Detailed Description

In the following, an embodiment of the present invention will be described in detail with reference to the drawings, but it should be understood that the scope of the present invention is not limited by the embodiment.

Example 1:

as shown in fig. 1-5, a fan coil surface cooler with good heat exchange effect comprises a fan coil surface cooler body, wherein the fan coil surface cooler body comprises a plurality of rows of copper pipes 11, aluminum fins 12, a pore plate 13, a water outlet collecting head 14, a plurality of copper elbows 15 and a water inlet collecting head 16, a plurality of first branch pipes 161 of the water inlet collecting head 16 are respectively connected with the rightmost row of copper pipes 11, a plurality of second branch pipes 141 of the water outlet collecting head 14 are respectively connected with the leftmost row of copper pipes 11, and the plurality of copper elbows 15 are communicated with the corresponding copper pipes 11 to form a plurality of flow passages for water inlet on the right side and water outlet on the left side.

The horizontal height of the right water inlet copper pipe 11 of each flow passage is lower than that of the left water outlet copper pipe 11 of the flow passage, and each flow passage sequentially rises in the vertical direction, so that the middle part of the flow passage is not turned up and down, drainage is facilitated, and the flow passage is discharged completely as much as possible.

An exhaust valve 17 is arranged at the highest point of the water outlet and collecting head 14.

The lowest point of the water inlet collecting head 16 is provided with a drainage assembly 18.

The working principle is as follows: the utility model discloses regard as main explanation object (shown in fig. 5) with 6 into 6 out surface cooler pipeline processes, it is to be explained that fig. 6, fig. 7 are the commonly used flow configuration of this series of units equally, and the principle is the same. It is characterized in that:

1. when the water is fed into the surface cooler from one side to the other side in the horizontal direction, namely when the water is fed into the surface cooler in the horizontal direction, the flow of a circulating water pipeline is reverse to the wind direction of a fan, taking the water inlet temperature of 7 ℃ and the water outlet temperature of 12 ℃ as examples, and the air supply temperature of 27 ℃ as an example, in the scheme, the air is firstly subjected to heat exchange with the water at the temperature of 12 ℃ and is finally subjected to heat exchange with the water at the temperature of 7 ℃ and then blown out of a heat exchanger, so that the whole heat exchange effect is better; as shown in fig. 8, when the heat exchanger in the conventional method supplies air, the upper part exchanges heat with water at 12 ℃, and the lower part exchanges heat with water at 7 ℃, so that the heat exchange effect is poor, and the heat exchange efficiency is reduced.

In fig. 7, the water inlet is right-side inlet and left-side outlet, and the fan should be arranged on the left side of the surface air cooler to blow to the right side. Therefore, the process surface cooler needs to be manufactured in a left-right mode, the figure shows the surface cooler used by the left fan coil, and the process of the surface cooler used by the right fan coil is in a left-right mirror image relation with the figure;

2. seen from the vertical direction, every flow of surface cooler is from upwards supplying water down, guarantees that the air in the pipeline can flow to the flow direction and exceed under the drive of rivers, discharges through outlet valve 17 of play water collecting head 14, guarantees that the inside water supply of surface cooler is covered with the pipeline, and no air. Meanwhile, when water needs to be drained, water in each flow pipeline can flow to the bottom completely under the action of self gravity.

3. Every flow path all is from bottom to top and upwind in this patent, and the surface cooler fin hole has the condition of not wearing the copper pipe, and 3 kinds of conditions that fig. 5, 6 and 7 show all have 2 holes and do not wear the copper pipe.

4. Because of the different circumstances of cycle number of pipeline process existence, for guaranteeing better heat exchange efficiency, arrange the inlet channel of less cycle number in surface cooler top position, the flow length of intaking 1 compares other flow length short promptly.

The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the above embodiments, and any changes that can be considered by those skilled in the art shall fall within the protection scope of the present invention.
