Description

Technical Field

[0001] This invention relates to a hexagonal airflow plate for an intelligent fresh air system, its processing method, and heat exchange core, belonging to the technical field of intelligent fresh air systems. Background Technology

[0002] A fresh air system, also known as an energy-saving intelligent ventilation system for computer rooms, meets the constant temperature and humidity requirements of computer rooms and effectively solves the harm of dust pollution to computer rooms. It is particularly suitable for the energy-saving requirements of communication equipment computer rooms. It achieves system reliability, high efficiency, and low cost. The design concept uses air enthalpy value judgment, which effectively increases the range of external air environment utilization, making the annual working time more than 20% longer than that of systems that control temperature and humidity alone; it is a new design in modern buildings to facilitate the exchange of internal and external air. The core of the system for heat exchange is an important component, and the core of this component is the airflow plate for internal and external air outflow. Existing airflow plate designs are all designed to provide sufficient heat exchange time between internal and external air, and the airflow channels are designed as curved loops. Even to achieve internal bypass flow, there are holes in the partitions. Such designs increase the heat exchange time of the air inside the core, but they also increase wind resistance, and the power of the heat exchange fan must be increased accordingly, which also increases energy consumption and does not meet the current requirements for energy conservation and emission reduction. Summary of the Invention

[0003] To address the high energy consumption issue of existing intelligent fresh air systems, a hexagonal airflow plate for intelligent fresh air systems, its processing method, and heat exchange core are provided. By improving the design of the airflow plate for heat exchange, the energy consumption of the entire system is reduced.

[0004] This invention solves the above-mentioned technical problems through the following technical solution: a hexagonal airflow plate for an intelligent fresh air system, comprising a hexagonal outer frame and partitions within the outer frame, characterized in that the partitions are straight strips, and the partitions are divided into guide partitions and ventilation partitions; the outer frame includes two parallel sides and corner sides on both sides of the parallel sides, with four corner sides, two corner sides forming a group, each group of corner sides forming a right angle, one group of opposite corner sides having air holes, and the other group of opposite corner sides being a closed structure; the guide partitions are closed structures, with air ducts on both sides of the guide partitions, and adjacent air ducts are not connected; the ventilation partitions are intersecting the guide partitions at an included angle, and the ventilation partitions have ventilation holes.

[0005] The advantages of the above technical solution are: it overcomes the common design concept that the air in the core plate of the intelligent ventilation system should be curved in the loop to increase the heat exchange time of the air in the core. By designing the air as a straight channel, and through actual testing, it was found that using the airflow plate of this application not only has no impact on the heat exchange efficiency, but also reduces costs and makes the molds for production and processing easier to open. Moreover, using the airflow plate of this application reduces the wind resistance in the fresh air system, reduces the energy consumption of the entire system, and achieves the same heat exchange effect while reducing the power of the fan used.

[0006]

[0007] The table above shows the results at 200m. 3 / h and 250m 3 At a wind speed of / h, a comparison of the heat recovery rates of the airflow plate structure of this application and the existing airflow plate structure shows that the recovery efficiency is not much different and is basically similar. However, the resistance within the system is significantly lower in the structure of this application than in the existing conventional structure. Therefore, after the airflow plate is made into a heat exchange core, a low-power fan can be used, thereby achieving the purpose of reducing power consumption and saving energy and reducing emissions.

[0008] Based on the above technical solution, the inventors have made the following improvements and enhancements:

[0009] Furthermore, the hexagonal airflow plate is formed by stamping and cutting a perforated plate.

[0010] The beneficial effects of the above-mentioned technical features in this application are: using a perforated plate for processing improves the continuity of production; only the angle between the mold and the perforated plate needs to be controlled to quickly stamp and cut out the desired airflow plate.

[0011] Furthermore, the corners of the closed structure are heat-sealed using an ultrasonic heat-sealing machine.

[0012] The beneficial effects of the above-mentioned technical features in this application are: the perforated plate is directly used for processing, and there will be air holes on many sides of the outer frame. However, in order to ensure the certainty of the air duct, a pair of opposite corner edges need to be in a closed state without air holes. Therefore, heat sealing is used to seal them. The heat sealing efficiency of the ultrasonic heat sealing machine is high, the production speed is fast, and the heat sealing effect is good.

[0013] Furthermore, the angle between the guide strip and the parallel side is 10° to 25°.

[0014] Furthermore, the angle between the guide strip and the parallel side is 20°.

[0015] The beneficial effect of the above-mentioned technical features in this application is that a suitable air duct angle is conducive to heat exchange. Through practical experience and research, this suitable angle has been determined.

[0016] Furthermore, the included angle between the ventilation partition and the guide partition is 60° to 75°.

[0017] The beneficial effects of the above-mentioned technical features in this application are:

[0018] A method for manufacturing a hexagonal airflow plate for an intelligent fresh air system, characterized by the following steps:

[0019] Step 1: Prepare the initial material by stamping the sheet metal. Place the porous sheet metal under the stamping machine and stamp it into a hexagonal frame structure by the stamping die. The cutting blade in the die cuts the parallel sides at an angle of 10° to 25° with the holes of the porous sheet metal. The width of a set of opposite corner sides of the initial material is greater than the width of other sides to leave space for heat sealing.

[0020] Step 2, heat sealing and edge removal: The initial material is placed into the heat sealing device. After positioning, the reserved heat sealing space on the initial material is removed by the ultrasonic heat sealing device, and the hole on the corner edge is sealed to form a hexagonal airflow plate for the intelligent fresh air system.

[0021] The beneficial effects of the above-mentioned technical features in this application are as follows: In the processing of the airflow plate of this design, because ultrasonic heat sealing is required to close a pair of opposite corners, the width of the opposite corners must be larger than the width of the other sides in the initial processing, so as to play a role in identification and also to provide processing allowance for ultrasonic heat sealing. During ultrasonic heat sealing, after the allowance is removed, the heat sealing of the side is achieved.

[0022] A heat exchange core for an intelligent fresh air system is characterized by comprising a hexagonal airflow plate and a diaphragm, wherein the hexagonal airflow plate is the hexagonal airflow plate for an intelligent fresh air system as described in any one of claims 6; the hexagonal airflow plates and diaphragms are alternately arranged, each hexagonal airflow plate has a diaphragm on both sides, and the guide strips of two adjacent hexagonal airflow plates are cross-arranged; the hexagonal airflow plates and diaphragms are alternately composited in multiple layers to form a heat exchange core matrix, and the side surfaces formed by the parallel edges on both sides of the heat exchange core matrix are sealed with an adhesive to form the heat exchange core.

[0023] The beneficial effects of the above technical solution are as follows: the heat exchange core is formed by a diaphragm and a hexagonal airflow plate colloid, and the two adjacent hexagonal airflow plates adopt a cross structure of guide strips to form an air inlet and an air outlet, and the two exchange heat energy in a cross flow; and the internal mixing is prevented by sealing the parallel sides.

[0024] Furthermore, the hexagonal airflow plate is manufactured using the processing method described in claim 7.

[0025] The beneficial effect of the above-mentioned technical features in this application is to improve production efficiency. Attached Figure Description
