Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning component manufacturing technology, and in particular to an automotive dryer bottle condenser. Background Technology

[0002] The main function of automotive air conditioning condenser dryer bottles is to filter impurities inside the condenser and absorb moisture from the refrigerant, ensuring the stable and efficient operation of the air conditioning system. This directly affects the cooling effect and lifespan of the air conditioning system. As an important component of the air conditioning refrigeration system, the core challenge currently facing the manufacturing industry is to achieve high-standard precision machining capabilities and reliable welding seals.

[0003] Currently, most dryer bottle shells are manufactured using ordinary stamping processes, resulting in uneven wall thickness, which easily leads to dimensional deviations and hidden cracks, affecting product strength and reliability. Welding processes are mostly done manually or with semi-automatic tooling, resulting in low clamping efficiency and insufficient positioning accuracy, which can easily cause welding deviations and affect airtightness and consistency. Therefore, we propose a condenser for automotive dryer bottles. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a condenser for automotive dryer bottles, which improves the manufacturing precision and quality stability of dryer bottles, and promotes improvements in product efficiency, durability, and safety.

[0005] The technical solution of this utility model is:

[0006] A car desiccant condenser includes a housing. A front end cap is sealed at one end of the housing, and a rear end cap is sealed at the other end of the housing. An inlet pipe connector and an outlet pipe connector are respectively inserted into the surface of the front end cap, and both the inlet pipe connector and the outlet pipe connector are connected to the interior of the housing. An inlet pipe is provided inside the housing, and two desiccant baffles are also provided at both ends of the interior of the housing. The desiccant baffles are fixed by a limiting ring. The inlet pipe passes through the bottom ends of the two desiccant baffles. The housing is divided into three areas by the two desiccant baffles: an outlet chamber, an empty chamber, and an inlet chamber. A small outlet hole is provided on the inlet pipe in the area of ​​the inlet chamber.

[0007] In a further technical solution, the lower end of the housing forms an independent sealing structure through a rear end cover.

[0008] In a further technical solution, the mating points between the front end cover and the inlet pipe joint and the outlet pipe joint are sealed using double-layer sealing rings.

[0009] In a further technical solution, the surface of the front cover is also provided with blind holes.

[0010] In a further technical solution, the shell is formed by stretching in one step using a special hydraulic press and a special stretching die.

[0011] In a further technical solution, the welding of the front end cover and the rear end cover is completed by a special automatic rotary welding fixture.

[0012] The beneficial effects of this utility model are:

[0013] The shell of this dryer bottle is formed by stretching in one step using a special stretching mold and a hydraulic press, which can ensure uniform wall thickness, controllable dimensional accuracy and avoid the formation of hidden cracks; by setting a special automatic rotary welding fixture, this utility model can realize efficient clamping and automatic welding of the dryer bottle, and is suitable for mass production of dryer bottles for automotive air conditioning condensers.

[0018] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0019] Example:

[0020] like Figures 1-2As shown, a car desiccant bottle condenser includes a desiccant bottle shell 1 and a front end cap 2 and a rear end cap 7 sealed on the port of the shell 1. The front end cap 2 is connected to an inlet pipe connector 3 and an outlet pipe connector 4, both of which are in communication with the interior of the shell 1. The shell 1 is provided with an inlet pipe 5, which has a rectangular hole 8. The refrigerant enters the inlet chamber 13 through the hole 8, is filtered by the desiccant baffle 6, and enters the cavity 12 where the desiccant bag is placed. The desiccant baffle 6 divides the inside of the desiccant bottle into three cavities: an inlet chamber 13 where the rectangular hole at the bottom of the inlet pipe is located, a cavity 12 where the desiccant is placed, and an outlet chamber 11 connected to an outlet pipe. The cavity between the two baffles 6 is used to place bagged desiccant, which then flows into the outlet chamber 11. Finally, after filling the desiccant bottle, it is discharged through the outlet pipe connector 4. The desiccant baffle 6 is fixedly installed in the middle of the shell 1 by a limiting ring 9 to limit the placement position of the desiccant and prevent its displacement during use. The rear end cap 7 is provided at the lower end of the shell 1 to form an independent sealing structure. The front cover 2 is sealed with a double-layer sealing ring 21 at the joint with the inlet pipe connector 3 and the outlet pipe connector 4. The end cover 2 is provided with a blind hole 22 for fixing. The liquid inlet pipe 5 passes through the inside of the shell 1 and has a rectangular hole 8. The condensate enters the bottle from the inlet pipe connector 3 through the liquid inlet pipe 5. The liquid enters the liquid inlet chamber 13 through the hole 8, is filtered by the desiccant baffle 6 and enters the desiccant cavity 12, then flows into the liquid outlet chamber 11, and is finally discharged from the outlet pipe connector 4.

[0021] In another embodiment, the housing 1 is formed by stretching in one step using a special hydraulic press and a special stretching die to ensure uniform wall thickness, controllable dimensional accuracy and no hidden cracks.

[0022] In another embodiment, the welding of the front cover 2 and the rear cover 7 is completed by a special automatic rotary welding fixture. The fixture has limiting and quick locking functions, and completes high-precision welding under automatic rotation conditions, improving airtightness and consistency, and enabling the dry bottle to be quickly clamped and positioned with high precision during the welding process.

[0023] In another embodiment, the manufacturing process of the desiccant includes shell stretching and forming, machining the end interface, assembling internal components, clamping the main body onto the tooling, quickly locking the shell, setting process parameters, and automatic rotary welding.

[0024] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
