Description
Technical field
This utility model belongs to technical field of refrigerating devices, is specifically related to a kind of water defrosting refrigeration fan.
Background technology
In cold storage refrigerating system, when vaporizer (refrigeration fan) surface temperature is lower than 0 DEG C, vaporizer arises that frost, and the heat exchange property of vaporizer and air wide pre. drop can be produced large effect by being formed of frost. For the heat exchange property of vaporizer, the influence of frost is mainly reflected in several aspect: 1, the thermal conductivity several orders of magnitude less of the thermal conductivity of evaporator metal material of frost, and frost will increase thermal resistance in evaporator surface deposition; 2, after evaporimeter frosting, inner air runner reduced cross-sectional area, resistance increases so that flow reduces; 3, the frosting initial stage, the white grain of interruption makes heat exchange surface become coarse, and heat exchange property makes moderate progress, but after frost particle shape becomes frost layer, will affect heat transfer effect.
Water defrosting method is widely adopted as the conventional Defrost mode of one; In existing freezer water defrosting structure, it is that spray equipment is set in the inside of evaporation fan, spray equipment is connected with water tank by water pump, when needs defrost, open water pump and feed the water (can be saline) with certain pressure to spray equipment from water tank, the refrigerator pipes of vaporizer is carried out water spray defrosting, and the water after spray discharges freezer from discharge outlet; But it finds in using, and owing to the coolant-temperature gage of shower water is relatively low, causes that its defrosting effect is poor; And, after defrosting completes, the water having residual is stayed in vaporizer, and the moisture content of residual is easy to freeze.
Utility model content
The purpose of this utility model is in that to overcome the deficiencies in the prior art, it is provided that a kind of water defrosting refrigeration fan.
This utility model is achieved through the following technical solutions:
A kind of water defrosting refrigeration fan, including a casing, the one side of casing is provided with two fans for taking a breath, the side of casing is provided with kind of refrigeration cycle entrance, the opposite side of casing is provided with kind of refrigeration cycle outlet, kind of refrigeration cycle entrance is connected by being arranged on the snakelike refrigeration copper tube of box house with kind of refrigeration cycle outlet, and described refrigeration copper tube vertically bends setting; At the shower nozzle that is internally provided with of casing, the side of casing is provided with defrosting water water inlet, and water inlet is connected with shower nozzle by pipeline; The bottom surface of casing is provided with discharge outlet, and the bottom surface of casing is the ramp structure tilted to discharge outlet; Bottom surface outer wall at casing is fixedly installed a hot plate.
In technique scheme, the embedded heater strip that is provided with of hot plate, the bottom surface of described hot plate and casing fits tightly.
In technique scheme, water inlet is connected with water tank by pipeline, and is provided with electrically-controlled valve and water pump on the pipeline between water tank and water inlet.
Advantage of the present utility model and having the beneficial effect that
When carrying out defrosting, feeding water to water inlet, water enters into box house and carries out spray defrosting to refrigeration copper tube equably by shower nozzle, and the water of drippage is discharged from discharge outlet, by hot plate, the bottom surface of casing is heated, it is possible to effectively prevent the hydrops of tank floor from freezing simultaneously; The temperature in casing can also be improved simultaneously, be favorably improved defrosting speed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
Wherein: 1 is casing, and 1-1 is kind of refrigeration cycle entrance, and 1-2 is refrigeration copper tube, 1-3 is kind of refrigeration cycle outlet, and 1-4 is water inlet, and 1-5 is shower nozzle, and 1-6 is discharge outlet, and 1-7 is hot plate, and 1-8 is fan.
Detailed description of the invention
The technical solution of the utility model is further illustrated below in conjunction with specific embodiment.
Referring to accompanying drawing 1 and accompanying drawing 2, a kind of water defrosting refrigeration fan involved by this utility model, including a casing 1, the one side of casing is provided with two fan 1-8 for taking a breath, the side of casing is provided with kind of refrigeration cycle entrance 1-1, the opposite side of casing is provided with kind of refrigeration cycle outlet 1-3, kind of refrigeration cycle entrance 1-1 exports 1-3 with kind of refrigeration cycle and connects by being arranged on the snakelike refrigeration copper tube 1-2 of box house, described refrigeration copper tube 1-2 vertically bends setting, when contributing to water spray defrosting, water liquid is to dirty, thus speeding defrosting process, being internally provided with multiple shower nozzle 1-5 at casing, the side of casing is provided with defrosting water water inlet 1-4, and water inlet is connected with shower nozzle 1-5 by pipeline, the bottom surface of casing is provided with discharge outlet 1-6, and the bottom surface of casing is the ramp structure tilted to discharge outlet, so that shower water can rapidly flow toward discharge outlet, it is to avoid hydrops, bottom surface outer wall at casing is fixedly installed a hot plate 1-7, hot plate 1-7 is embedded is provided with heater strip, the bottom surface of described hot plate 1-7 and casing fits tightly, when carrying out defrosting, (water inlet is connected with water tank by pipeline to feed water to water inlet, and the pipeline between water tank and water inlet is provided with electrically-controlled valve and water pump, open electrically-controlled valve and water pump, press water is fed) to water inlet, water enters into box house and carries out spray defrosting to refrigeration copper tube equably by shower nozzle 1-5, the water of drippage is discharged from discharge outlet 1-6, by hot plate 1-7, the bottom surface of casing is heated simultaneously, the hydrops that can effectively prevent tank floor freezes, the temperature in casing can also be improved simultaneously, it is favorably improved defrosting speed.
Above this utility model has been done exemplary description; should be noted that; when without departing from core of the present utility model, any simple deformation, amendment or other those skilled in the art can not spend the equivalent replacement of creative work to each fall within protection domain of the present utility model.
