Air cooling system

Abstract

Compared to conventional cooling devices that use refrigerants, which are complex and heavy, this cooling device has fewer parts, is lightweight and compact, and yet can instantly produce cool air when connected to a motor. [Solution] As the degree of narrowing of the primary intake port (IP1) and the rotational speed increase, the intense negative pressure atmosphere created by the limited amount of air taken in lowers the temperature of the device itself. Subsequently, once the partition block (5) crosses the secondary intake start point (L), the air drawn into the negative pressure atmosphere from the intake port (IP2) is further cooled as it rapidly flows in, absorbing the heat of vaporization from the space. This air is then discharged from the discharge port, rotating the axis of the rotor of the device into which the partition block (5) is fitted, and continuously discharging cold air that is colder than the air taken into the device.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The present invention does not use a refrigerant gas, and since the entire process of the cooling device is a cooling process, there is no leakage or discharge of the refrigerant gas into the atmosphere due to the use of the refrigerant, and the discharge of the exchanged heat into the atmosphere can be eliminated. At the same time, since the refrigerant gas circulation system becomes unnecessary, the cooling device can be made lightweight and compact, contributing to the issues of global warming and the conservation of copper metal resources.

Means for Solving the Problems

[0006] When the air under atmospheric pressure is stretched in a sealed space to become稀薄 and cooled, the latent heat of vaporization generated in the process of air being inhaled from the hole released to restore the air further cools the air in the negative pressure space.

[0007] It should be noted that the word "稀薄" in the translation of sentence ID=49 is a Chinese character that is not fully translated as there may be no exact equivalent in English. It might be better to use a more descriptive phrase like "become thinner" or "become less dense" depending on the context. Also, the overall translation aims to follow the rules as closely as possible while maintaining the meaning of the original patent text.The base plate (3) combined with the housing (1) has a partition block bearing circumferential groove (13a) provided in a circular orbit uniquely separated from the center (1b) of the housing for the partition block bearing (13) fitted into the partition block to rotate, and a rotor main shaft (4a) hole machined to match the location where the outer circumferential surface (4b) of the rotor fitted with the partition block rotates in close proximity to the lower end (R) of the inner circumferential surface (1a) of the housing. Furthermore, there are two air intake ports, a primary intake port (IP1) and a secondary intake port (IP2), which are opened in specific positions and shapes.

[0008] On the inside of the front cover (2), there is an air outlet (9) with a residual pressure relief recess, a groove identical to the partition block bearing circumferential groove (13a) on the base plate (3), and the rotor's main spindle bearing holder (6a) and rotor's main spindle hole are provided facing the base plate. Therefore, when the rotor assembled inside the front cover rotates counterclockwise, the area around the rotor is machined. Having a claw (4c) The partition block (5), which can fit snugly into the recess, is controlled by a partition block bearing circumferential groove (13a) provided to allow it to rotate while maintaining a state in which its head (5a) is closest to the inner circumferential surface (1a) of the housing. As a result, an airtight spatial region is created between each partition block of this device in which the respective spatial volume changes fluidly.

[0009] The cooling mechanism of this device works as follows: When a fan-shaped partition block (5), designed to withstand operation in a high-pressure environment, passes through the primary air intake (IP1) and the diluted air drawn in rapidly lowers its own temperature, the head (5a) of another partition block that is circulating ahead of the partition block responsible for the negative pressure passes over the secondary air intake start point (L). This causes outside air to be rapidly drawn into the negative-pressure space partitioned by these two partition blocks, absorbing heat through vaporization. This air is further cooled and returns to atmospheric pressure, and is then pushed by the partition block responsible for the negative pressure, passing through the secondary air intake (IP2) equipped with an air check valve before being discharged from the outlet (9). This cooling process is performed continuously for each partition block (5), and the cooling temperature can be further reduced by stacking these devices in series with an air container in between.

[0010] As an alternative application, by keeping the shape of the rotor (4) and partition block (5) of this device the same, and simply changing the position and shape of the holes opening in the base plate (3) and the front cover (2), it can be used as a device for pumping liquids while measuring them. This pumping device has liquid inlet ports (14) located at any position (I~K) within a crescent-shaped region on the base plate side surface where the space becomes negatively pressurized by the counterclockwise rotation of the rotor, which is effective for opening suction holes. As the liquid taken in passes through an airtight spatial region (K~Q) of a specific width provided at the top of the main body to separate the source and destination, the head (5a) of the partition block passing through it fluidly measures the volume of the liquid and pumps it under pressure. From the starting point (Q) of the discharge port onward, a discharge port (15) identical in shape to the liquid intake port (14) provided on the base plate side opens to the front cover (2) side. Furthermore, a liquid pumping device can be made characterized by having a fan-shaped partition block (5) suitable for high-pressure environments as a pump that controls the pumping of the liquid.

[0011] Furthermore, when this device is used for a gas, it can be easily converted into a vacuum pump or a pneumatic compressor simply by appropriately changing the opening position and size of each hole.

Advantages of the Invention

[0012] Compared with the conventional cooling device that uses complex structures and heavy components with a refrigerant, the cooling device of the present invention has fewer parts, is lightweight, and has a compact structure. However, once it is connected to a motor, cold air can be immediately obtained.
