Abstract

The utility model relates to an evaporator, particularly an evaporator for an electric freezer or an electric refrigerator. The evaporator provided by the utility model is the backspin-shaped evaporator 1 made of copper pipes the outside of the evaporator is fixed with a box body 6 made of aluminum foil, the backspin-shaped evaporator 1 is fixed in an interlayer 5. The utility model has the advantages that the box body does not need to be disassembled at the of repairing the internal leakage, and the appearance of the original refrigerator or freezer can be kept; the copper evaporator is easily corroded; meanwhile, the heat-insulating effect can be improved, and the service life of the refrigerator or the freezer can be extended.

Description

Ice box or evaporator of electric refrigerator

The utility model relates to a kind of evaporimeter, especially the evaporimeter of ice box or use in refrigerator.

The evaporimeter of present commercially available ice box or refrigerator is aluminum products, and aluminium matter evaporimeter often has interior leakage accident to take place because of being subject to the corrosion of fluorine Lyons.When maintenance, must push casing aside, take out insulation material, mending-leakage or replacing refrigeration organ pipe, maintenance finishes and installs foamed plastic again additional.This method for maintaining is time-consuming, require great effort and destroyed the original moulding and the heat-insulating property of refrigerator or ice box.

The purpose of this utility model is to develop a kind of tubular evaparator that is not subject to the corrosion of fluorine Lyons, needn't push casing aside when maintenance ice box or refrigerator, does not destroy original appearance and modeling and heat-insulating property.

The utility model is achieved in that the evaporimeter of ice box or refrigerator is to curve repeatedly convoluted shape and it is fixed on the inwall of ice box or refrigerator with copper pipe.One end of Cyclotron copper pipe passes ice box and is welded on the muffler of compressor, and copper capillary tube of other end welding is welded on this capillary on the device for drying and filtering again.

Advantage of the present utility model is, because the arborescence performance, the anti-fluorine of the evaporimeter that copper pipe is made Lyons corrosive nature is better than aluminium matter goods.And be easy to processing, and eliminate original evaporimeter when in maintenance, leaking electricity refrigerator-freezer or refrigerator, change the utility model into, needn't push casing aside, do not destroy thermal insulation layer, kept the appearance and modeling of former refrigerator or ice box.

Describe embodiment of the present utility model and concrete structure in detail below in conjunction with accompanying drawing.

Embodiment one: in handling during 145 liters of horizontal chest freezers of leakage, on the close casing 7 at compressor return air pipe position, chisel the hole of 1 centimetre of a diameter, 8 millimeters copper pipes are worn muffler position to compressor from the hole, after device to be evaporated installs, this copper pipe and muffler are welded.The copper pipe that to stay in the ice box with pipe bender curls up into the three-dimensional Cyclotron evaporimeter 1 of similar square spring-like along four inwalls of ice box (removing four inwalls of last lid and bottom), welding copper capillary tube 4 in copper pipe end is welded on capillary 4 on the device for drying and filtering again.But copper pipe coiling six circles, 8 millimeters of every circle spacings are fixed on the ice box cabinet wall with aluminum foil strip 2 and self-tapping screw 3.Other refrigerator-freezer can suitably increase or reduce the number of turns and the spacing of gyrotron according to volume size.

In order to protect the solid shape evaporimeter 1 that circles round, improve evaporimeter performance and attractive in appearance for the purpose of, available thickness is 0.75 millimeter a aluminium foil, make one and be fixed on the ice box inwall, with the top of pressing the picture bar or decorateing press strip joint sealing body than each little 1 centimetre casing 6 of ice box endosome length and with self-tapping screw; With the fixing picture bar of pressing of the plastic strip that scribbles fish pearl glue.So just make the solid shape evaporimeter 1 that circles round be fixed in the interlayer 5 between aluminium foil casing 6 and the ice box casing and be protected.Three-dimensional Cyclotron evaporimeter 1 also can curl up shaping in advance, is bonded on the aluminium foil casing 6, puts in the ice box fixing again.

The copper pipe of making three-dimensional Cyclotron evaporimeter 1 can be pressed into semicircle in advance, and the one side that is copper pipe as shown in Figure 3 is the plane, and another side is semicircle, and the planar section of copper pipe contacts with the ice box internal box.Work both can account for the dischargeable capacity of ice box as far as possible less like this, was convenient to again fix.

Embodiment 2: the freezer chamber of refrigerator evaporimeter can be used structure fabrication same as described above.Refrigerating chamber does not need very low temperature, thus the copper pipe evaporimeter can be made into the plane Cyclotron, as shown in Figure 2.Aluminium foil of evaporimeter 1 fixed outside is fixed between the freezer wall and aluminium foil of this refrigerator the plane shape evaporimeter 1 that circles round.

More than described concrete structure of the present utility model in detail, hence one can see that, with the evaporimeter of copper pipe making, compare with aluminium matter evaporimeter, the corrosion in more anti-fluorine Lyons is when leaking electricity refrigerator-freezer and refrigerator in maintenance, casing be needn't push aside, original appearance and modeling and heat-insulation layer do not destroyed.Thereby reached the purpose of this utility model.In addition, interior leakage refrigerator-freezer and refrigerator through utilizing the utility model to keep in repair because of not pushing their casing aside, do not destroy original evaporimeter 9 and thermal insulation layer 8, interlayer 5 has heat insulation effect again, thereby has reduced the speed that heats of refrigerator-freezer or refrigerator after compressor shuts down.Press the refrigerator-freezer that embodiment 1 keeped in repair, when 20 ℃ of room temperatures, former refrigerator-freezer running half an hour, shut down 20 minutes; after the maintenance, turn round half an hour, shut down 60 minutes, because of the compressor start frequency reduces; and saves energy significantly increases the service life, and user and society are had good benefit.
