According to the embodiment of the invention, the first tube plate 16 is arranged on the evaporator 12, and the protrusion 1511 is arranged on the air duct framework 151 of the air duct, so that the first tube plate 16 and the protrusion 1511 are directly detachably connected, the assembly of the evaporator 12 and the air duct by using the tube plate connecting plate 10 is avoided, the assembly process of the assembly structure of the evaporator 12 is simplified, and the production cost is reduced.

In some alternative embodiments, the first tube sheet 16 is disposed at the side of the evaporator 12, along a direction perpendicular to the height direction of the evaporator 12, i.e., the length direction of the evaporator 12.

By disposing the first tube sheet 16 on the side of the evaporator 12 in the direction perpendicular to the height direction of the evaporator 12, the first tube sheet 16 can be more easily fixed on the side of the evaporator 12.

In some alternative embodiments, the first tube plate 16 is provided with a mounting portion 161, and the mounting portion 161 extends towards the direction of the duct skeleton 151 and is fixedly connected with the protrusion 1511.

By providing the fitting portion 161 on the first tube plate 16, wherein the fitting portion 161 extends toward the direction of the air duct framework 151, the first tube plate 16 can be fixedly connected with the protrusion 1511 through the fitting portion 161, and the direct connection between the first tube plate 16 and the air duct can be realized.

In fig. 2, the contact surface between the fitting portion 161 and the protrusion 1511 is a plane or a curved surface, as long as the shape of the connection surface between the fitting portion 161 and the protrusion is consistent, so as to prevent the air conditioner from wind cross during operation.

The first tube plate 16 is designed to be a three-section structure, so that the assembly structure is simple, and the first tube plate can be effectively connected with the protrusion 1511, wherein the third section is a tailing left after the assembly portion 161 is processed, in order that the third section does not affect the assembly of the first tube plate 16 and the protrusion 1511, the third section is arranged towards the evaporator 12, the first tube plate 16 is an integrally formed structure, and compared with the structure of the inner tube plate and the outer tube plate in the prior art, the installation process of the assembly structure of the evaporator 12 is simplified.

Of course, the first tube plate 16 may also be designed as a split structure, and the assembling portion 161 is disposed at a position close to the air duct framework 151, that is, on the inner tube plate in the prior art, the assembling portion 161 is integrated with the inner tube plate.

In some alternative embodiments, when the first tube sheet 16 is a unitary structure, the width W2 of the fitting portion 161 and the width W1 of the first tube sheet 16 satisfy:

w1 0.1 is not less than W2 is not less than W1 is not less than 0.3+1, wherein the unit of W1 and W2 are both millimeter.

Wherein the width W1 of the first tube sheet 16 refers to the length in the direction perpendicular to the cross-section of the evaporator 12.

By setting the width W2 of the fitting portion 161 and the width W1 of the first tube plate 16 in such a proportional relationship, the width W2 of the fitting portion 161 can be matched with the width W1 of the first tube plate 16, material waste caused by an excessively long length of the fitting portion 161 is avoided, an ineffective connection between the protrusion 1511 and the fitting portion 161 due to an excessively short length of the fitting portion 161 can also be avoided, and the connection strength between the protrusion 1511 and the fitting portion 161 is ensured.

In some alternative embodiments, when the first tube sheet 16 is a split structure, the width W2 of the fitting portion 161 only needs to satisfy the connection strength requirement with the protrusion 1511. In some alternative embodiments, the width of the assembling portion 161 is the same as or similar to the width of the protrusion 1511, so that the assembling between the two is more convenient, and at the same time, the material is saved, and the production cost of the air conditioner is reduced.

Fig. 6 is a partially enlarged view illustrating the assembly of an evaporator according to still another view of an exemplary embodiment, and as shown in fig. 6, a mounting hole 1621 is provided on the connecting portion 162 at the upper end for fixedly connecting the connecting portion 162 at the upper end with the air duct by using a screw.

In alternative embodiments, the length of the projection 1511 is the same or similar to the length of the first tube sheet 16.

By setting the length of the projection 1511 to be the same as or similar to the length of the first tube sheet 16, fitting of the projection 1511 to the first tube sheet 16 can be made easier and material can be saved.

In some alternative embodiments, the protrusion 1511 is provided with one or more first screw holes 15111 along its length, the first tube sheet 16 is provided with one or more second screw holes along its length, and the first screw holes 15111 are distributed in the same manner as the second screw holes.

More specifically, a second screw hole is provided on the fitting portion 161 so that the projection portion 1511 and the fitting portion 161 are connected by a screw from the first screw hole 15111 and the second screw hole.

When there is one first screw hole 15111, it is provided at an intermediate position in the longitudinal direction of the projection 1511.

By disposing one first screw hole 15111 at an intermediate position in the lengthwise direction of the projection 1511, the fixation of the projection 1511 to the first tube sheet 16 can be made relatively firm.

When there are a plurality of first screw holes 15111, they are uniformly distributed along the length direction of projection 1511, which is an example of a plurality of first screw holes 151111 in fig. 4.

Here, the number of the first screw holes 15111 is set in proportion to the length of the projection 1511.

By uniformly arranging the plurality of first screw holes 15111 along the length direction of the projection 1511, the fixation of the projection 1511 to the first tube plate 16 can be made more firm, and the processing is simple.

In some alternative embodiments, the spacing between adjacent first screw holes 15111 is 1/8-1/3 of the length of projection 1511.

Through setting up 1/8-1/3 that the interval between two adjacent first screw holes 15111 is the length of bulge 1511, can avoid causing when the distance is too big that fixed insecure between bulge 1511 and the first tube sheet 16, also can avoid causing when the distance is too little that first screw hole 15111 is too intensive, lead to the production assembly process complicated, reduce production efficiency.
