Description
Technical field
The utility model relates to refrigerator field, particularly relates to a kind of refrigerator with combined type refrigerating evaporator.
Background technology
In prior art, the refrigerating evaporator used in ordinary straight cold refrigerator is generally external freezing evaporator of fiber pipe.Be arranged on the inner surface of refrigerator freezing inner bag by refrigerating evaporator, be positioned at the cavity volume of refrigerating chamber placing articles.Adopt the advantage of the wire-tube evaporator of this mounting means to be: 1, refrigeration is fast: directly and air carry out heat exchange, cold-producing medium is little at pipeline internal resistance, velocity of liquid assets is fast; 2, bearing capacity is strong: the weighted design of every block wire-tube evaporator all reaches 50kg; 3, corrosion-resistant: double-deck copper facing plastic-blasting Bundy tube, surface is through the workmanship of spraying plastics process of 0.2 millimeter, and prevent air oxidation, corrosion resistance is strong.
But, spatial volume that external evaporimeter takies that what current national standard required should deduct when refrigerator dischargeable capacity is measured, therefore the dischargeable capacity of freezing chamber gallbladder intracavity is frozen evaporimeter and takies sub-fraction, and refrigerating chamber dischargeable capacity is diminished; Diminishing of dischargeable capacity makes the nominal volume of refrigerator follow decline, and when calculating refrigerator energy efficiency market and grade limit value, numerical value is less than normal, and the space simultaneously leaving refrigerating evaporator installation for fixing also seems very compact.
And the external setting of refrigerating evaporator and the direct heat exchange of air easily cause evaporator surface frosting, and along with the increase of service time, frost can be tied thicker and thicker, so that affect refrigeration.Existing direct cooling refrigerator refrigerating chamber because of between indoor air be free convection, cold air sinks, hot-air rises, and upper and lower temperature difference is large, and uniformity is bad.
Compressor due to refrigerator is arranged on the freezing inner bag lower outer in refrigerating chamber, very near apart from the bottom surface of freezing inner bag, during work, owing to being only all provided with refrigerating evaporator in the upside of freezing inner bag and the left and right sides, in the downside of freezing inner bag, refrigerating evaporator is not set.During work, the upside of freezing inner bag and the refrigerating evaporator refrigeration of the left and right sides make the cold air on freezing inner bag top sink, and then the high temperature air of freezing inner bag bottom is substituted by the cold air on top.Because this refrigeration modes to make the cools air of freezing inner bag bottom by cross-ventilation, so the cooling rate in freezing inner bag is slow, the non-uniform temperature in freezing inner bag, the Temperature Difference Ratio of top to bottom, left and right, front and rear is larger.
For above problem, need badly and want a kind of new refrigerator, be frozen evaporimeter with the dischargeable capacity solving the freezing chamber gallbladder intracavity existed in prior art and take sub-fraction, refrigerating chamber dischargeable capacity is diminished, and cooling rate during refrigeration in freezing inner bag is slow, the problem that the temperature difference of the top to bottom, left and right, front and rear in freezing inner bag is larger.
