It should be apparent that the described embodiments are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

With the continuous improvement of the living standard of the materials of people, the food which needs to be preserved or frozen in daily life of people is increased, the traditional refrigerator can not meet the use requirement of users, so the refrigerators in the current market are developed in the direction of large scale. Refrigerator manufacturers on the market at present, in order to save the design and development cost of large-scale refrigerators, the design of a refrigeration system of a large-scale refrigerator is simply enlarged corresponding to the size of the refrigerator, particularly to an evaporator, the evaporator of the traditional small-scale refrigerator is formed by connecting multiple rows of evaporation tubes in series and is designed in a single flow path, the length of the evaporation tubes of the evaporator of the current large-scale refrigerator is only prolonged on the basis of the evaporator of the traditional small-scale refrigerator, so that the evaporator can cover the whole storage chamber, due to the extremely large extension of the tubes of the evaporator, the flow path of a refrigerant flowing from an inlet of the evaporator to an outlet of the evaporator is prolonged, the flow resistance of the refrigerant is increased, the power consumption of a compressor driving the refrigerant to flow is greatly increased, the power consumption of the refrigerator is increased, and the electricity consumption cost of a user is increased.

In order to reduce the power consumption of the compressor and save the electricity cost of a user, the embodiment of the application provides a novel evaporator assembly.

In particular, the evaporator assembly can be applied to large-scale refrigeration equipment such as a refrigerator, an ice chest, an air conditioner and the like, and the evaporator assembly is described in detail by taking the refrigerator as an example.

Referring to fig. 1, in the present embodiment, an evaporator assembly 100 includes an evaporator 10; the evaporator 10 includes at least two evaporation coils 11, each evaporation coil 11 includes a refrigerant channel and an inlet end 11a and an outlet end 11b communicated with the refrigerant channel, the inlet ends 11a of all the evaporation coils 11 are located on the same side and are arranged in parallel, and the outlet ends 11b of all the evaporation coils 11 are located on the same side and are arranged in parallel.

Wherein, at least two evaporation coils 11 are arranged side by side; specifically, the evaporator assembly 100 is configured to be installed in an evaporation chamber of a refrigerator, and at least two evaporation coils 11 are arranged side by side along a depth (thickness) direction of the evaporation chamber.

It can be understood that, when the evaporator assembly 100 is applied to a refrigerator, the refrigerant flows into the refrigerant channels from the inlet ends 11a respectively, that is, the refrigerant enters the evaporator 10 and is divided into multiple flow paths to be evaporated and vaporized in the evaporator 10, and in the evaporator in which multiple rows of evaporation tubes are connected in series end to end, the refrigerant needs to walk through one row of evaporation tubes after entering from the evaporator inlet, and can enter another adjacent row of evaporation tubes until the refrigerant can flow out from the evaporator outlet after walking through the whole course, in this application, the refrigerant enters from the inlet end 11a of the evaporator 10 and then flows in multiple paths simultaneously in the evaporation tubes 11 until flowing out from the outlet end 11b, so that the distance from the evaporator 10 inlet to the evaporator 10 outlet is shortened, and the flow distance from the inlet end 11a to the outlet end 11b of the refrigerant is reduced, the friction with the inner wall of the evaporation tubes 11 is reduced, and the flow resistance from the inlet end 11a to the outlet end 11b of the refrigerant is reduced, thereby reducing the power consumption of the compressor driving the flowing, and further reducing the electricity consumption of the refrigerator.

The number of the evaporating coils 11 can be two, three or more, and the number of the evaporating coils 11 in the drawings of the embodiments of the present application is set by taking two as an example, but is not to be considered as a limitation of the present application. It should be noted that, when the evaporator assembly 100 is applied to a refrigerator, the number of the evaporation coils 11 should not be too large, and too many evaporation coils 11 mean that the thickness of the evaporator 10 is increased, which affects the space of the storage chamber of the refrigerator.

Specifically, taking two evaporation coils 11 as an example, the refrigerant flows in from the inlet ends 11a of the two evaporation coils 11 respectively, and flows in the refrigerant channels of the two evaporation coils 11, and compared with the evaporator in which two rows of evaporation pipes are connected in series end to end in the market, the flow distance of the refrigerant from the evaporator inlet to the evaporator outlet is shortened by half.

It can be understood that, because of the use habit of the user and the effect of external environment factors, the refrigerant has the insufficient condition of evaporation in the evaporating coil 11 inevitably, and to the refrigerant that has not evaporated vaporization yet (namely liquid refrigerant), after the liquid refrigerant got into the compressor, because its volume can not be compressed, lead to the compressor internal pressure to increase suddenly in the twinkling of an eye, hit the exhaust valve piece of compressor very easily, take place the liquid and hit the phenomenon promptly, so need set up reservoir 30 at the exit end 11b of evaporating coil 11.

Reservoir 30 is vapour and liquid separator promptly, can be with gas and liquid separation, this application embodiment is connected with connecting pipe 111 through the inlet end that sets up reservoir 30, still there is not the refrigerant that has vaporized in evaporating coil 11, then the gaseous state refrigerant of mixture passes through connecting pipe 111 with liquid refrigerant and gets into in the reservoir 30, under the separating action of reservoir 30, the gaseous state refrigerant flows through the outlet duct of reservoir 30, and get into in the compressor through refrigerant output tube 20, and liquid refrigerant persists temporarily in reservoir 30, and in the evaporation rethread refrigerant output tube 20 gets into the compressor after progressively absorbing heat.
