Abstract
The utility model discloses and a kind ofly revolve wing evaporimeter with heater strip, spiral fin coil is bent into the snakelike lamination that reverses from centre and forms upper and lower two-layer formation Screwy fins evaporator, described Screwy fins evaporator is two-layer up and down exists certain angle for non-parallel configuration, linear heat silk is wrapped in the centre of each pitch of helical fin, and the two ends of Screwy fins evaporator are fixed by end plate and Spiral Fin Surface riveted.The snakelike helical fin pipeline made is carried out turning round layer and forms two-layer up and down by the technical program, two-layer up and down exist certain angle for non-parallel configuration, by this angle one be ensure ventilation effect, two is accelerate rate of heat exchange, but also on the pipeline at the neutral place of two helical fins, be provided with heater strip, more effectively powerful defrost effect.
Description
Technical field:
The utility model relates to and a kind ofly revolves wing evaporimeter with heater strip, is specially adapted to refrigeration for refrigerator industry wind-cooled evaporator uses.
Background technology:
At present along with the development of refrigeration industry, luxurious wind cooling refrigerator is occuping market leading position gradually, and whole refrigerator industry requires more and more higher to the demand of wind-cooled evaporator and exchange capability of heat.Wind-cooled evaporator main is on the market evaporator fin at present, general employing aluminum pipe aluminum fin-stock structure, this product is divided into again: drawing expansion type evaporator fin and plug-in type evaporimeter, the product heat-exchange capacity of this two large class is substantially fixing, area of dissipation also can only be confined on fin and pipeline surface foundation, be difficult to increase exchange capability of heat again on the basis not changing small product size, wind cooling refrigerator is that wind-cooled evaporator is put into refrigerator body inside, the effective storage area of refrigerator can be occupied, therefore, wind-cooled evaporator volume is less, heat transfer effect is better, more be conducive to the development of wind cooling refrigerator, this kind of evaporator heat exchange efficiency and large change can not be had, seriously constrain the development of wind cooling refrigerator, moreover the heater strip on wind-cooled evaporator is generally arranged on evaporator fin surface, defrost weak effect, not energy-conservation.
Summary of the invention:
Task of the present utility model proposes a kind of compact conformation, and high a kind of of heat exchange efficiency revolves wing evaporimeter with heating wire structure.
Task of the present utility model completes like this, a kind ofly revolve wing evaporimeter with heater strip, it is characterized in that: spiral fin coil is bent into the snakelike lamination that reverses from centre and forms upper and lower two-layer formation Screwy fins evaporator, described Screwy fins evaporator is two-layer up and down exists certain angle for non-parallel configuration, linear heat silk is wrapped in the centre of each pitch of helical fin, and the two ends of Screwy fins evaporator are fixed by end plate and Spiral Fin Surface riveted.Described angle is positioned at the centre of upper and lower two-layer helical fin contact surface.Described heater strip is linear.Described helical fin is chosen as metal and makes, helical fin thickness 0.1-10mm, helical fin height 3-12mm, pitch size 3mm.
The utility model has following effect: the snakelike helical fin pipeline made is carried out turning round layer and forms two-layer up and down by the technical program, two-layer up and down exist certain angle for non-parallel configuration, by this angle one be ensure ventilation effect, two is accelerate rate of heat exchange, but also on the pipeline at the neutral place of two helical fins, be provided with heater strip, more effectively powerful defrost effect.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model; Fig. 2 is the left side view of Fig. 1; Fig. 3 is stereogram of the present utility model.
Drawing illustrates: 1, pipeline, 2, helical fin, 3, heater strip, 4, end plate, 5, fixing hole.
Detailed description of the invention:
Embodiment is described in detail in conjunction with above accompanying drawing, helical fin 2 etc. is spirally wound on pipeline 1, form spiral fin coil, furtherly: make pipeline and be chosen as metal material making, optional aluminium, copper, iron etc., pipeline external diameter is φ 3-12mm, helical fin is chosen as metal and makes, preferred aluminium, copper, iron etc., helical fin thickness 0.1-10mm, helical fin height 3-12mm, pitch size 3mm, pipeline and helical fin can be combined, fin integral heat sink area can be made to increase owing to adopting the wrinkle of helical fin structure helical fin, but also keep the existing overall dimensions of evaporimeter, heat exchange efficiency will be improved further, as shown in Figure 1, the spiral fin coil formed is bent into snakelike, snakelike spiral fin coil carries out torsion lamination and makes from centre, upper and lower two-layer formation Screwy fins evaporator, as shown in Figure 3, two-layer up and down exist certain angle a for non-parallel configuration, described angle is positioned at the centre of upper and lower two-layer helical fin contact surface, as shown in Figure 2, due to the existence of angle, slightly can adjust angle, under the prerequisite of a small amount of increase evaporimeter thickness, greatly accelerate speed air flow, coordinate pore and wrinkle on air-cooled fan and helical fin, improve heat exchanger effectiveness.
In order to solve a Screwy fins evaporator defrost difficult problem further, as shown in Figure 1, pipeline in the middle of each pitch of helical fin 2 is wound with the heater strip 3 of uniform pitch, described heater strip is linear heat silk, shape such as electric wire can bend, heater strip directly contacts with the pipeline 1 on Screwy fins evaporator, and is positioned at the centre of every section of helical fin, evenly defrost also can increase defrost effect to greatest extent.
After being assembled by the Screwy fins evaporator of foregoing description, as shown in Figure 1, fixed by end plate 4 and Spiral Fin Surface riveted at the two ends of evaporimeter, end plate 4 has fixing hole 5, the both sides of each end plate respectively have a fixing hole, whole Screwy fins evaporator has 4 fixing holes, by fixing hole and refrigerator body inside fixing, thus solve Screwy fins evaporator and fix the problems such as station.
