Embodiment 1

[0020] Embodiment 1, see attached Figure 1-5 :

[0021] Such as figure 1 As shown, the present invention provides an evaporator, comprising: a distribution pipe 1, a liquid collection pipe 2 and several microchannel flat pipes 3, wherein: the distribution pipe 1 and liquid collection pipe 2 are vertical and Placed in parallel at a certain distance, several microchannel flat tubes 3 evenly arranged in parallel are embedded between the distribution pipe 1 and the liquid collection pipe 2 . The two ends of each flat tube 3 are respectively connected with the distribution tube 1 and the liquid collection tube 2, and there are several micro-channels evenly distributed in the flat tubes for the flow of refrigerant, and the hydraulic radius of the micro-channels is 0.5mm. Fins 6 for heat dissipation are arranged between adjacent flat tubes; see image 3 , the surface of the fin 6 has heat dissipation protrusions arranged in an array, and the protrusion includes an inclined sectio...

Abstract

The invention provides car air-conditioner refrigerating equipment. The car air-conditioner refrigerating equipment comprises an evaporator, and the evaporator comprises a distribution pipe, a liquid collecting pipe and a plurality of micro passageway flat pipes; the liquid collecting pipe and the distribution pipe are placed in parallel; the micro passageway flat pipes are mounted between the liquid collecting pipe and the distribution pipe in an embedded mode, and fin plates for heat dissipation are arranged between every two adjacent flat pipes; a plurality of micro passageways for fluid flowing are formed in each flat pipe, and the fin plates for heat dissipation are arranged between every two adjacent flat pipes and characterized in that the surfaces of the fin plates are provided with heat dissipation protrusions arranged in an arrayed mode, each protrusion comprises an oblique section and an arc-shaped section, and in the air flowing direction, the oblique section is located at the upper stream; and the distance between every two adjacent protrusions is X, the length of each protrusion is Y, and X=(0.35-0.5)Y.

Description

technical field [0001] The invention relates to a device in the technical field of automobile air-conditioning and refrigeration, in particular to an automobile air-conditioning and refrigeration equipment. Background technique [0002] Microchannel technology is widely used in the field of refrigeration, especially in automotive air conditioning. Compared with the traditional tube-fin evaporator, the micro-channel evaporator has the advantages of high heat transfer coefficient, small size, light weight, less refrigerant charge and greatly reduced cost. However, the microchannel evaporator has the problem of the distribution uniformity of the two-phase refrigerant. The specific manifestations are: the distribution of superheat at the outlet of the microchannel flat tube is uneven, and the flow rate and dryness of the refrigerant distributed to each flat tube are quite different. For example, the superheat of the refrigerant at the outlet of some microchannel flat tubes is r...
