CN201218642Y - A direct cooling refrigerator - Google Patents

Abstract

The utility model provides a direct cooling refrigerator comprising a liner. An evaporating pipe with one end connected with an evaporator and the other end connected with a return air pipe is arranged around the opening end of the liner; the outer surface of the liner can be provided with an evaporating pipe, and the top part or/and the left side and the right side of the liner can be provided with one or more evaporating pipes; and the evaporating pipes are fixed on the liner by an aluminum foil along the arrangement direction of the evaporating pipes. Through the continuous circulation of refrigerant in the evaporating pipes and the heat transmission of the liner, the direct cooling refrigerator can be compensated for a certain refrigerating capacity to balance the temperature, prevent the outside heat from entering the direct cooling refrigerator and improve the overall performance of the direct cooling refrigerator.

Description

A kind of Direct cold refrigerator

Technical field

The utility model relates to a kind of refrigerator, a kind of especially Direct cold refrigerator.

Background technology

External heat mainly contains two aspects to the influence of refrigerator storage temperature, is the heat transfer by body structure on the one hand, is the intrusion by imprecision slits such as gaskets on the other hand; Because frequent switch refrigerator doors in the cold draining of door envelope and the use, cold air and extraneous hot-air exchange heat near the door envelope in the refrigerator are bigger, make and seal the temperature of side than inboard temperature height near door, cold skewness weighing apparatus in the case, influenced the refrigeration of refrigerator, and because cold air is bigger than the density of hot-air, cold air is flowed to the little place of density by the density general goal, so the inboard cold air of case constantly to the supply of door envelope side, causes the loss of cold; Mainly be the tightness of reinforced door strip of paper used for sealing in the measure of taking aspect the reinforced door strip of paper used for sealing leakage thermal control at present, gasket tightness influence factor is a lot, whether the assembly building between the suction of magnetic stripe, casing and door body is out of shape apart from, casing and door foaming etc., it is more that it relates to the factor process aspect, effect is not too obvious aspect control, and the thermal loss of switch door can't be controlled with the tightness of door envelope in the use.

The utility model content

The utility model is at the deficiency in the middle of the prior art, and providing a kind of can carry out the cold compensation to refrigerator inside, makes refrigerator inside reach the Direct cold refrigerator of temperature balance.

To achieve these goals, the utility model provides a kind of Direct cold refrigerator, comprise the case courage, be provided with the evaporation tube that an end is connected with evaporimeter, the other end is connected with muffler around the openend of case courage, evaporation tube is arranged on case courage outer surface, can be at top or the right and left of case courage, can also the top, the right and left all is provided with one or more evaporation tube; Evaporation tube two tube pitch are less than or equal to 40mm, are fixed on the case courage along described evaporation tube trend with aluminium foil; By adopting technical scheme provided by the utility model, heat transfer by continuous circulation of refrigerant in the evaporation tube and case courage, the an amount of interior certain cold of case of giving compensates, balanced the temperature inside the box, make refrigerator reach balance near door envelope side temperature and inboard temperature, promptly the atmospheric density at two places is identical, and the outside supply of cold air will significantly reduce so; The density of cold air is big simultaneously can effectively stop the intrusion of external heat because the gravity effect will inevitably be sunk, and improves the overall performance of refrigerator.

The specific embodiment

Below in conjunction with the drawings and the specific embodiments the utility model is further described.

Different with the structure of conventional refrigerator except the evaporation tube that is fixed on the inner bag, the structure of the conventional refrigerator among other structures of the present utility model and Fig. 1 is identical, therefore to the incomplete structure explanation of part same as the prior art.

Extremely shown in Figure 5 as Fig. 2, add row's evaporation tube 5 near case courage opening direction at case courage 4 tops earlier as far as possible, two evaporation tubes, 5 spacings are less than or equal to 40mm, evaporation tube 5 one ends connect evaporimeter, because of the structure of evaporimeter same as the prior art, so it is not shown, the other end is connected with muffler with reservoir, because of the structure of muffler and reservoir same as the prior art, so not shown, be fixed with aluminium foil 6 again, the width of aluminium foil 6 is at least 60mm, engage to want tight between aluminium foil 6 and the case courage 4, in case advance bubble during foaming, influence is conducted heat.Refrigerant constantly circulates, the flow through evaporation tube 5 at case courage top, conduct heat by case courage 4, cold air sinks, and door envelope 2 is between casing 1 and the door body 3, at door envelope 2 and casing 1 joint, form one side layer of cold gas endlessly by cold air, effectively isolated invasion of outside heat and leaking outside of internal heat make in the refrigerator everywhere that temperature reaches balance, have improved the overall performance of refrigeration and refrigerator.

Extremely shown in Figure 7 as Fig. 4, be another embodiment of the present utility model, left side, top, right side along case courage 4 close opening parts are provided with row's evaporation tube 5 around opening, evaporation tube 5 one ends connect evaporimeter, because of the structure of evaporimeter same as the prior art, so it is not shown, the other end is connected with muffler with fluid reservoir, because of the structure of muffler same as the prior art, so not shown, be fixed with aluminium foil 6 again, the width of aluminium foil 6 is at least 60mm, engage to want tight between aluminium foil 6 and the case courage 4, in case advance bubble during foaming, influence is conducted heat.Conduct heat by the continuous circulation and the case courage of managing interior refrigerant, give cold compensation certain in the case in right amount, balanced the temperature inside the box, the overall performance of raising refrigerator.
