Description
Technical field
The utility model relates to technical field of central air, and in particular to a kind of airflow circulating type diffuser design.
Background technique
Central air-conditioning is the equipment of central refrigerating and heating, is sent to cold wind or hot wind by pipeline and needs climate comfort
Interior, it is not all right that the cold wind of central air-conditioning or hot wind, which is directly blown into user room, by air piping, generally in center
The air outlet setting of air-conditioning is on the ceiling and air opening end is equipped with grid-like air diffuser, but the wind produced by boasting so still compares
Compared with concentration, adjust indoor temperature uneven, heat exchanger effectiveness is low.
Summary of the invention
Therefore, the utility model is exactly made in view of problem above, and the purpose of this utility model is to provide one kind
Negative pressure suction airflow circular form air outlet structure can effective raising heat exchanging efficiency.The utility model is real by the following technical programs
Existing above-mentioned purpose.
The utility model provides a kind of airflow circulating type diffuser design, comprising: blast pipe, inner sleeve, pod.
The blast pipe is cylindrical body hollow pipe, and 4 fixinig plates are provided at top inner wall, are arranged at the outer wall of its underpart
There are 4 support chips, installation limit film is provided with above the outer wall support piece of blast pipe lower part, installing limit film apart from support chip has one
Set a distance, limit film is located at below ceiling when installation.
Inner sleeve setting is being fixed at air inlet tube cavity by fixinig plate and blast pipe is coaxial, inner sleeve top
Diameter is less than base diameter, and inner sleeve pipe outer wall maximum gauge is less than blast pipe intracavity diameter, inner sleeve top and blast pipe top
It flushes, inner sleeve bottom of the tube slightly projects into bottom duct.
The pod is connected to below blast pipe by support chip, and it is straight that the intracavity diameter of pod is greater than air inlet pipe outer wall
Diameter.
The beneficial effects of the utility model are as follows:
The utility model plays the effect of air multiplication by the nested designs of blast pipe, forms good circulating air
Stream, accelerates the heat exchanger effectiveness of room air, reaches good refrigeration or heating effect.
Detailed description of the invention
A kind of airflow circulating type diffuser design main view of Fig. 1.
A kind of airflow circulating type diffuser design cross-sectional view of Fig. 2.
Specific embodiment
Principle and structure in order to further illustrate the present invention carry out the preferred embodiment of the present invention now in conjunction with attached drawing detailed
It describes in detail bright.
As Figure 1-Figure 2, a kind of airflow circulating type diffuser design, comprising: blast pipe 100, inner sleeve 200, water conservancy diversion
Cover 300.
The blast pipe 100 is cylindrical body hollow pipe, is provided with 4 fixinig plates 101, its underpart outer wall at top inner wall
Place is provided with 4 support chips 102, and installation limit film 103, installation limit are provided with above 100 lower part outer wall support piece 102 of blast pipe
Bit slice 103 has a certain distance apart from support chip 102, and limit film 103 is located at below ceiling when installation.
The setting of inner sleeve 200 is being fixed at 100 inner cavity of blast pipe and blast pipe 100 together by fixinig plate 101
Axis, 200 top diameter of inner sleeve are less than base diameter, and 200 outer wall maximum gauge of inner sleeve is less than 100 intracavity diameter of blast pipe,
The top of inner sleeve 200 with flushed at the top of blast pipe 100,200 bottom of inner sleeve slightly protrudes 100 bottom of blast pipe.
The pod 300 is connected to 100 lower section of blast pipe by support chip 102, and the intracavity diameter of pod 300 is greater than
100 outer diameter of blast pipe.
Working principle of the utility model is:
The cold wind or hot wind that central air-conditioning generates enter blast pipe 100, form two air ducts, are inner sleeve 200 together
Inner cavity air duct is the annular passage that the outer wall of inner sleeve 200 and the inner wall of blast pipe 100 are formed together, since inner sleeve 200 pushes up
Portion's diameter is less than base diameter, cause the inner wall formation of the outer wall of inner sleeve 200 and blast pipe 100 annular passage be by greatly to
Small variation improves the air-flow velocity in annular passage, slightly prominent 100 this part of bottom of blast pipe in 200 bottom of inner sleeve
Negative pressuren zone is formed between 300 upper inner wall of annular airflow and pod, negative pressuren zone top room air is introduced into, and formation follows
Ring air-flow accelerates the heat exchanger effectiveness of room air, reaches good refrigeration or heating effect.
