The condenser core or the evaporator core comprises a plurality of fins, square tubes and a plurality of flat tubes, wherein one flat tube is clamped between every two adjacent fins, and after the fins and the flat tubes are combined, two ends of the condenser core or the evaporator core are clamped and limited through the square tubes. Before the fins and the flat tubes between the two square tubes are clamped, the heights of the fins and the flat tubes are inconsistent, and the fins and the flat tubes need to be flattened.

Because of the different lengths of the fins in the condenser core and the evaporator core, the existing slapping usually utilizes a whole slapping plate to completely cover the integral structure of the core, and the slapping plate is pressed down, so that the core is slapped. Because the existing cores are large in size, the size of the flapper is also large. The bigger the size of the clapping plate is, the more easily deformed, the structural dimensional stability of the clapping plate is poor, and the phenomenon that the two ends of the fins cannot be clapped frequently occurs, or the fins at the two ends are clapped, so that the force applied to the middle of the fins by the clapping plate is large, the two ends of the core body are upwarped upwards, and the clapping is uneven.

In order to ensure that the fins can be flattened by pressing down the three plates, the fins are required to be completely covered by the three plates. In this case, the thickness of the second clapper 22 and the third clapper 32 is the same as the thickness of the first clapper 11. The dimensions of first clapper 11 should be as large as possible and the dimensions of second clapper 22 and third clapper 32 should be as small as possible.

Optionally, the horizontal central axis of the air hole 411 coincides with the horizontal central axis of the long fin 5, so as to ensure that the force of the air on the long fin 5 is not deflected during the air blowing process, and the air blowing effect on the long fin 5 is the best.

As shown in fig. 8, the gas blowing hole 411 includes a straight hole section 4111 and an inclined section 4112 connected to each other, the straight hole section 4111 being disposed in a vertical direction, the inclined section 4112 being inclined toward a direction in which the long fin 5 protrudes, and forming a predetermined angle α with respect to a horizontal direction. The straight hole section 4111 is internally provided with a threaded hole, the throttle valve is arranged in the threaded hole on the mounting block, the throttle valve is inserted into the air pipe to be connected with an external air source, and the opening degree of the throttle valve is adjusted to control the air blowing amount.

The preset angle alpha is inversely proportional to the height of the long fins 5. The preset angle alpha is determined according to the height of the fins, and the higher the height is, the smaller the preset angle alpha is. The preset angle alpha in this embodiment is in the range of 15 deg. -20 deg..

As shown in fig. 4, the structure of the air vent 411 in this embodiment is that the air vent 411 blows air to the end protruding along the long fin 5, so that in order to blow the long fin 5, the long fin 5 is thin in a natural state, and is easy to bend, and in the leveling process, a crushing phenomenon is easy to occur. The long fins 5 are blown through the air blowing holes 411, so that two adjacent flat tubes 7 are better attached to the fins, gaps are reduced, and the quality of the molded core body is ensured.

Meanwhile, the preset angle α of the inclination of the air blowing hole 411 in this embodiment is 15 °, while the long fins 5 are blown straight, all the fins are blown to one direction, and in the unclamped state, all the fins are inclined to the same direction, so that the fins are crushed or clamped in the process of flattening, and the quality of the core is further ensured.

When the device is in leveling work, as the long fins and the short fins exist in the core body, the long fins and the short fins of the core body are blown to the same side by the blowing assembly. And then the controller is used for controlling three clapping plates in the three groups of clapping assemblies to descend simultaneously, and the fins are slapped. The controller is internally provided with three groups of leveling components for continuously leveling two to three times so as to completely level the long fins 5 and the short fins 6, ensure the leveling effect and further finish the leveling operation of a core body.

The clapping plates in this embodiment are set to be the first clapping plate 11, the second clapping plate 22 and the third clapping plate 32, respectively with the cylinder output fixed connection on the fixed plate of each, each clapping plate is clapped respectively, the combined action plays the effect of clapping evenly, has solved a monoblock clapping plate structure simultaneously too big, processing difficulty, and processing procedure is complicated, the problem of poor yielding of structural stability.

In this embodiment, since the connection block 18 and the hooking block 19 are provided, the first clamping portion and the second clamping portion are mutually matched to form a hook, and then the positioning groove between the first connection plate 14 and the first L-shaped member 16 is utilized, and then the installation can be completed by locking. If the dimensions of the first clapper 11 are changed, a quick change of shape is achieved.

Because the device is divided into three clapper plates, the contact with the core body is more uniform, and the clapping core body is flat and stable. Meanwhile, due to the adoption of the three-piece clapping plate structure, the size of the first clapping plate in the middle is reduced, and the processing requirement can be reduced, so that the required flatness can be ensured.

It is to be understood that the above examples of the present invention are provided for clarity of illustration only and are not limiting of the embodiments of the present invention. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments.
