Abstract
A new air-conditioning terminal fan-coil unit cooling coil is provided in order to solve the defects of small windward area and large air side resistance of the traditional cooling coil. The utility model is S-shaped and is as high as the prior cooling coil, a twisted tilt angle is 30 degrees and a windward area is twice of the area of the prior cooling coil. Knowing upon the formula Vy=Gt/Fy and delta Pk=0.642 x 40.191 x Vy<1.455> x Xi<0.63>, the larger the windward area Fy is, the smaller the headwind speed Vy is; if the headwind speed Vy is reduced, the wind side resistance is reduced rapidly resulting in delta Pk loss. Thus, the windward area can be enlarged, the headwind speed can be reduced, the windage loss can be decreased and the heat exchange area can be doubled under the condition that the utility model keeps the overall height, so as to promote the heat exchange amount of the unit.
Description
Affiliated technical field
The utility model relates to the surface cooler of extensive use in the air conditioning terminal fan coil units.
Background technology
At present, the surface cooler that is widely used in air conditioning terminal fan coil equipment is mostly taked the rectangular configuration form.Though simple for assembly process, there are shortcomings such as front face area is little, air drag is big.
Summary of the invention
In order to overcome all drawbacks in traditional surface cooler design, the utility model provides a kind of novel surface cooler.This surface cooler has not only increased front face area by changing the technology that is connected of former surface cooler fin shape and pipeline, has reduced windage loss, and has increased heat exchange area, thereby improved the heat exchange amount of unit.
The technical scheme that its technical problem that solves the utility model adopts is: this surface cooler is serpentine, takes height consistent with former surface cooler, and tortuous inclination angle is 30 degree, and front face area is the design concept of two times of former surface coolers.Vy=Gt/Fy learns according to formula: under the certain situation of air quantity Gt, front face area Fy is big more, and Vy is more little for face velocity.According to wet cooling condition air side resistance formula Δ Pk=0.642 * 40.191 * Vy
1.455* ζ
0.63Learn: when analysing wet coefficient ξ when constant, air side resistance Δ Pk becomes the proportional relationship of power side with face velocity Vy, thus face velocity Vy reduce can reduce wind collateral resistance loss Δ Pk rapidly.
The beneficial effects of the utility model are: not only increased front face area, reduced face velocity, reduced windage loss, and heat exchange area increased by one times, thereby improved the heat exchange amount of unit.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is a shaft side figure of the present utility model.
1. fin among the figure, 2. outlet pipe, 3. backplate, 4. water inlet pipe.
The specific embodiment
Serpentine fin (1) is made in punching press, fin (1) is stood up come into line, and two ends add backplate (3), wear the sheet expanded joint, weld water inlet pipe (4) and outlet pipe (2) at last.
Claims (1)
1. the terminal fan coil units surface cooler of an air-conditioning is 30 to spend the fin, backplate, water inlet pipe and the outlet pipe that are serpentine and form by tortuous inclination angle, and it is characterized in that: surface cooler is serpentine.
