The central axis of the fuisw rib refers to the central axis along the extending direction orientation of the fuisw rib.It can make the water conservancy diversion in this way
Muscle is more smooth to the guide effect of air-flow, avoids generating the region for generating air-flow larger resistance, ensures the air-supply wind of refrigerator 1
Amount.
Specifically, as shown in figs 1 to 6, the heat exchanger is finned heat exchanger, and the fuisw rib is with the heat exchanger
It is axis axial symmetry in the center line of the length direction for the fin for being parallel to the heat exchanger.Specifically, the symmetry axis is before and after
(as shown by the arrow, front-rear direction is not set front-rear direction direction orientation only for the purposes of statement for the application is practical
Put the restriction in direction).The fuisw rib can be made to generate the uniform water conservancy diversion effect in left and right in this way, avoid the occurrence of the heat exchanger two
The situation of crosswind amount unevenness so as to further improve the uniformity of the heat exchange of the heat exchanger, further improves the heat exchanger
Heat transfer effect.
More specifically, as shown in figs 1 to 6, the fuisw rib includes mutual axisymmetric two symmetrical limbs 111, each
The central axis of symmetrical limb 111 is the spline curve by 4 points of control.The water conservancy diversion effect for making the fuisw rib in this way is cleverer
Work is various, and different water conservancy diversion effects is realized convenient for the fuisw rib, so as to further convenient for the heat exchange effect of the raising heat exchanger
Fruit.
Further, as shown in fig. 6, the central axis of each symmetrical limb 111 is the first control point by being arranged in order
P1, the second control point P2, third control point P3 and the spline curve of the 4th control point P4 controls, the 4th control point P4 are located at place
One end that symmetrical limb 111 is connected with another symmetrical limb 111, the first control point P1 are located at the other end of symmetrical limb 111, the second control
Point P2 is deviated backward relative to the imaginary line of the first control point P1 and the 4th control point P4, and third control point P3 is with respect to the first control
The imaginary line biased forwards of point P1 and the 4th control point P4 are flowed by the air-flow of the heat exchanger from the front end of the heat exchanger
It moves to the rear end of the heat exchanger.The flexibility of the fuisw rib can be further improved in this way, so as to be convenient for described
The true form of fuisw rib is controlled.
Fig. 6 shows the refrigerator 1 according to a specific example of the invention.As shown in fig. 6, the air-flow by the heat exchanger
The rear end of the heat exchanger is flowed to from the front end of the heat exchanger, the both ends of the fuisw rib are respectively adjacent to the heat exchanger
Left back end and right rear end are set, and are set at the center on the front edge of the heat exchanger at the center of the fuisw rib.In this way
The water conservancy diversion effect of the fuisw rib can be enable to cover the entirety of the heat exchanger as possible, avoid generate water conservancy diversion less than area
Domain, so as to further improve the heat transfer effect of the heat exchanger, while the air-flow that the past side can be made to flow to the heat exchanger produces
Raw shunting to the left and to the right makes to obtain uniform water conservancy diversion effect at left and right sides of the heat exchanger, improves the heat exchanger
Exchange heat uniformity, improves the heat transfer effect of the heat exchanger.
Specifically, the fuisw rib is only against on the heat exchanger.Specifically, upper fuisw rib 110 is only against described change
On the upper surface of hot device, lower fuisw rib 210 is only against on the lower surface of the heat exchanger.More specifically, upper fuisw rib 110 stops
The upper edge of the fin of the heat exchanger is against, lower fuisw rib 210 stops the lower edge for the fin for being against the heat exchanger.In this way may be used
To improve the locating effect of upper fuisw rib 110 and lower fuisw rib 210 to the heat exchanger, so as to further improve the heat exchanger
Stability and reliability, further convenient for the assembling of the heat exchanger.
