Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning condenser installation, in particular to a transition bracket for fixing an automobile air-conditioning condenser. Background Art

[0002] The condenser is an important heat dissipation module of the automobile air-conditioning system. In order to dissipate heat, the condenser is usually installed and fixed on the automobile water tank. The existing automobile air-conditioning condenser installation and fixing methods generally include metal bracket fixing method and bolt fixing method. Among them, the metal bracket fixing method is to directly braze two metal brackets on the collecting pipes on both sides of the automobile air-conditioning condenser, and the metal brackets are then fixed to the water tank by self-tapping screws or bolts, so as to fix the condenser on the water tank. The installation process is relatively complicated. The bolt fixing method is to fix the condenser to the car body or water tank by bolting. In this way, not only the corresponding installation holes must be opened on the water tank and the condenser, but also the installation is not convenient enough. Utility Model Content

The condenser includes a collecting pipe and a flat tube, and includes a plastic bracket. The plastic bracket includes a cylindrical structure and a groove structure. The cylindrical structure is composed of two arc cylinders arranged opposite to each other. A hollow portion is opened on the arc cylinder. A protrusion is arranged on the top wall of the hollow portion. A trapezoidal block is installed on the inner surface of the protrusion. The hypotenuse of the trapezoidal block is arranged upward. An annular boss is arranged on the outer surface of the bottom of the collecting pipe. When the bottom of the collecting pipe is inserted into the cylindrical structure, the upper surface of the annular boss abuts against the lower surface of the trapezoidal block. A conical pin is arranged at the bottom of the groove structure.

[0005] A further solution is that a first groove is formed at the bottom of the collecting pipe, and a cross ring boss matched with the first groove is provided at the bottom of the cylindrical structure.

[0006] A further solution is that reinforcing ribs are installed on the outer surface of the groove structure, and edge reinforcement treatment is simultaneously adopted at the connection between the upper edge of the groove structure and the reinforcing ribs.

[0007] A further solution is that a second groove is formed on the bottom wall of the groove structure at a position corresponding to the conical pin.

[0008] A further solution is that the cylindrical structure and the groove structure are integrally injection molded.

[0009] A further solution is that the outer surface of the annular boss is provided with an extension portion extending into the interior of the groove structure, the extension portion is embedded in a flat tube guard plate below the flat tube, and the lower surface of the flat tube guard plate abuts against the bottom wall of the groove structure.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model forms a snap-on structure by matching the trapezoidal blocks on the arc cylinder of the cylindrical structure with the circular boss of the manifold, and at the same time, the beveled edge of the trapezoidal blocks is set upwards, which plays a guiding role when installing the manifold and the transition bracket; wherein the trapezoidal blocks are provided with hollow parts corresponding to the bottom, so that the trapezoidal blocks have plastic elasticity during the installation process with the manifold, and can move outward, and the manifold and the transition bracket rebound after being snap-fitted and assembled in place, so that the transition bracket and the manifold are easy to assemble, and the transition bracket is matched with the mounting hole of the water tank through the conical pin, so as to facilitate the fixing of the condenser on the water tank.

[0022] See also Figure 1-Figure 6The utility model provides a transition bracket for fixing a car air-conditioning condenser, which is applied to the condenser 1 of the car air-conditioning. A collecting pipe 11 is provided at each end of the condenser 1 of the car air-conditioning. The refrigerant enters the collecting pipe 11 through the pipe joint, and then is divided into the elliptical flat tube 12, and flows in parallel to the opposite collecting pipe 11. In this embodiment, a transition bracket is clamped at the bottom end of the collecting pipe 11 at both ends of the condenser 1, so that the condenser 1 can be installed on the water tank through the transition bracket. Specifically, the transition bracket includes a plastic bracket 2, and the plastic bracket 2 includes a cylindrical structure 21 and a groove structure 22. The cylindrical structure 21 and the groove structure 22 are formed by one-time injection molding, and the manufacturing cost is low. The cylindrical structure 21 is formed by two arc cylinders arranged opposite to each other, and a hollow portion 211 is provided on the arc cylinder, and a protrusion 212 is provided on the top wall of the hollow portion 211. A trapezoidal block 213 is installed on the inner surface of the protrusion 212, and the hypotenuse of the trapezoidal block 213 is arranged upward. The outer surface of the bottom of the manifold 11 is provided with an annular boss 111. When the bottom of the manifold 11 is inserted into the cylindrical structure 21, the upper surface of the annular boss 111 abuts against the lower surface of the trapezoidal block 213. By matching the trapezoidal block 213 on the arc cylinder of the cylindrical structure 21 with the annular boss 111 of the collecting pipe 11, a snap-on structure is formed, and at the same time, the hypotenuse of the trapezoidal block 213 is arranged upward, which plays a guiding role when the collecting pipe 11 and the transition bracket are installed; wherein the trapezoidal block 213 has a hollow portion 211 corresponding to the bottom, so that the trapezoidal block 213 has plastic elasticity during the installation process with the collecting pipe 11, and can move outward, and the collecting pipe 11 and the transition bracket rebound after being snap-fitted and assembled into place, so that the transition bracket and the collecting pipe 11 are easy to assemble; and the transition bracket is formed by one-time injection molding, which is low in cost.

[0023] Preferably, a conical pin 223 is provided at the bottom of the groove structure 22, and the conical pin 223 matches the mounting hole on the water tank.
