Meanwhile, the ventilation and air conditioning units in the open areas of underground concourses primarily function as cooling and dehumidification units during the summer or transitional seasons, while only providing ventilation in winter.

[0003] In existing technologies, such as the Chinese patent application CN217004836U entitled "An Evaporator Bypass Structure with Variable Air Duct," an air filter, an evaporator one, a bypass valve, an evaporator two, and a centrifugal fan are installed within a combined air conditioning unit.

Compared with existing technologies, this invention can automatically start and stop the bypass valve according to the cooling and ventilation modes without increasing the unit size, greatly saving initial investment and improving the energy efficiency of the ventilation and air conditioning unit during all seasons, while reducing operating costs.

[0004] In existing technologies for air conditioning cooling, the different flow rates of the supply and bypass ducts can lead to low accuracy in air temperature control when multiple air delivery methods are used.

[0005] Therefore, it is necessary to provide a bypass structure for a precision air conditioner used in semiconductor temperature control equipment to solve the above-mentioned technical problems. Utility Model Content

[0006] This invention provides a bypass structure for a precision air conditioner used in semiconductor temperature control equipment, which solves the problem that the air temperature control accuracy is low when multiple air delivery processes are performed due to the difference in size and flow rate between the supply air duct and the bypass duct.

[0015] Compared with related technologies, the air duct bypass structure for a precision air conditioner used in semiconductor temperature control equipment provided by this utility model has the following beneficial effects:

[0016] This utility model provides a bypass structure for a precision air conditioner used in semiconductor temperature control equipment. By setting a bypass pipe, when the air conditioner's airflow temperature is adjusted, the control valve is opened and the heater is started, allowing the heater to deliver the higher-temperature airflow to the ventilation duct through the bypass pipe. At this time, the higher-temperature airflow inside the ventilation duct can be evenly mixed with the higher-temperature airflow, thereby achieving the effect of adjusting the airflow temperature delivered by the ventilation duct. This avoids the problem of large temperature adjustment errors caused by a large difference between the airflow flow rate of the ventilation duct and the airflow flow rate of the bypass pipe, thus greatly improving the accuracy of temperature adjustment of the temperature control equipment.

[0017] By setting up a conveying mechanism, when air is being conveyed, the rotary motor is started, which drives the fan blades to rotate rapidly, thereby driving the airflow inside the evaporator to be quickly conveyed into the ventilation duct, thus increasing the airflow conveying speed of the ventilation duct, that is, increasing the air conveying speed.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of a duct bypass structure for a precision air conditioner used in semiconductor temperature control equipment provided by this utility model; Figure 2 for Figure 1 The image shows a front view of a duct bypass structure for a precision air conditioner used in semiconductor temperature control equipment. Figure 3 for Figure 1 The image shows a front view of a ventilation duct in a bypass structure of a precision air conditioner for semiconductor temperature control equipment. Figure 4 for Figure 1 The diagram shows a cross-sectional view of a ventilation sleeve in a duct bypass structure for a precision air conditioner used in semiconductor temperature control equipment. The duct bypass structure includes a base plate 1, an air conditioning unit 2 fixedly mounted on the top of the base plate 1, an evaporator 3 fixedly mounted on the top of the base plate 1, a compressor 4 fixedly mounted on the top of the base plate 1, a ventilation pipe 5 fixedly sleeved on the side of the evaporator 3, a heater 6 fixedly sleeved on the top of the base plate 1, a bypass pipe 7 fixedly sleeved on the side of the heater 6, a control valve 8 fixedly mounted on the outside of the bypass pipe 7, a heat insulation sleeve 9 fixedly sleeved on the outside of the bypass pipe 7, a sealing sleeve 10 fixedly sleeved on one side of the evaporator 3, a ventilation sleeve 11 fixedly sleeved on the other side of the evaporator 3, a conveying mechanism 12 disposed inside the ventilation sleeve 11, a filter screen 13 fixedly sleeved on the side of the ventilation sleeve 11, and a fixing mechanism 14 disposed at the bottom of the base plate 1.

[0025] There are two bypass pipes 7, which are symmetrically distributed about the ventilation pipe 5. By setting the bypass pipes 7, when the temperature of the air conditioning supply air is adjusted, the control valve 8 is opened and the heater 6 is started, so that the heater 6 can deliver the higher temperature air to the ventilation pipe 5 through the bypass pipes 7. At this time, the higher temperature air inside the ventilation pipe 5 can be evenly mixed with the higher temperature air, thereby achieving the effect of adjusting the temperature of the air supply air in the ventilation pipe 5. This avoids the problem of large temperature adjustment error caused by a large difference between the air flow rate of the ventilation pipe 5 and the air flow rate of the bypass pipe 7, thus greatly improving the accuracy of temperature adjustment of the temperature control equipment.

[0026] The front of the ventilation duct 5 is conical, and the material of the ventilation duct 5 is stainless steel. By setting the ventilation duct 5, when airflow is being transported, the ventilation duct 5 can fully collect and transport the exhaust airflow of the evaporator 3, thereby avoiding the problem of low airflow transport efficiency when the size of the evaporator 3 and the ventilation duct 5 are significantly different.

[0027] The insulation sleeve 9 is made of fiberglass and is compatible with the bypass pipe 7. By setting the insulation sleeve 9, the bypass pipe 7 can be insulated when hot air is transported, thus avoiding the problem of rapid heat loss when hot air is transported by the bypass pipe 7, thereby improving the heat transport efficiency of the bypass pipe 7.

[0028] The sealing sleeve 10 is fixedly fitted inside the ventilation pipe 5, and the sealing sleeve 10 is made of rubber. By setting the sealing sleeve 10, when the ventilation pipe 5 is installed and connected, the ventilation pipe 5 is fitted onto the outside of the sealing sleeve 10, so that the sealing sleeve 10 can fill the gap between the ventilation pipe 5 and the evaporator 3, thereby avoiding the problem of air inside the evaporator 3 being discharged through the gap, thus improving the sealing performance of the ventilation pipe 5.

[0029] The conveying mechanism 12 includes a rotary motor 121, which is fixedly installed inside the ventilation sleeve 11, and a fan blade 122 is fixedly sleeved on the output shaft of the rotary motor 121. By setting the conveying mechanism 12, when air is being conveyed, the rotary motor 121 is started, which drives the fan blade 122 to rotate rapidly, thereby driving the airflow inside the evaporator 3 to be quickly guided into the ventilation pipe 5, thereby increasing the air conveying speed of the ventilation pipe 5, that is, increasing the air conveying speed.

[0030] The filter screen 13 is made of synthetic fiber material, and the diameter of the filter screen 13 is the same as the diameter of the ventilation sleeve 11. By setting the filter screen 13, when air is being transported, the filter screen 13 can filter the air entering the evaporator 3, so that dust in the air can be blocked by the filter screen 13 to the outside of the evaporator 3. This avoids the problem of dust accumulating when it enters the evaporator 3 with the air, which would cause dirt inside the evaporator 3, thereby improving the cleanliness of the inside of the evaporator 3.

[0031] The fixing mechanism 14 includes a support frame 141, which is fixedly connected to the bottom of the base plate 1. The support frame 141 has a threaded post 142 threaded inside. By setting the fixing mechanism 14, when the air duct is installed and fixed, the threaded post 142 is rotated to fix the support frame 141 on the workbench or the ground. This allows the support frame 141 to support and fix the base plate 1, thus avoiding corrosion of the base plate 1 when it is in contact with the damp ground for a long time, which could lead to damage to the air conditioning unit 2. This improves the protection effect of the temperature control equipment and the air duct.

[0032] The working principle of the air duct bypass structure for a precision air conditioner used in semiconductor temperature control equipment provided by this utility model is as follows:

[0033] Step 1: First, when adjusting the airflow temperature of the air conditioner, open control valve 8 and start heater 6. This allows heater 6 to deliver higher-temperature airflow to ventilation duct 5 through bypass pipe 7. At this point, the higher-temperature airflow inside ventilation duct 5 is evenly mixed with the higher-temperature airflow, thus achieving the desired temperature adjustment effect. This avoids the problem of large temperature adjustment errors caused by a significant difference between the airflow flow rate of ventilation duct 5 and the airflow flow rate of bypass pipe 7, greatly improving the accuracy of temperature control. During airflow delivery, ventilation duct 5 can comprehensively collect the exhaust airflow from evaporator 3. The bypass pipe 7 is insulated by the heat insulation sleeve 9 during hot air transport, thus avoiding the problem of low air transport efficiency when the size of the evaporator 3 and the ventilation pipe 5 are significantly different. This prevents the rapid heat loss caused by the bypass pipe 7 during hot air transport, thereby improving the heat transport efficiency of the bypass pipe 7. When installing and connecting the ventilation pipe 5, the ventilation pipe 5 is sleeved on the outside of the sealing sleeve 10, so that the sealing sleeve 10 can fill the gap between the ventilation pipe 5 and the evaporator 3, thereby preventing the air inside the evaporator 3 from being discharged through the gap, thus improving the sealing performance of the ventilation pipe 5.

[0034] Step 2: When air is being transported, the rotary motor 121 is started, which drives the fan blades 122 to rotate rapidly. This, in turn, drives the airflow inside the evaporator 3 to be quickly transported into the ventilation duct 5, thereby increasing the air transport speed of the ventilation duct 5, i.e., increasing the air transport speed. During air transport, the filter screen 13 filters the air entering the evaporator 3, blocking dust in the air to the outside of the evaporator 3. This prevents dust from accumulating inside the evaporator 3 when it enters with the air, thus improving the cleanliness of the evaporator 3. When installing and fixing the air duct, the threaded column 142 is rotated, which fixes the support frame 141 on the workbench or ground. This allows the support frame 141 to support and fix the base plate 1, preventing corrosion of the base plate 1 when it is in contact with a damp ground for a long time, which could damage the air conditioning unit 2. This improves the protection effect of the temperature control equipment and the air duct.

[0035] Compared with related technologies, the air duct bypass structure for a precision air conditioner used in semiconductor temperature control equipment provided by this utility model has the following beneficial effects:

[0036] By setting a bypass pipe 7, when the temperature of the air conditioning supply airflow is adjusted, the control valve 8 is opened and the heater 6 is started, so that the heater 6 can deliver the higher temperature airflow to the ventilation pipe 5 through the bypass pipe 7. At this time, the higher temperature airflow inside the ventilation pipe 5 can be evenly mixed with the higher temperature airflow, thereby achieving the effect of adjusting the temperature of the airflow supplied by the ventilation pipe 5. This avoids the problem of large temperature adjustment error caused by a large difference between the airflow flow of the ventilation pipe 5 and the airflow flow of the bypass pipe 7, thus greatly improving the accuracy of temperature adjustment of the temperature control equipment.
