Abstract
Disclosed is an electro thermal evaporator for realizing cold composition defrosting, which comprises an aluminum alloy flap tube, electric heating wires and a water collection disc, each of the flap tube is provided with a groove for mounting the electric heating wires and the water collection disc.
Description
Technical field
The present invention relates to a kind of device of using the electrothermal principle automatic defrosting, it is installed in the freezer refrigerating equipment on the energy-saving aluminium alloy fin tube evaporimeter, make freezer with fin tube evaporation apparatus power backup hot automatic defrosting, safe and reliable function, this evaporimeter comprise a fin tube evaporimeter and solid in deciding fin tube evaporimeter groove heating wire and below the plastics drip tray, water after the defrost flows into water-collecting tray through water receiving tank, flows out outside the storehouse at last.
Background technology
Evaporimeter mainly contains air-cooler and two kinds of forms of cold type pipe in the freezer at present.
The traditional cold cooling grid, because he has than the more advantage of air-cooler, and as freezer air humidity height, the food drying loss is few, the food chromaticness changes little in the freezer use, the interior temperature stabilizations of freezer etc. are so be widely used.
The form of traditional cold cooling grid defrost has takes out the article in the freezer space, opens cold-storage door, natural intensification defrost or increase the form of thermal source in the space; Also having the machinery defrosting or knocking vibrations makes frost separate with the evaporimeter comb; Have is exactly to adopt heat pump that evaporator temperature is raise in the Ammonia Refrigerating Equipment to cause the form of white melting layer again.Three above forms respectively have drawback, to all take out article in the storehouse when opening the cold-storage door defrost, machinery defrosting damages comb easily and refrigeration system is broken down and defrosts not thoroughly, and Defrost is subjected to the restriction and the job insecurity of refrigeration system and environment temperature.
Summary of the invention
The present invention uses the device of electrothermal principle automatic defrosting and realizes, this device can solve the weak point of above-mentioned three kinds of forms, the article in the freezer space are not taken out in the time of reaching the defrost of cold type pipe evaporator, without mechanical means defrosting or knock vibrations frost is separated with cooling grid, need not be subjected to the heat-pump-type defrost of refrigeration system and environment temperature restriction and cause job insecurity.
The present invention uses the device of electrothermal principle automatic defrosting, it is to have to specialize in by design on the fin of the fin tube of the wing of aluminium alloy pipe evaporator the Baltimore groove that heating wire is used is installed, heating wire is installed in the groove, the heat that produces during the heating wire energising, the fin tube evaporator temperature is raise, automatically melt attached to the frost on the fin tube evaporimeter when surpassing 0 ℃ and come off, the below grafting U plastic drip tray of every fin tube, one end of every group of evaporimeter is installed a water-collecting tray, water after the defrost passes through the penstock flow of water-collecting tray outside the storehouse, thereby reaches the defrost purpose.
Description of drawings
The fin tube of the charged thermalization frost of Fig. 1 device;
Fig. 2 the wing of aluminium alloy pipe evaporator.
The specific embodiment
Be described in further detail below in conjunction with accompanying drawing and embodiments of the present invention:
Shown in Figure 1 by dual-cavity fin tube 1, heating wire 2, U plastic drip tray 3 is formed.Dual-cavity fin tube 1 usefulness aluminium alloy one die cast; U plastic drip tray 3 is used the plastics extrusion modling.U plastic drip tray central opening is plugged on the fin of the wing of aluminium alloy pipe, and heating wire is installed in the dual-cavity of fin sight.Fig. 2 is arranged in parallel by the multi-disc fin tube, and to be combined into cold type be the aluminium alloy evaporimeter, the fin of fin tube and horizontal direction form 90 degree angles, all there is Baltimore groove every fin tube both sides, heating wire is installed in the Baltimore groove, and U plastic drip tray is installed all on the every fin tube, one end of every group of fin tube evaporimeter is equipped with water-collecting tray, and water-collecting tray one end is equipped with aqueduct, and the water after the defrost flows out outside the storehouse through this device.
Claims (3)
1. electricity-heated defrosting evaporator is made up of the wing of aluminium alloy pipe and heating wire and drip tray, and its structure is, every fin tube is provided with the Baltimore groove that heating wire can be installed and thereon the U type drip tray of pegging graft.
2. electricity-heated defrosting evaporator according to claim 1, it is characterized in that, fin and the pipe and the double concave groove one die cast of pipe both sides, heating wire is installed in the Baltimore groove of every fin tube, the fin below is equipped with U type drip tray, and drip tray is by an extrusion modling of plastics.
3, electricity-heated defrosting evaporator according to claim 1 is characterized in that, screw thread is arranged in the pipe, there is fin the pipe both sides, the multi-disc fin tube is arranged in parallel and is concatenated into cold type, and the fin of fin tube becomes 90 ℃ of angles with level, flows out outside the storehouse through this device through the water behind the electricity-heated defrosting.
