Abstract
The utility model relates to an air cooling refrigerator air duct for supplying air, which comprises an air duct and air outlets. The air duct is divided into a main air duct and branch air ducts. Each air outlet is arranged at the tail end of the corner of each branch air duct. The branch air ducts can be detached from the main air duct step by step, which is similar to the structure of the branch. The communication position of each branch air duct and the main air duct is provided with a flow guiding sheet of which the direction is consistent with the direction of the air flow. Each flow guiding sheet and the main air duct can form a flow guiding section of each branch air duct. Because the communication position of each branch air duct and the main air duct is provided with one flow guiding sheet of which the direction is consistent with the direction of the air flow, the variation of pipe diameter with larger resistance, such as the immediately enlarging operation or the immediately shrinking operation, etc. can be eliminated so as to reduce disturbance caused by the branch of air flow. Thus, energy loss in the process of energy conversion can be reduced; the amount of air supply can be enhanced; machine running efficiency of the refrigerator can be lowered; energy consumption of the refrigerator can be reduced. The utility model can accurately distribute the amount of air supply for a refrigerating chamber and a cold storage chamber by the matched cross sectional area of each branch air duct.
Description
Technical field
The utility model relates to the refrigerator technical field, is specifically related to reduce duct resistance, accurately distributes the wind cooling refrigerator supply air duct of air-supply for refrigerating chamber and refrigerating chamber.
Technical background
The present refrigeration modes of cold storage chamber of refrigerator mainly contains two kinds, and is air-cooled and direct-cooled.Air cooling way adopts fan air-supply, helps the uniformity of temperature of refrigerating chamber, and refrigerating speed is very fast, but the air channel design has very big influence to the energy consumption of wind cooling refrigerator, if the air channel without well-designed, is perhaps designed unreasonable, resistance is bigger, can bring the problem of the following aspects:
1. the evaporator external wind speed is slow, and convection transfer rate is little, and heat transfer temperature difference is big, causes evaporating temperature on the low side, and refrigeration system efficient is low;
2. air output is little, and the temperature of refrigerating chamber and refrigerating chamber descends slowlyer, needs the air-supply of longer time, and the compressor Homes Using TV is big;
3. refrigerating chamber is directly proportional with the product of each air port air output and import and export wind-warm syndrome with the cold of refrigerating chamber, the ratio of this cold should be corresponding with the thermic load estimation in the design process, the cold ratio that offers each chamber without well-designed air channel is unknown, relatively blindly, cold that provides and thermic load coupling are bad, and be unfavorable to temperature control.
The air-supply of refrigerator back is generally adopted in the air channel at present, and the inboard whole space of fan outlet cover plate directly sets out the air port for the position of refrigerating chamber or refrigerating chamber air-supply all as air-supply passage at needs.The cold wind that fan outlet comes out in this design is that sudden expansion is flowed, and very strong disturbance can take place; Do not have guiding device at each air outlet, must realize the transformation and the air-supply of direction by the conversion of kinetic energy-pressure-kinetic energy, the pressure loss is bigger, and fan resistance is bigger; Can't do accurate estimation to the air quantity of each air outlet in the design process, therefore unfavorable to the temperature control of refrigerator.
The utility model content
The purpose of this utility model is the shortcoming that overcomes prior art, provides a kind of and can reduce duct resistance, accurately distributes the wind cooling refrigerator supply air duct of air-supply for refrigerating chamber and refrigerating chamber.
The purpose of this utility model can realize by following technical proposal.
The utility model includes air channel and air outlet, the air channel is divided into main air duct and divides branch air duct, air outlet is arranged on the turning end of each minute branch air duct, divide branch air duct to tell with the structure that is similar to branch step by step by main air duct, each divides branch air duct to be provided with and the consistent flow deflector of wind flow direction with main air duct connection place, and flow deflector and main air duct constitute the diversion section of each minute branch air duct.
For further reducing duct resistance, the energy loss when avoiding the conversion of momentum and pressure as much as possible, the turning employing fillet flow-guiding structure of the close air outlet of above-mentioned each minute branch air duct.
The utility model compared with prior art its beneficial effect is: each divides branch air duct to be provided with and the consistent flow deflector of wind flow direction with main air duct connection place, flow deflector and main air duct constitute the diversion section of each minute branch air duct, therefore, having eliminated the bigger caliber of resistances such as sudden expansion or sudden contraction changes, the cold air that fan of refrigerator is sent flows into each minute during branch air duct in the air channel, in diversion section, realize water conservancy diversion by flow deflector, each branch's shunting is flowed level and smooth, reduced the disturbance that air flows causes, reduced the energy loss in the power conversion, improve air output, reduce the Homes Using TV of refrigerator, reduce energy consumption of refrigerator; And main air duct with each minute branch air duct area of section be directly proportional substantially with air output in each air channel; Therefore can be by the design of duct cross-section area, by the coupling of area of section of each minute branch air duct, accurately distribute refrigerating chamber, refrigerating chamber air output.
Description of drawings
Fig. 1 encloses the structural representation of fan for the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
As shown in Figure 1, the utility model includes air channel and air outlet 4, the air channel is divided into main air duct 1 and divides branch air duct 2, during use, fan of refrigerator 3 is located at main air duct 1 one ends, and the lower side circle is fan of refrigerator 3 among the figure, by upwards air-supply of main air duct 1, in first freezing air-out bifurcation, main air duct 1 is divided into three parts by two flow deflectors 5, and the left and right sides is freezing air-out diversion section.Air-out is through dividing branch air duct 2 circular-arc air-supply structures, direction is by upwards becoming level, send into refrigerating chamber through air outlet 4, divide branch air duct 2 bifurcation and main air duct 1 area of section sum before and after branch, not to change, the air velocity that is branch and main flow remains unchanged, and has avoided the energy loss in the branching process as far as possible; Air-flow in the main air duct 1 continues upwards, and the freezing air outlet of the air channel end is identical with last branch with the bifurcation approach of refrigeration air outlet, keeps flow velocity not undergo mutation, and airflow direction all adopts the arc structure water conservancy diversion when changing, reduce energy loss.
The utility model can be used for the accurate energy-conservation air-supply of various wind cooling refrigerators.
