Specific embodiment
The preferred embodiment of the utility model will be described in detail by reference to attached drawing, in this way for belonging to utility model
These embodiments easy to accomplish for people in the existing technical staff in field with ordinary skill.However the utility model can also
It is realized in the form of a variety of different, therefore the utility model is not limited to embodiments described hereinafter.In addition, in order to more clearly
The utility model is described, will be omitted from attached drawing with the component that the utility model is not connect.
As shown in Figure 1, a kind of fan coil with spiral overlapping type coil arrangement, comprising: shell 1, blower 2, water conservancy diversion
Cover 3, heat exchanger 4, drip tray 5；
1 inside of shell is arranged in close to the position of air inlet in the blower 2；
The side of 2 air outlet of blower is arranged in the pod 3；
The heat exchanger 4 is inclined at the end side of pod 3；
The lower end of heat exchanger 4 is arranged in the drip tray 5；
The heat exchanger 4 includes: coil pipe 41, end plate 42, convex thorn 43；
The coil pipe 41 is that the stacked pipe 411 of multiple spirals joins end to end, and is staggered up and down, so that water flow is from coil pipe 41
The stacked pipe 411 of a spiral to flow to the stacked pipe 411 of next spiral be mode from the bottom to top or from top to bottom；
The quantity that the coil pipe 41 is be it is multiple, each coil pipe 41 is fold-back formula pipeline, and coil pipe 41 is existed by setting
The end plate 42 of its two sides is fixed；
The outer surface of the coil pipe 41 is provided with several convex thorns 43.
As shown in Figure 3-4, it is preferred that as an embodiment, between the circle and circle of the stacked pipe 411 of spiral
Spacing it is smaller, enclose the lesser spacing heat that coil pipe 41 is conducted outward between circle and more gather, so that air
It is more abundant by exchanging heat when coil pipe 41.
As shown in Figure 2, it is preferred that as an embodiment, the spiral shell in the air inlet direction and coil pipe 41 of the coil pipe 41
The direction for revolving the axis of the center hole of stacked pipe 411 is consistent, and air is flowed into along this direction, passes through the stacked pipe 411 of spiral
When gap between center hole and coil pipe 41, air collides tube wall and generates turbulent flow, so that air heat exchange is more abundant.
As shown in Figure 5, it is preferred that as an embodiment, convex 43 setting of thorn it is more intensive, this setting makes
Heat exchanger effectiveness of the air stream through coil pipe 41 when is obtained to further increase.
As shown in Figure 2, it is preferred that as an embodiment, the water flow in the coil pipe 41 is flowed into from a point, b point stream
Out, water flow is by coil pipe 41, since coil pipe 41 is that the stacked connection of pipe 411 of multiple spirals is formed, so that the water inside coil pipe 41
Repeatedly changed course occurs for stream, and more fierce collision occurs inside coil pipe 41, causes the generation of turbulent flow for water flow, so that pipe
Interior water flow is more fully mixed, and the in-pipe flow temperature difference reduces, and promotes the heat exchange efficiency of in-pipe flow, while spiral stepped construction
It is arranged so that the contact area of air and coil pipe 41 increases, to promote the heat exchanger effectiveness with air.
Utility model works principle:
Blower 2 works first, and air comes out from pod 3 and flows to heat exchanger 4, flows to out after exchanging heat using heat exchanger 4
Air port.The wherein setting of 41 structure of coil pipe of heat exchanger 4, so that repeatedly changed course occurs for the water flow inside coil pipe 41, water flow is in disk
More fierce collision occurs inside pipe 41, the generation of turbulent flow is caused, so that the water flow in pipe is more fully mixed, in pipe
The water flow temperature difference reduces, and promotes the heat exchange efficiency of in-pipe flow, while the setting of spiral stepped construction is so that air and coil pipe 41
Contact area increases, to promote the heat exchanger effectiveness with air.
