Technical field
The utility model relates to a kind of evaporator for refrigerator.
Background technology
Lower position as drawer in the refrigerating chamber of refrigerator is provided with refrigerating evaporator, is used for refrigerating chamber is lowered the temperature.This refrigerating evaporator is made of coil pipe and the heat radiation sheet material that is fixed on the coil pipe usually, when refrigerant flows in coil pipe, with the external world heat exchange takes place by coil pipe, heat radiation sheet material refrigerating chamber is lowered the temperature.Fig. 1 shows the structure of the refrigerating evaporator of prior art, that is, the trend along coil pipe on heat sink is provided with the effective heat sink fin of a plurality of fixed disks, and coil pipe is clipped between the adjacent heat sink fin and is maintained fixed with heat sink.Heat sink adopts the cotton ginning heat sink usually.
The prior art problems point:
1. owing to only be in line between coil pipe and the heat sink and contact, therefore, hot conduction efficiency is lower,, has the big problem of thermal resistance that is.And coil pipe is understood and heat sink generation slit in actual production, carries out the heat conduction in this case, and thermal resistance is bigger.
2. the area of dissipation of heat sink is big inadequately, and increases area of dissipation, just must strengthen the area of heat sink, and this is subjected to the restriction of refrigerator size.
3. because the air flow property at heat sink, coil pipe place is relatively poor, the coefficient of heat transfer is very little.
4. the enabling capabilities of stamping forming cotton ginning aluminium sheet is limited, mutability.The simple fin that leans on is fixed on coil pipe on the heat sink, after the long time, and the fin easy deformation, coil pipe also will become flexible, and can not play good fixation.
The utility model content
In view of this, main purpose of the present utility model is to provide a kind of evaporator for refrigerator, to realize that heat conduction efficiency increases between heat sink and the coil pipe, increases the effect of radiating efficiency.

The specific embodiment
Introduce the production process and the structure of evaporator for refrigerator in detail below in conjunction with figure.Fig. 2 is a making flow chart of the present utility model.As shown in the figure, after the aluminium sheet punch forming aluminium sheet is carried out flanging and be processed to form described heat sink 3, then and carry out pressing through the coil pipe 1 of brake forming and form evaporator for refrigerator.
Fig. 3 is the structural representation of the utility model evaporator for refrigerator.As shown in the figure, evaporator for refrigerator provided by the utility model comprises coil pipe 1 and heat sink 3, on heat sink 3, be formed with the outwards outstanding fin 2 of many groups, coil pipe 1 is maintained fixed by 2 clampings of many groups fin and heat sink 3, on the described heat sink 3, being formed with the cross section is the groove 5 of circular arc, and coil pipe 1 is arranged in the described groove 5, contacts with heat sink 3 maintenance faces.Owing to be provided with groove 5 with placing coil pipe 1 place on the heat sink 3, increased the contact area of coil pipe 1 with heat sink 3.Because groove 5 closely contacts with coil pipe 1 bound fraction, basically there are not the coil pipe 1 and heat sink 3 temperature difference between coil pipe 1 and the heat sink 3, but increased the heat transfer temperature difference of coil pipe 1 with air, reduced the thermograde of coil pipe 1, thermal conduction resistance reduces, the heat exchange amount is increased, and coefficient of refrigerating performance increases, and energy consumption reduces.Groove 5 the same heat exchange area that increases heat sink 3 is set, improved the heat exchange amount.
Fig. 4 is the heat sink partial sectional view of evaporator for refrigerator of the present utility model.The cross section circular arc arc length of groove described in the present embodiment 5 is more than 1/5 below 1/2 of coil pipe 1 cross circular section girth, and the internal diameter of described groove 5 is consistent with the external diameter of described coil pipe 1.So, contact closely between coil pipe 1 and the heat sink 3, thereby make that thermal resistance reduces between coil pipe 1 and the heat sink 3, increased interior fluid of coil pipe 1 and the heat exchange efficiency between the air.The cross section circular arc arc length of groove 5 is more than 1/5 below 1/2 of coil pipe 1 cross circular section girth, surpasses half of coil pipe 1 cross circular section girth, is convenient to install.Except that this embodiment, the length of the shape of the cross section of groove 5 and cross section circular arc can change.The shape of the cross section of groove 5 is according to the shape setting of coil pipe 1 cross section.Groove 5 as shown in FIG., also can be set to cross section bottom pattern jaggy, perhaps cross section is that jagged and cross section is the smooth alternate pattern of camber line, increase the contact area of groove 5 and coil pipe 1 simultaneously, under the situation of the contact area that does not change heat sink 3 and coil pipe 1, reduced the actual use amount of heat sink 3, saved manufacturing cost, as long as satisfy half of girth that the cross section circular arc of groove 5 is no more than the cross circular section of coil pipe 1, can be closely linked by the mode and the groove 5 of pressing to guarantee coil pipe 1.In the present embodiment by on heat sink 3, setting up groove 5, groove 5 has also played the effect of reinforcement, the rigidity that has improved heat sink 3 makes between coil pipe 1 and the heat sink 3 more firm, does not have loosening phenomenon and takes place, and has increased the support of coil pipe 1 and fixing ability; On the other hand, on heat sink 3, set up groove 5, under the prerequisite of refrigerator constancy of volume, increased the area of heat sink 3, thereby increased the area of dissipation of heat sink 3, reached better radiating effect.
On the heat sink 3 shown in Figure 3, the regulation zone of the part beyond the described groove 5 also is formed with shutter 4, has strengthened the thermal agitation and the air flow property of air, has increased heat exchange efficiency, has solved the little problem of the coefficient of heat transfer that exists in the prior art.
Fin 2 on the heat sink 3, groove 5, shutter 4 all forms by punch process.Production process is simple, has reduced production cost.Coil pipe 1 is an aluminum pipe, and heat sink 3 is the cotton ginning aluminium sheet.Adopt aluminum pipe and cotton ginning aluminium sheet, strength of materials height, and recyclable utilization again.In the heat exchange efficiency that guarantees evaporator for refrigerator, reduce material cost.The decorative pattern that the plane aluminium sheet rolls rule can not cause stronger reflective, and can increase visual aesthetic property.It is merely the limited problem of enabling capabilities that cotton ginning aluminium sheet and fin 2 can not solve available technology adopting cotton ginning aluminium sheet, but on the cotton ginning aluminium sheet, set up groove 5, most of weight of coil pipe 1 is transferred in the groove 5, the effect of fin 2 transfers fixation to by support and fixation, has alleviated the pressure of fin 2 greatly.Even use the long period, fin 2 is not yielding yet.If because the external force effect causes 2 of wings to deform, but, also be not easy the phenomenon that coil pipe 1 becomes flexible takes place, well solved the limited problem of cotton ginning aluminium sheet enabling capabilities because coil pipe 1 is located in the groove 5 and with groove 5 and is contacted closely.Evaporator for refrigerator of the present utility model is a plate-type evaporator, is used to be provided with in the refrigerating chamber the lower position as drawer except that can be used as refrigerating evaporator, also can be used for other and need carry out thermoregulator position.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
