Abstract
The utility model discloses a step-shaped asymmetrical flat tube for a heat exchanger channel. The step-shaped asymmetrical flat tube comprises a flat body structure; a hollow long circular tube-shaped part is formed in the body structure; a plurality of convex edges are uniformly arranged on the upper surface of the body structure, have the same size, and are triangular; the upper part of one side edge of the body structure is provided with a groove; the part of the body structure, which is outside the groove, is provided with an inclined surface; a part of the lower part of the body structure, which is outside the inclined surface, is provided with a convex strip; and the convex strip has the same size as the groove, so that the convex strip of one body structure can be inserted into the groove of the other body structure to ensure that the two body structures are connected. The step-shaped asymmetrical flat tube for the heat exchanger channel can fulfill the aim of mutual fixing and connection, so that the problems that when the body structure is fixed, the connection structures such as a thread hole and the like are needed to be designed additionally, and thermal stress is produced under the condition that the body structure is not heated uniformly can be solved, and the service life of the whole body structure is prolonged.
Description
Technical field
The utility model relates to a kind of heat exchanger passages pipeline.
Background technology
The heat exchanger channels of existing heat exchanger, linking each other need to adopt auxiliary part to be fixed, such as screw etc.So just must offer screwed hole in corresponding connection, fixed position, owing to the cold and hot distribution problem of heat exchanger, easily produce the problem of structure thermal stress.
The utility model content
The purpose of this utility model is to overcome the problem of above-mentioned prior art, provides a kind of heat exchanger passages with stepped asymmetric flat tube.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of heat exchanger passages is with stepped asymmetric flat tube, the body construction that comprises flat, be made as the Long Circle tubulose of hollow in the inside of body construction, upper surface at body construction is provided with several equally distributed fins, each fin size is identical and be triangle, top at a side of body construction is provided with groove, body construction in the outside of groove is provided with the inclined-plane, the bottom of the body construction outside the inclined-plane is provided with raised line, described raised line is identical with described groove size, mutually embeds connection so that the groove of two body constructions is connected with raised line.
Heat exchanger passages described in the utility model is with stepped asymmetric flat tube, groove by a body construction and raised line and the groove of raised line and another body construction are in mating connection, can play the purpose that is mutually permanently connected, so just avoided in the fixed body structure, need the extra syndetons such as design screwed hole, avoided body construction in the situation that the problem of the uneven thermal stress that produces of being heated prolongs the service life of whole body construction.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is heat exchanger passages described in the utility model with the structure chart of stepped asymmetric flat tube.
The specific embodiment
As shown in Figure 1, the described heat exchanger passages of the utility model embodiment is with stepped asymmetric flat tube, the body construction 1 that comprises flat, be made as the Long Circle tubulose 2 of hollow in the inside of body construction 1, upper surface at body construction 1 is provided with several equally distributed fins 3, each fin 3 sizes are identical and be triangle, top at a side of body construction 1 is provided with groove 4, body construction 1 in the outside of groove 4 is provided with inclined-plane 5, the bottom of the body construction 1 in 5 outsides is provided with raised line 6 on the inclined-plane, described raised line 6 is identical with described groove 4 sizes, can mutually embed connection so that the groove 4 of two body constructions is connected with raised line.
Heat exchanger passages described in the utility model is with stepped asymmetric flat tube, groove by a body construction and raised line and the groove of raised line and another body construction are in mating connection, can play the purpose that is mutually permanently connected, so just avoided in the fixed body structure, need the extra syndetons such as design screwed hole, avoided body construction in the situation that the problem of the uneven thermal stress that produces of being heated prolongs the service life of whole body construction.
