Abstract
The utility model discloses a multi-hole flat pipe, which is made of an aluminum extruded profile. The cross section of the flat pipe is oblong-shaped, and 21 round holes with the phi of 0.5mm are arranged in the pipe. The multi-hole flat pipe has the advantages that the pipe has light weight and high heat conduction performance; the pressure resistance performance of the round-hole micro-channel structure is better; and the pipe can be used in an automobile air conditioner parallel flow heat exchanger, so that the product structure is more compact and the number of the multi-hole flat pipes arranged per unit area is more, which is helpful for reducing the weight of parts and components of the parallel flow heat exchanger.
Description
Technical field
The utility model relates to the thermal component that a kind of automobile air conditioner parallel flow heat exchanger is used, and in particular, particularly a kind of automobile air conditioner parallel flow heat exchanger that is applied to comprises the porous flat pipe that parallel flow condenser and parallel-flow evaporator are used.
Background technology
The automobile air conditioner parallel flow heat exchanger comprises condenser and evaporimeter, and main thermal component and the refrigerant diversion component of forming heat exchanger core body are porous flat pipes.At present, the porous flat pipe cross section of widespread usage is thick * and it is wide that (H * B) is 1.7mm * 16mm, 2mm * 16mm, is square hole in the pipe, is applied to parallel-flow heat exchanger, and its product specification size is bigger, and the unit front face area that takies heat exchanger is many, the product weight weight.
The utility model content
The purpose of this utility model is in order to solve the problem of above-mentioned existence, and a kind of in light weight, volume is little, the unit volume heat transfer property is high porous flat pipe is provided.
The utility model is achieved through the following technical solutions.
The utility model is a kind of porous flat pipe, and described porous flat pipe is made by aluminium matter extrudate, and its shape of cross section is oblong, the circular hole that to be provided with 21 specifications in the pipe be Φ 0.5mm.
Above-mentioned shape of cross section specification is thick * the wide 1.1mm * 16mm that is of a size of;
21 circular holes that are provided with in the aforementioned tube are in-line to be arranged, and the interval between each circular hole equates.
Advantage of the present utility model is, and is in light weight, heat conductivility is high; The withstand voltage properties of circular hole MCA is better, is applied to the automobile air conditioner parallel flow heat exchanger and makes product structure compacter, and the porous flat pipe that unit are is arranged is more, helps the lightweight of parallel-flow heat exchanger parts.
Description of drawings
Fig. 1 is a cross-sectional structure schematic diagram of the present utility model;
Fig. 2 is an overall structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in the figure, the utility model is a kind of porous flat pipe, described porous flat pipe 1 is made by aluminium matter extrudate, its cross section 2 shapes are oblong, oblong specification is thick * the wide 1.1mm * 16mm that is of a size of, 11 circular holes 3 of circular hole that to be provided with 21 specifications in the pipe be Φ 0.5mm 3, two are in-line to be arranged, and the interval between each circular hole 3 equates.
21 circular holes 3 that specification is φ 0.5mm have improved the heat transfer area of refrigerant and porous flat pipe 1, have higher withstand voltage and bursting property than square hole.In the practical application, porous flat pipe 1 is communicated with header and forms airtight flow cycle through soldering, and the dividing plate that the heat exchange medium are provided with in header forms certain workflow.Circular hole 3 circulations of two ten one the φ 0.5mms of heat exchange medium in porous flat pipe 1, logical peraluminous tube wall heat is passed to radiating fin and porous flat pipe 1 ambient air, thereby realizes that aluminium matter porous flat pipe 1 is applied to the heat transfer process of parallel-flow heat exchanger.
