Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
In the present invention, unless otherwise specified, the directional terms "bottom end, top end," and the like included in the terms merely represent the orientation of the terms in a conventional use state or a colloquial meaning understood by those skilled in the art, and should not be construed as limiting the terms.
Referring to fig. 1, the present invention provides a receiver-drier assembly comprising a receiver-drier, a base 9 and a cooling mechanism; the liquid storage dryer is detachably arranged on the top surface of the base 9, the cooling mechanism is arranged on one side or two sides of the liquid storage dryer and can cool the outer wall of the liquid storage dryer; the receiver-drier comprises a drier body having a refrigerant inlet 1 and a refrigerant outlet 5; a cavity is formed in the dryer body, an outlet pipe 4 is arranged in the cavity along the axial direction, one end of the outlet pipe 4 is connected with a refrigerant outlet 5, and the other end of the outlet pipe extends towards the bottom end of the cavity; two filter screens 2 are sleeved outside the leading-out pipe 4, and a drying agent 3 is arranged between the two filter screens 2; wherein, the top end of the eduction tube 4 extends towards the top end of the dryer body to form an observation channel, and a liquid viewing mirror 10 is arranged on the top end sealing cover of the observation channel.
Through above-mentioned technical scheme, establish the receiver drier on the top surface of base 9 to install base 9 to the preset position in the vehicle air conditioning system, can improve the stability after the installation of whole receiver drier subassembly like this. Simultaneously, still be equipped with on base 9 pertinence and carry out refrigerated cooling body to stock solution desicator outer wall, because cooling body's existence for the heat that stock solution desicator produced in the use can in time spread, can not make the drying bottle be in under the higher temperature always and take place to damage near its gathering, has prolonged stock solution desicator's life intangibly, has reduced vehicle air conditioner's maintenance cost. Therefore, the refrigerant coming out of the condenser enters the liquid storage dryer through the refrigerant inlet 1, firstly impurities in the refrigerant are filtered through the filter screen 2, and then the moisture in the refrigerant is absorbed through the drying agent 4, so that the phenomenon that the pipeline of the refrigeration system is dirty and blocked is prevented, the bottom of the cavity of the liquid storage dryer can be used for storing redundant liquid refrigerant, the quantity of the refrigerant needed by the automobile air conditioning system can be timely supplemented and adjusted, and the phenomenon that the excessive refrigerant stays in the condenser to influence the heat dissipation effect can be prevented. Finally, the liquid refrigerant enters the throttle expansion device through the outlet pipe 4 via the refrigerant outlet 5. Moreover, an operator can directly see the flow condition in the liquid storage dryer from the outside through the liquid viewing mirror 10, and if continuous bubbles are found in the liquid storage dryer through observation, the entering amount of the refrigerant is insufficient; if no bubbles are visible, this indicates an excess of refrigerant; a moderate amount of refrigerant entering the receiver-drier is only indicated when the operator finds that there are few bubbles inside.
In this embodiment, in order to increase the cooling effect of the cooling mechanism and simplify the mechanical structure of the cooling mechanism, it is preferable that the cooling mechanism includes a cooling collar 7, and the cooling collar 7 is sleeved outside the receiver-drier.
The cooling collar 7 may be any cooling mechanism that is commonly used in the art and can achieve a cooling effect, but from the viewpoint of controlling the production cost and facilitating subsequent repair and replacement, the cooling collar 7 is preferably a ring-shaped refrigeration plate.
In addition, in order to further increase the air flow near the receiver-drier to timely remove the heat generated by the receiver-drier and prevent the receiver-drier from overheating due to heat accumulation, the cooling mechanism preferably further comprises a fan 8; wherein, a plurality of through-holes have been seted up on the wall of cooling lantern ring 7, and the direction of blowing of fan 8 sets up to pass the through-hole and towards the outer wall of receiver drier.
Since the refrigerant is continuously supplied into the receiver-drier through the refrigerant inlet 1, which causes the pressure in the receiver-drier to rise continuously, in order to prevent the refrigerant from flowing back and damaging the refrigeration system, the receiver-drier preferably further includes a fusible plug 6, and the fusible plug 6 is disposed at the top end of the drier body. Thus, when the high-pressure side of the fusible plug 6 reaches the limit of the pressure, the fusible alloy in the fusible plug 6 melts by itself, so that the refrigerant can directly release excessive refrigerant into the atmosphere, and the refrigeration system is prevented from being damaged.
In this embodiment, in order to increase the stability of being connected between receiver drier and base 9, convenient to detach receiver drier carries out the gas tightness simultaneously and detects and reinstall to the base on, preferably, be equipped with the external screw thread on receiver drier's the bottom outer wall, the top surface part of base 9 is inwards sunken to be formed with the internal thread hole with external screw thread matched with.
In the above installation process, in order to prevent the installation contact part between the receiver drier and the base 9 from slipping and being inconvenient to install, a rubber ring is preferably formed between the internal thread hole and the external thread.
The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, however, the present invention is not limited to the specific details of the above embodiments, and various simple modifications can be made to the technical solution of the present invention within the technical idea of the present invention, and these simple modifications are within the protective scope of the present invention.
