Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
The following discloses many different embodiments or examples for implementing the subject technology described. In order to simplify the disclosure, a specific example of one or more permutations of the features is described below, but the present disclosure is not limited to the specific example, and the first feature described later in the specification may be connected to the second feature in a direct connection, or may include an embodiment forming an additional feature, and further, may include the use of one or more other intervening features to connect or combine the first feature and the second feature indirectly with each other so that the first feature and the second feature may not be directly connected.
The application discloses embodiment of plate-fin radiator core includes: a fin 1 and a harmonica tube 2.
Wherein, fin 1 includes two at least, and fin 1 is parallel arrangement in proper order, and in an example, fin 1 can be parallel arrangement in proper order from top to bottom, and the fin 1 that this application shows comprises the finned plate that is used for the radiating that a plurality of parallel arrangement or non-parallel arrangement arranged.
The gaps between the harmonica tubes 2 and the fins 1 correspond to each other one by one, for example, in an embodiment including two fins 1, only one gap is formed between each fin 1, the number of the harmonica tubes 2 is also only one, the harmonica tubes 2 are arranged between the adjacent fins 1, and the harmonica tubes 2 are directly connected with the adjacent fins 1, that is, no other interlayer structure exists between the harmonica tubes 2 and the fins 1, and in an embodiment, a brazing material layer is arranged on the surfaces of the fins 1, so that the fins 1 and the harmonica tubes 2 can be directly welded conveniently.
In the embodiment disclosed in the present application, two ends of the fin 1 are further fixed with sealing strips 3, in one example, the sealing strips 3 are provided with flux-cored wires 4, and the end sockets 6 can be conveniently welded and fixed with the fin 1 and the harmonica tube 2 through the flux-cored wires 4.
The side plate 5 is further included in the embodiment disclosed in the application, the side plate 5 is fixed to one side, away from the harmonica tube 2, of the fin 1 on the outermost layer, so that the embodiment in which the fins 1 are arranged from top to bottom is described, the fin 1 on the outermost layer is the fin 1 at the topmost end and the bottommost end, and the side plate 5 is fixedly connected with the fin 1 on the outermost layer.
