Abstract
The present invention provides an n-type three-surface nesting type evaporator and a manufacture method thereof fore an electric refrigerator with two doors. The evaporator comprises an evaporator body and a coil pipe in the prior art, wherein the evaporator body uses an n-type three-surface type. Compared with the prior art, an aluminium sheet can be saved, and the cost can be reduced. Difficult problems that sewage is accumulated on the bottom and the dirt smells rotten are overcome. Edge sealing is carried out on the evaporator by using plastic decorating strips, which increases the degree of tightness and beautiful degree. When manufactured, epoxy adhesives added with metal powders are coated on the coil pipe 3, the coil pipe 3 is bonded on the unfolded evaporator body and is bent after the adhesives are solidified to manufacture the n-type three-surface nesting type evaporator of which the internal dimension is matched with that of the evaporator to be repaired.
Description
The present invention relates to a kind of preparation method of the sleeve type evaporimeter that double-door refrigerator uses and sleeve type evaporimeter of making of the method repaired.
Repair the double-door refrigerator evaporimeter at present and all adopt a kind of new method, promptly adopt embedded evaporator.Chinese patent 89212450.4(Fig. 1) and application number be 90213014.5(Fig. 2) the utility model patent specification this embedded evaporator is all disclosed.Above-mentioned embedded evaporator mainly is made up of evaporator body 2, press strip 1 and coil pipe 3.During making, the coil pipe 3 of bending good shape is placed on the evaporator body 2 of expansion.On press strip 1, coat bonding agent then, again press strip 1 is bonded on the evaporator body 2.Like this, by just coil pipe 3 being fixed on the evaporator body 2 with the bonding press strip 1 of evaporator body 2.Evaporator body 2 bendings that at last cementation had coil pipe 3.The overall size of the evaporator body of making 2 matches with evaporator of electric refrigerator inside dimension to be repaired.Adopt press strip 1 that the embedded evaporator that coil pipe 3 is fixed on the evaporator body 2 is had two shortcomings, the one, coil pipe 3 and evaporator body 2 are not all closely to be close together, exist the gap but have between the contact-making surface of most of coil pipe 3 and evaporator body 2, the existence in this gap has reduced the refrigeration of refrigerator.When the refrigerator of repairing has just been brought into use, owing to have the gap between the contact-making surface of most of coil pipe 3 and evaporator body 2, the conduction between most of coil pipe 3 and the evaporator body 2 will be undertaken by air, thereby reduce the refrigeration of refrigerator.After using a period of time, just be covered with ice in the gap between coil pipe 3 and the evaporator body 2, the conduction between coil pipe 3 and the evaporator body 2 will be undertaken by this layer ice, and this also makes the refrigeration of refrigerator reduce.In addition, the horn mouth on the evaporator body 2 be directly on evaporator body 3 bending form, make cumbersome, also not too attractive in appearance after being contained on the refrigerator.The 2nd, adopt the four sides all to be furnished with the cartridge type of bend pipe.Behind the embeddeding refrigerator, have sizable gap between bottom and the freezer compartment floor.When defrosting, sewage infiltrates the bottom can't be removed, and the time one is of a specified duration, just volatilizes strong stink, and refrigerator can't be used.
The objective of the invention is the manufacture craft of existing embedded evaporator is improved, eliminate the gap that exists between coil pipe 3 and the evaporator body 2, improve the refrigeration of refrigerator, be convenient to remove bottom sewage.
Technical solution of the present invention is such, and it comprises building block evaporator body 2 of the prior art and coil pipe 3, cancellation press strip 1.During making, fix coil pipe 3, but adopt the bonding agent that adds the certain proportion metal dust coil pipe 3 directly to be cemented on the evaporator body 2 of expansion, eliminate the gap between coil pipe 3 and the evaporator body 2 without press strip 1.Owing to the thermal conductivity ratio air and the ice of the bonding agent that is added with metal dust are all much higher, be exactly the part that has of coil pipe 3 with evaporator body 2 between be not directly to contact, but be full of the bonding agent that is added with metal dust in the gap between them, refrigeration is than fixing much better of available technology adopting press strip 1.Refrigeration compared with prior art can improve 20%.In addition, cancel the horn mouth edge sealing on original embedded evaporator, adopt decorative plastic bar edge sealing to increase its tightness and attractive in appearance.Evaporator body 2 adopts three formulas of " " type to compare with four sides of the prior art formula can save aluminium sheet, reduces cost.Contamination water is not convenient to clean.Overcome owing to the volatilize shortcoming of stink of contamination water.Now the present invention is made detailed description:
Accompanying drawing 1,2 is an embedded evaporator of the prior art.
Accompanying drawing 3 is three sleeve type evaporimeters of " " provided by the invention type.
Accompanying drawing 4 is decorative strip structure figure.
The evaporator body 2 of three suits of " " provided by the invention type (promptly embedded) evaporimeter adopts three formulas of " " type, and material adopts Figured aluminium plate.The cross section of coil pipe 3 is semicircle.The edge sealing of evaporator body 2 does not adopt the horn mouth form, but adopts decorative plastic bar edge sealing 4, to increase its sealing property and attractive in appearance.During making, the epoxy resin adhesive that is added with 20～25% metal dusts is coated on the composition surface of coil pipe 3 and evaporator body 2, the cross section be semicircular coil pipe 3 the plane for the composition surface of evaporator body 2, again coil pipe 3 is cemented on the evaporator body 2 of expansion, treat to carry out bending after bonding agent solidifies, make and three sleeve type evaporimeters of " " type that evaporimeter inside dimension to be repaired matches.Last bending technology is the same with bending technology of the prior art.4 injection mouldings on plastic injection equipment of decorative plastic bar edge sealing are adopted three or four and are assembled on the evaporator body 2.
Claims (3)
1, a kind of preparation method of sleeve type evaporimeter, it is characterized in that the epoxy resin adhesive that will be added with 20～25% metal dusts is coated on the composition surface of bending good coil pipe (3) and evaporator body (2), again coil pipe (3) is cemented on the evaporator body (2) of expansion, treat to carry out bending after bonding agent solidifies, make and sleeve type evaporimeter that evaporimeter inside dimension to be repaired matches.
2, the preparation method of sleeve type evaporimeter as claimed in claim 1, the granularity that it is characterized in that metal dust is between 160～240 orders.
3, the sleeve type evaporimeter manufactured of preparation method as claimed in claim 1 or 2, three formula evaporator bodies of " " type that it comprises and evaporimeter inside dimension to be repaired matches (2) and coil pipe (3), it is characterized in that having between the composition surface of evaporator body (2) and coil pipe (3) one deck can improve the epoxy resin adhesive that contains metal dust of pyroconductivity, go up at evaporator body (2) and adopt decorative plastic bar edge sealing (4).
