
Summary of the invention
The technical problems to be solved in the utility model is the quality that the heat radiation steel wire has influenced evaporimeter, and the purpose of this utility model is to provide a kind of steel wire that need not dispel the heat, and can obtain the shell-and-tube evaporator of better refrigeration again.
For this reason, the technical solution adopted in the utility model is as follows: shell-and-tube evaporator, comprise a metal tube, and inner wall of metal tube is threaded; Described metal tube is a special pipe.
The screw thread of described inner wall of metal tube can be single thread, also can be meridian screw thread, rifling screw thread or other screw threads; So-called special pipe refers to that the cross section of metal tube is not circular, and it can be oblate, also can be regular hexagon, snowflake shape etc.
The utility model has adopted the metal tube of internal thread, its inner surface has spiral grooves, the big 2-2.5 of light pipe doubly in surface area was comparable, not only increased heat exchange area, spiral grooves can strengthen the stirring of convection cell simultaneously, overall heat-transfer coefficient can improve 30-50% above (GB151-1999 " lexical or textual analysis of shell-and-tube heat exchanger standard "), and energy resource consumption can reduce (steel rolling research institute of " research of internal thread tubing pulling capacity and tool parameters " University On The Mountain Of Swallows) about 10%; Adopt special pipes such as regular hexagon, oblateness, snowflake shape, can increase the appearance heat exchange area, improve heat exchanger effectiveness; Do not use the heat radiation steel wire, can reach the required heat transfer efficiency of evaporimeter yet.
Description of drawings
Fig. 1 is the structural representation of evaporimeter in the prior art.
Fig. 2 is the enlarged drawing of pipe silk weld among Fig. 1.
Fig. 3 is a structural representation of the present utility model.
Fig. 4 is the enlarged drawing of metal tube in the utility model.
Fig. 5, Fig. 6, Fig. 7 are the sectional views of the utility model metal tube.
The specific embodiment
Referring to Fig. 1, Fig. 2.Original shell-and-tube evaporator comprises metal tube 11 and heat radiation steel wire 12, and a large amount of heat radiation steel wire and metal tube are welded together, form latticed structure, and 13 places are easy to have some foreign material at pad.
Referring to Fig. 3.Shell-and-tube evaporator of the present utility model only has evaporation tube 21 and does not establish the heat radiation steel wire, has also connect the problem brought with regard to not managing wire bond.The enlarged drawing of evaporation tube 21 as shown in Figure 4, its inner surface has single thread 22.The cross section of evaporation tube 21 is regular hexagon as shown in Figure 7.
The utility model also can adopt the pipe of other shapes, oblateness as shown in Figure 5, snowflake shape shown in Figure 6.
Claims (3)
