Abstract

The utility model relates to an automobile air conditioner evaporator with a flow equalizing pipe, which relates to an automobile air conditioner evaporator, and aims at solving the technical problem for providing an automobile air conditioner evaporator with the flow equalizing pipe enabling refrigerant in the evaporator to flow uniformly. The utility model adopts the technical scheme that the automobile air conditioner evaporator with the flow equalizing pipe comprises an inlet nozzle, an outlet nozzle, an inlet collection pipe, an outlet collection pipe, a flat pipe fin and a communication pipe, and the automobile air conditioner evaporator also comprises a flow equalizing plate and a balance plate; the flow equalizing plate is installed in the inlet collection pipe to form the flow equalizing pipe, and the flow equalizing plate is provided with a plurality of flow equalizing holes; and the balance plate is installed in the outlet collection pipe to form a balance pipe, and the balance plate is provided with a plurality of outlet holes. The utility model is applied to the automobile air conditioner evaporator. The automobile air conditioner evaporator has the beneficial effects that the refrigerant in the evaporator can be enabled to flow uniformly, so that the refrigerating efficiency is improved under the condition that the input power of the evaporator is not increased.

Description

The automobile air-conditioning evaporator that the current-sharing pipe is arranged

Technical field

The utility model relates to a kind of automobile air-conditioning evaporator.

Background technology

The prior art automobile air-conditioning evaporator comprises import mouth, outlet mouth, inlet header, outlet header and flat tube, and cold-producing medium is entered by the import mouth, through inlet header, flat tube and outlet header, is flowed out by outlet mouth; Automobile air-conditioning evaporator has two kinds, and a kind of is stacked, and a kind of is parallel flow type, and laminated evaporator is high because dropping into, complex process, and the trend that is replaced by technique parallel flow evaporators simple, applied widely is gradually arranged.The weak point of prior art automobile air-conditioning evaporator is, flow inhomogeneous at the evaporimeter inner refrigerant, namely larger near flow in the flat tube of import mouth, and less away from the flow in the flat tube of import mouth, thereby affect the utilization rate of the heat exchange area of evaporimeter.

Summary of the invention

Technical problem to be solved is that a kind of mobile automobile air-conditioning evaporator that the current-sharing pipe is arranged uniformly of evaporimeter inner refrigerant that makes is provided.

Solve the technical scheme of its technical problem, comprise import mouth, outlet mouth, inlet header, outlet header, flat tube, fin and communicating pipe, also comprise homogenizing plate and balance plate; Homogenizing plate is contained in inlet header, inlet header is divided into the obstructed two parts in up and down, homogenizing plate consists of the current-sharing pipe with the inlet header housing of close import mouth, several its diameters is arranged according to the distance equal discharge orifice from small to large of distance import mouth on the axis of homogenizing plate; Balance plate is contained in the outlet header, and the outlet header is divided into the obstructed two parts in up and down, and balance plate consists of balance pipe, the outlet opening that has quantity to equate with the current-sharing hole count with the outlet header housing of close outlet mouth on the axis of balance plate; Play the connection effect communicating pipe.

In work, cold-producing medium enters flat tube by the import mouth by the equal discharge orifice on the current-sharing pipe, because the diameter near the equal discharge orifice of import mouth is less, diameter away from the equal discharge orifice of import mouth is larger, therefore make the refrigerant flow basis equalization at this two place that flows through, make the flow basis equalization of cold-producing medium in evaporimeter, thereby make evaporimeter give full play to its refrigerating efficiency.

Beneficial effect: the utility model is applied to automobile air-conditioning evaporator.Beneficial effect is, can make flowing evenly of evaporimeter inner refrigerant, makes evaporimeter under the condition that does not increase input power, and its refrigerating efficiency is improved.

Description of drawings

Fig. 1 is structure chart of the present utility model.In Fig. 1,1 is the import mouth, and 2 is outlet mouth, and 3 is inlet header, and 4 are the outlet header, and 5 is flat tube, and 6 is fin, and 7 is homogenizing plate, and 8 are the current-sharing pipe, and 9 is equal discharge orifice, and 10 is balance plate, and 11 is balance pipe, and 12 is outlet opening, and 13 is communicating pipe.

The specific embodiment

The utility model comprises import mouth 1, outlet mouth 2, inlet header 3, outlet header 4, flat tube 5, fin 6, homogenizing plate 7 and balance plate 9; Homogenizing plate 7 is contained in inlet header 3, inlet header 3 is divided into the obstructed two parts in up and down, current-sharing pipe 8 consists of current-sharing pipes 8 with inlet header 3 housings of close import mouth 1, equal discharge orifice 9 is arranged on homogenizing plate 7, take width 200mm evaporimeter as example, have 5 on homogenizing plate 7 axis at a distance of the equal discharge orifice 9 of 40mm, it is 2mm .3mm .3mm, 4mm, 5mm that its diameter is pressed apart from import mouth 1 distance distance; Balance plate 10 is contained in outlet header 4, outlet header 4 is divided into the obstructed two parts in up and down, balance plate 10 consists of balance pipes 11 with outlet header 4 housings of close outlet mouth 2, and balance plate has 5 to be the outlet opening 12 of 4mm at a distance of the 40mm diameter on 10 axis; Communicating pipe 13 is played the connection effect.
