[0002] The main function of the Sanheng fresh air blower is to control the temperature, humidity, and cleanliness of indoor air. It is essentially a liquid temperature and humidity control air conditioner. The main working principle is to pump the heat exchange medium at the bottom of the unit to the top liquid distributor, spray it onto the packing paper below, and then exchange heat with the air to achieve the purpose of temperature and humidity control. Among them, the liquid distributor is used to evenly distribute the heat exchange medium solution. Therefore, designing a liquid distributor that can evenly distribute the liquid is very important to improve the heat exchange efficiency of the Sanheng fresh air blower. Summary of the Invention

[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0015] Example

[0016] like Figure 1 and 2 As shown, a liquid distributor for uniformly distributing liquid includes a main pipe 10 and liquid distribution pipes 11 uniformly distributed along the length direction of the main pipe 10, and the main pipe 10 and the liquid distribution pipes 11 are arranged in the same plane, one end of the liquid distribution pipe 11 is closed and the other end is connected to the main pipe 10, and the bottom of the liquid distribution pipe 11 is provided with liquid distribution holes 12 distributed along the length direction, and the adjacent liquid distribution holes 12 along the length direction on the same liquid distribution pipe 11 have the same hole spacing L, and the hole spacing L here refers to the distance between the centers of the liquid distribution holes 12, and the hole spacing L gradually increases on the liquid distribution pipe 11 according to the flow direction of the liquid in the main pipe 10, that is, the closer to the liquid inlet of the main pipe 10, the smaller the hole spacing L is and the more holes there are.

[0017] In this embodiment, the following specifications of the liquid distributor are selected for flow rate test: Figure 2As shown, the inner diameter of the main pipe 10 is 3 cm, the inner diameter of the liquid distribution pipe 11 is 2.8 cm, there are four liquid distribution pipes 11, the center distance between adjacent liquid distribution pipes 11 is 8 cm, and the hole distances L on the liquid distribution pipes 11 starting from the liquid inlet of the main pipe are 2.1 cm, 2.4 cm, 2.7 cm and 3 cm respectively, which are respectively marked as liquid distribution pipe No. 1 111, liquid distribution pipe No. 2 112, liquid distribution pipe No. 3 113 and liquid distribution pipe No. 4 114. The pipe 114 is provided with two rows of liquid distribution holes 12 arranged towards the center of the liquid distributor. This is to prevent the liquid sprayed in the liquid distributor from being sprayed to other places other than the filler paper, reducing the utilization rate of the heat exchange medium solution, and the two rows of liquid distribution holes 12 are staggered. The second liquid distribution pipe 112 and the third liquid distribution pipe 113 are each provided with three rows of liquid distribution holes 12, and the three rows of liquid distribution holes 12 are staggered. The aperture of all liquid distribution holes 12 is 3mm; the total pipe flow test environment is 1m 3 / h, the total flow rate of each liquid distribution pipe 11 during stable operation is obtained and tabulated in Table 1. The flow rate unit in the table is L / s. It will be understood by those skilled in the art that the arrangement of the liquid distribution holes 12 in this application is a key feature for solving the technical problem, and the inner diameters of the main pipe 10 and the liquid distribution pipe 11 are provided to provide a more comprehensive disclosure and help those skilled in the art understand the present technical solution.

[0019] Table 1

[0020] The data in Table 1 indicates that the total flow rate deviation on each liquid distribution pipe 11 is extremely small, and the overall distribution uniformity is high. This ensures uniform liquid distribution during operation, thereby ensuring that the amount of heat exchange medium solution sprayed onto the packing paper by each liquid distribution pipe 11 does not vary significantly, thus avoiding the problem of excessive or insufficient spraying on a portion of the packing paper. Furthermore, due to the differences in the hole spacing L between different liquid distribution pipes 11, the liquid distribution holes 12 on the liquid distribution pipes 11 farther away from the main pipe liquid inlet are sparser, resulting in fewer corresponding spray points on the packing paper. Therefore, at least two rows of liquid distribution holes are provided on each liquid distribution pipe 11, and the different rows of liquid distribution holes 12 on the same liquid distribution pipe 11 are staggered. This staggered arrangement increases the number of spray points, further improving the liquid distribution uniformity of the liquid distributor.
