Abstract
The utility model relates to a kind of micro-channel heat exchanger, comprise heat sink, heat-transfer pipe, refrigerant inflow port, lower heat sink, it is characterized in that, heat-transfer pipe is set to snakelike point of cloth-like curved pipe, one end of heat-transfer pipe is connected with upper heat sink, the other end of heat-transfer pipe is connected with lower heat sink, and upper heat sink is positioned at the top of lower heat sink and parallel with lower heat sink, and the middle position of lower heat sink is provided with refrigerant inflow port.Advantage: the VELOCITY DISTRIBUTION problem considering air stream, because the central area of heat exchanger has higher air velocity usually, micro-channel heat exchanger is designed to cold-producing medium to be flowed into by central area, improves the traditional design of cold-producing medium from a side inflow, thus improve exchange capability of heat.
Description
Technical field
The utility model relates to a kind of technical field of heat exchange equipment, is specially a kind of micro-channel heat exchanger.
Background technology
Heat exchanger is a kind of common apparatus being widely used in the industries such as chemical industry, petrochemical industry, refrigeration, metallurgy, medicine, power, light industry, therefore the research of heat exchanger attention always, at present, the performance of micro-channel heat exchanger heat exchange is general not high, its weak point is: (1) micro-channel heat exchanger adopts the broken pipe of 90 °, the problem that flow distribution is uneven is not considered in its design, (2) traditional heat exchanger refrigerant is all from a side inflow, its Position Design does not consider the VELOCITY DISTRIBUTION problem of air stream, causes heat exchange efficiency to reduce.
Summary of the invention
The purpose of this utility model is the VELOCITY DISTRIBUTION problem considering air stream, micro-channel heat exchanger is designed to cold-producing medium to be flowed into by central area, thus raising exchange capability of heat, in addition, the broken pipe of 90 ° is replaced by snakelike point of cloth-like curved pipe, the problem that flow distribution is uneven can be improved, therefore, provide a kind of micro-channel heat exchanger.
For achieving the above object, by the following technical solutions, the utility model comprises heat sink 1, heat-transfer pipe 2, refrigerant inflow port 3, lower heat sink 4, it is characterized in that, heat-transfer pipe 2 is set to snakelike point of cloth-like curved pipe, and one end of heat-transfer pipe 2 is connected with upper heat sink 1, and the other end of heat-transfer pipe 2 is connected with lower heat sink 4, upper heat sink 1 is positioned at the top of lower heat sink 4 and parallel with lower heat sink 4, and the middle position of lower heat sink 4 is provided with refrigerant inflow port 3.
The beneficial effects of the utility model are:
(1) the VELOCITY DISTRIBUTION problem of air stream is considered, because the central area of heat exchanger has higher air velocity usually, micro-channel heat exchanger is designed to cold-producing medium to be flowed into by central area, improves the traditional design of cold-producing medium from a side inflow, thus improve exchange capability of heat.
(2) replaced the broken pipe of 90 ° by snakelike point of cloth-like curved pipe, improve the problem that the flow pattern of two phase flow is uneven, improve the heat exchange property of whole heat exchanger.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation
In figure: upper heat sink 1, heat-transfer pipe 2, refrigerant inflow port 3, lower heat sink 4.
Detailed description of the invention
Example 1
A kind of micro-channel heat exchanger, comprise heat sink 1, heat-transfer pipe 2, refrigerant inflow port 3, lower heat sink 4, it is characterized in that, heat-transfer pipe 2 is set to snakelike point of cloth-like curved pipe, one end of heat-transfer pipe 2 is connected with upper heat sink 1, the other end of heat-transfer pipe 2 is connected with lower heat sink 4, and upper heat sink 1 is positioned at the top of lower heat sink 4 and parallel with lower heat sink 4, and the middle position of lower heat sink 4 is provided with refrigerant inflow port 3.
Cold-producing medium flows in lower heat sink 4 from refrigerant inflow port 3, by lower heat sink 4, cold-producing medium is sent in the central area of heat-transfer pipe 2, by the central area of heat-transfer pipe 2, cold-producing medium is sent in upper heat sink 1 again, cold-producing medium left and right in upper heat sink 1 is uniformly distributed flowing, and heat exchange is carried out in the right and left region finally flowing into heat-transfer pipe 2.
