Description

Technical Field

[0001] The utility model relates to the technical field of automobile radiators, and particularly relates to a main plate structure of an automobile radiator water chamber. Background Technique

[0002] An automobile radiator is composed of three parts: an inlet water chamber, an outlet water chamber and a radiator core. The coolant flows inside the radiator core, and air passes outside the radiator. The hot coolant is cooled by dissipating heat to the air, and the cold air is heated by absorbing the heat dissipated by the coolant.

[0003] A connection structure between a main plate and a water chamber provided by the publication number "CN211739991U" assembles the main plate with a heat dissipation tube, a heat dissipation belt and a reinforcing plate to complete the core body, then inserts the main plate into the card slot of the clamping part at the opening end of the water chamber, and then pushes the water chamber to make the center of the water chamber coincide with the center of the core body; then presses the clamping part and the main plate inside through a pressing tooling. After pressing is completed, the bent part of the end plate of the water chamber is manually pressed into the inner cross section at both ends of the water chamber; then powder spraying is carried out, and finally it is put into a brazing furnace for brazing forming.

[0004] However, the above technical solution and the existing technologies have the following defects:

[0005] Although the connection structure between the radiator main plate and the water chamber connects the main plate and the water chamber through a brazing connection method, so as to ensure the connection stability at the connection between the main plate and the water chamber, this connection method cannot disassemble and replace the water chamber separately in the later stage. Once the water chamber is deformed and damaged, it is necessary to replace the main plate and the radiator core body together, which increases the maintenance cost of the user. Secondly, the radiator water chamber does not have a corresponding reinforcement structure to strengthen its anti-deformation ability. Since the automobile will generate bumps and vibrations during driving, and the water chamber structure is thin, the water chamber is prone to cracking and damage under long-term vibrations, and there is room for improvement in terms of service life. Content of the Utility Model

[0006] The purpose of the utility model is to provide a main plate structure of an automobile radiator water chamber to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] A main sheet structure of an automobile radiator water chamber, comprising an automobile radiator core, an upper main sheet, an upper water chamber, a mounting plate, a lower main sheet and a lower water chamber. The upper end of the automobile radiator core is fixedly connected with the upper main sheet, the upper water chamber is installed on the upper end face of the upper main sheet, the lower end face of the automobile radiator core is fixedly connected with the lower main sheet, the lower water chamber is installed on the lower end face of the lower main sheet, the left and right end faces of the automobile radiator core are symmetrically and fixedly connected with mounting plates. Reinforcing components are arranged on the outer surfaces of the upper water chamber and the lower water chamber, and the reinforcing components are used to further improve the anti-deformation ability of the upper water chamber and the lower water chamber. Sealing connection components are arranged at the joints of the upper water chamber and the upper main sheet and at the joints of the lower water chamber and the lower main sheet, and the sealing connection components are used to further improve the sealing performance at the joints of the upper water chamber and the upper main sheet and at the joints of the lower water chamber and the lower main sheet.

[0009] Preferably, the sealing connection component includes a primary sealing strip, a secondary sealing strip, a fixed insertion piece, a mounting groove and a fixing screw. The primary sealing strips are installed on the lower end face of the upper water chamber and the upper end face of the lower water chamber. The secondary sealing strips are embedded on the outer walls of the upper water chamber and the lower water chamber. Mounting grooves are symmetrically formed on the front, rear, left and right end faces of the upper water chamber and the front, rear, left and right end faces of the lower water chamber. The fixed insertion pieces are inserted into the mounting grooves, and the fixing screws are installed inside the fixed insertion pieces.

[0010] Preferably, an internally threaded through hole is formed inside the fixed insertion piece. Liquid guiding through holes are symmetrically formed on the left, right, front and rear end faces of the upper water chamber and the left, right, front and rear end faces of the lower water chamber, and the liquid guiding through holes are communicated with the secondary sealing strips.

[0011] Preferably, the reinforcing component includes external longitudinal reinforcing ribs, transverse reinforcing ribs and external arc-shaped reinforcing ribs. A plurality of external longitudinal reinforcing ribs are arranged on the upper end face of the upper water chamber and the lower end face of the lower water chamber. A plurality of transverse reinforcing ribs are arranged between the plurality of external longitudinal reinforcing ribs.

[0014] Preferably, the mounting groove matches the fixed insertion piece, and the material of the fixing screw is a locknut.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. By installing the sealing strip once, the sealing performance between the upper water chamber and the upper main plate and between the lower water chamber and the lower main plate can be ensured. The liquid guiding through holes can introduce a part of the coolant in the upper water chamber and the lower water chamber into the secondary sealing strip, causing the moisture-absorbing expansion and deformation of the secondary sealing strip, thereby further improving the sealing performance between the upper water chamber and the upper main plate and between the lower water chamber and the lower main plate, and avoiding the leakage of the coolant in the upper water chamber and the lower water chamber. When the fixing screws are loosened and removed, the fixing inserts can be pulled out for disassembly. At this time, the upper water chamber and the lower water chamber can be disassembled, replaced or maintained separately, thereby reducing the later maintenance cost for the users.

[0017] 2. By respectively arranging the external longitudinal reinforcing ribs, transverse reinforcing ribs and internal longitudinal reinforcing ribs, the outer walls and inner walls of the upper water chamber and the lower water chamber can be strengthened. The external arc-shaped reinforcing ribs and internal arc-shaped reinforcing ribs can strengthen the bending parts of the upper water chamber and the lower water chamber, so that the strength and anti-deformation ability of the upper water chamber and the lower water chamber are better, avoiding the deformation and cracking of the upper water chamber and the lower water chamber during use, and thus improving the service life of the upper water chamber and the lower water chamber.
