Description

Technical Field

[0001] The utility model relates to the technical field of liquid storage dryers, in particular to an energy-saving and noise-reducing automobile air-conditioning liquid storage dryer. Background Art

[0002] The automobile air conditioning liquid storage dryer is located between the condenser and the expansion valve. It has two functions: one is to absorb moisture in the refrigeration system, and the other is to provide storage space for the accumulated liquid refrigerant when the expansion valve reduces the flow rate of the liquid refrigerant.

[0003] At present, the liquid storage dryers on cars are all disposable, which not only increases the daily maintenance cost of the car, but also wastes resources and does not meet the current energy-saving and environmental protection requirements. In addition, the single-pass filter cotton structure will reduce the filtering effect after a period of use, affecting normal use. Utility Model Content

[0006] Technical Solution

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] The utility model provides an energy-saving and noise-reducing automobile air-conditioning liquid storage dryer, comprising a dryer, wherein the dryer comprises a tank body and a top cover, the top cover being fixed to the top end of the tank body, a hollow mesh mounting frame being clamped at the inner middle section of the tank body, filter cotton being inserted and fixed in the mesh mounting frame, a bottom block being provided at the bottom end of the tank body, an inlet and a return port being provided in the middle portion of the top cover, a return pipe being fixed to the middle portion of the bottom end of the top cover, one end of the return pipe passing through the mesh mounting frame and being arranged at the top of the bottom block, and the other end being connected to the return port, and a secondary filter element being inserted and fixed at the bottom end of the return pipe.

[0009] Furthermore, a fixing clamp is fixed to the outside of the tank body, and the cross-section of the fixing clamp is a non-closed structure that is a combination of a circle and a fan. A hollow connecting plate is fixed to the outer end of the fixing clamp, and a hole groove structure is also opened in the middle of the fan-shaped structure.

[0010] Furthermore, the top cover and the tank body are engaged and fixed by a threaded structure provided on the side wall, and the secondary filter element and the return pipe are also engaged and fixed by the side wall thread.

[0011] Furthermore, multiple groups of circular hole groove structures are provided at both upper and lower ends of the mesh mounting frame, and a retaining ring structure is fixed on the outer side of the return pipe, and the mesh mounting frame is erected on the top of the retaining ring.

[0012] Furthermore, a trumpet-shaped frustum-shaped groove is provided downwardly at the top of the bottom block, and the bottom end of the bottom block is fitted with the inner wall of the tank body.

[0013] Furthermore, the bottom end of the secondary filter element is trumpet-shaped with a larger upper portion and a smaller lower portion, and a plurality of hole groove structures are provided in the middle of the secondary filter element to achieve communication between the interior of the tank body and the reflux pipe.

[0014] Beneficial effects

[0015] Compared with the known public technologies, the technical solution provided by this utility model has the following beneficial effects:

[0016] The utility model provides an integrated tank structure, in which the tank body and the tank bottom are an integrated structure, and the pressure bearing capacity is greatly enhanced. At the same time, the bottom cover at the bottom of the tank body is cancelled, the parts are reduced, and the cost is reduced. In the tank body, the filter cotton is placed in a mesh mounting frame, which can be connected and fixed to the return pipe-top cover. Therefore, when replacing, the filter cotton structure can be taken out together through the top cover, thereby achieving the effect of quick replacement. At the same time, the secondary filter element structure provided at the bottom of the return pipe can perform secondary filtration. The liquid after the secondary filtration enters the return pipe through the secondary filter element and then flows out through the reflux port, meeting the requirements of use. Finally, in this case, since the bottom block is provided at the bottom of the tank body, its structural characteristics can make the reflux speed faster during reflux, and will act on the outside of the hole groove of the secondary filter element with stronger pressure, thereby improving the filtering effect.
