Abstract

The utility model relates to a vehicle air conditioner adopting liquid storing drier, with a structure that a drying agent and a filtering felt are fixed in the pot body by a left halftone and a right halftone; the right halftone and the pot body are connected with a pinch point method; an educing pipe is integrated with the pot body; the pot bottom and the pot body are welded together when in assembling; a spring and the left halftone are arranged at the top of the liquid storing drier by adopting clearance matching; one end of the educing pipe is provided with a base which is arranged on one end of the educing pipe by adopting clearance matching. The utility model has the advantages that the spring and a floating type halftone are arranged at the top of the liquid storing drier by adopting clearance matching to overcome the abrasion loss of the drying agent caused by the vibration; a base is added to one end of the educing pipe to prevent the fallen out drying agents in the sudden fault from entering the air condition system. The base adopts transition matching to be arranged on one end of the educing pipe and the distance from the pot bottom is very small to absorb the liquid refrigeration agent at the bottom of the pot body.

Description

Used for automobile air conditioning liquid storage dryer

Technical field

The utility model relates to a kind of liquid storage dryer of used for automobile air conditioning, it can flow into liquid refrigerant from the import of liquid storage dryer, and felt filters and desiccant absorption moisture after filtration, flows out from outlet and supplies with evaporator.Belong to automotive air-conditioning system component technology field.

Background technology

Its structure of prior art as shown in Figure 1.Desiccant be that two blocks of web plates are fixed about relying on.Web plate is connected with transition fit with tank body, and web plate is fixed in the tank body, jar end and tank body when assembling, weld together.Web plate is that desiccant and filter felt are fixed in the tank body.In the liquid storage dryer, inevitably there is the gap in loose packed granulated dried agent a part sieve, phase mutual friction between the molecular sieve when being subjected to vibrating, cause molecular sieve to wear and tear gradually, particle diminishes, efflorescence, it is big that gap between sieve particle constantly becomes, and fixedly the web plate of desiccant links with tank body when assembling tightly regularly, and the gap that becomes big is gradually reduced, mutually friction and collision are more serious between the molecular sieve, and it is more and more faster to wear and tear.Molecular sieve after the efflorescence will filter felt and system pipeline seriously stops up, and finally causes a/c system to lose efficacy because of obstruction.Big at Oscillation Amplitude, this phenomenon is more obvious on the high diesel-engine vehicles of oscillation frequency.

Summary of the invention

The purpose of this utility model is the defective of depositing at above-mentioned, proposes a kind ofly can effectively overcome desiccant because of being subjected to vibrating the abrasion that cause.Technical solution of the present utility model: its structure is that desiccant is fixed in the tank body by left and right web plate with the filter felt, right web plate is connected with the method for tank body with the folder point, fairlead and tank body are one, the jar end and tank body be weld together when assembling, spring and left web plate use free-running fit to be contained in the top of liquid storage dryer, one end of fairlead has a base, and base adopts transition fit to be assemblied in an end of fairlead.Advantage of the present utility model: spring and a floating type web plate use free-running fit to be contained in the top of liquid storage dryer, overcome desiccant because of being subjected to vibrating the abrasion that cause, end at fairlead increases a base, has prevented that the desiccant that product is scattered when chance failure occurring from entering a/c system.An end and the distance at jar end that base employing transition fit is assemblied in fairlead are very little, are used for drawing the liquid refrigerant of tank base.

Description of drawings

Accompanying drawing 1 is the prior art structural representation.

Accompanying drawing 2 is structural representations of the present utility model.

Among the figure 1, the 2nd, left and right web plate, the 3rd, desiccant, the 4th, tank body, the 5th, fairlead, the 6th, at the bottom of jar, the 7th, filter felt, the 8th, spring, the 9th, base.

The specific embodiment

The reservoir principle of work: liquid refrigerant flows into from the import of liquid storage dryer, and felt filters and desiccant absorption moisture after filtration, flows out from outlet and supplies with evaporator.

Contrast accompanying drawing 2, desiccant 3 be that two blocks of web plates 1,2 are fixing about relying on.Web plate 1 is connected with tank body 4 usefulness free-running fits, and the rise method of (folder) pressure point of web plate 2 usefulness is fixed in the tank body (fairlead 5 and tank body 4 for one), jar end 6 and tank body 4 when assembling, weld together.Desiccant wherein is used for absorbing the moisture in the liquid refrigerant.The effect of filter felt 7 is the impurity that filters in the refrigerant.Tank body 4 is to be used for storing unnecessary liquid refrigerant with a jar end 6, bears system pressure simultaneously, and guarantees that liquid refrigerant is not to external leakage.Web plate 1,2 effects are that desiccant 3 and filter felt 7 are fixed in the tank body 4.For overcoming desiccant because of being subjected to vibrating the abrasion that cause, we use free-running fit to be contained in the top of liquid storage dryer on spring 8 and a floating type web plate 1, make desiccant 3 by push-tight, to eliminate the gap of causing in the assembling between the desiccant.Desiccant 3 is being subjected to vibrating the back if the gap, and spring 8 will promote web plate 1 automatically and eliminate the gap, reducing the friction between desiccant particle, thereby reduces the abrasion of desiccant 3.End at fairlead 5 (part of tank body) increases a base 9, and when being used for preventing that chance failure from appearring in product, the desiccant that is scattered enters a/c system.An end and the distance at jar end that base 9 employing transition fit are assemblied in fairlead 5 are very little, are used for drawing the liquid refrigerant of tank base.Spring: when the gap appears in desiccant in vibration, spring is given a thrust and is promoted movable screen 1.Movable screen 1 relies on spring 8 thrusts to eliminate the gap that desiccant occurs in vibration, and better fixing desiccant reduces friction each other.When base 9 prevented chance failure, desiccant 3 entered system.

Claims

1, used for automobile air conditioning liquid storage dryer, it is characterized in that desiccant (3) and filter felt (7) are fixed in the tank body (4) by left and right web plate (1), (2), right web plate (2) is connected with the method for tank body (4) with the folder point, fairlead (5) is an one with tank body (4), the jar end (6) and tank body (4) weld together when assembling, spring (8) and left web plate (1) use free-running fit to be contained in the top of liquid storage dryer, one end of fairlead (5) has a base (9), and base (9) adopts transition fit to be assemblied in an end of fairlead (5).
