Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchange devices, in particular to a heat exchange structure for an air compressor. Background Art

[0002] An air compressor compresses air and uses the compressed air to power the device. Air compressors generate a significant amount of heat during operation. To ensure rapid heat dissipation, existing technologies employ specialized cooling devices for heat exchange. For example, a heat exchangeable air compressor, disclosed in Publication No. CN202520521U, utilizes a tubular heat exchanger to cool the oil.

[0003] During use of the existing heat exchange device of the air compressor, the applicant found that: the above-mentioned tubular heat exchange uses continuously curved heat exchange tubes to exchange heat with cooling water. In order to ensure sufficient heat exchange of the air compressor oil, a large number of S-bends are generally provided, thereby increasing the residence time of the oil in the cooling water. This results in a large equipment volume of the entire heat exchanger, which takes up space in the later stage. At the same time, simply using the heat exchange tubes to contact with water, the oil flows in the tubes for heat exchange, and the unit oil-water contact heat exchange area is limited, resulting in low heat exchange efficiency. In order to solve the above-mentioned problems, a heat exchange structure for an air compressor is proposed. Utility Model Content

[0004] The purpose of the present utility model is to provide a heat exchange structure for an air compressor in order to solve the above-mentioned problems.

[0005] The technical solution adopted by the present invention is as follows: a heat exchange structure for an air compressor, including a heat exchange box, a U-shaped heat exchange tube is arranged inside the heat exchange box, both ends of the U-shaped heat exchange tube are installed through the top of the heat exchange box, and a number of heat-conducting fins are provided on the outer walls of both sides of the U-shaped heat exchange tube. A partition is fixedly connected to the middle of the inner cavity of the heat exchange box, the U-shaped heat exchange tube passes through the partition, and a water outlet is provided on the upper part of the partition.

[0006] In a preferred embodiment, the liquid inlet end of the U-shaped heat exchange tube is connected to an oil inlet pipe drawn from an air compressor, and the liquid outlet end of the U-shaped heat exchange tube is connected to an oil outlet pipe returning to the air compressor.

[0007] In a preferred embodiment, a water inlet pipe is connected to one side of the lower portion of the heat exchange box.

[0008] In a preferred embodiment, the other side of the lower portion of the heat exchange box is connected to a water outlet pipe.

[0009] In a preferred embodiment, water flow holes are provided on the heat conducting fins.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0011] 1. In the present invention, the partition divides the heat exchange box into a U-shaped flow, thereby increasing the residence time of the hot water in the heat exchange box. At the same time, the U-shaped heat exchange tube can increase the residence time of the compressed air engine oil in the heat exchange box, and the use of heat-conducting fins can improve the heat exchange efficiency of the U-shaped heat exchange tube. The entire structure can effectively improve the heat exchange efficiency of the compressor oil. Moreover, this structure can fully exchange heat for the oil in the shorter U-shaped heat exchange tube, avoiding the need to set a longer heat exchange tube for sufficient heat dissipation, thereby making the heat exchange equipment more compact and efficient.

[0016] To make the purpose, 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 embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0017] The following will be combined Figure 1-Figure 3 A heat exchange structure for an air compressor according to an embodiment of the present utility model is described in detail.

[0018] Example:

[0019] The present invention provides a heat exchange structure for an air compressor, Figure 1 and Figure 2 As shown, it includes a heat exchange box 1, one side of the lower part of the heat exchange box 1 is connected to a water inlet pipe 8, and the other side of the lower part of the heat exchange box 1 is connected to a water outlet pipe 9. This structure uses the water inlet pipe 8 to introduce the heated water into the heat exchange box 1, and then the heat-exchanged water is discharged from the water outlet pipe 9.

[0020] refer to Figure 1 and Figure 2 As shown, a U-shaped heat exchange tube 2 is provided inside the heat exchange box 1. Both ends of the U-shaped heat exchange tube 2 are installed through the top of the heat exchange box 1. The liquid inlet end of the U-shaped heat exchange tube 2 is connected to the oil inlet pipe 6 led from the air compressor, and the liquid outlet end of the U-shaped heat exchange tube 2 is connected to the oil outlet pipe 7 that flows back to the air compressor. This structure of the oil inlet pipe 6 introduces the oil of the air compressor into the U-shaped heat exchange tube 2, and the U-shaped heat exchange tube 2 is used to exchange heat with the cooling water in the heat exchange box 1. The U-shaped structure design increases the residence time of the oil in the heat exchange box 1, so that the oil can fully dissipate heat. The cooled oil will be sent back to the air compressor through the oil outlet pipe 7.

[0021] refer to Figure 2 and Figure 3 As shown, a plurality of heat-conducting fins 3 are provided on the outer walls of both sides of the U-shaped heat exchange tube 2. This structure utilizes the heat-conducting fins 3 to expand the heat exchange area of ​​the U-shaped heat exchange tube 2, thereby improving the heat exchange efficiency of the oil. Therefore, the oil can be fully heat-exchanged in the shorter U-shaped heat exchange tube 2, avoiding the need to set up a longer heat exchange tube 2 for sufficient heat dissipation, thereby making the heat exchange equipment more compact and efficient.

[0022] refer to Figure 3 As shown, water flow holes 10 are opened on the heat-conducting fins 3. This structure uses the water flow holes 10 to facilitate the rapid flow of water and avoid the heat-conducting fins 3 causing water flow blockage.

[0023] refer to Figure 3 As shown, a partition 4 is fixedly connected to the middle of the inner cavity of the heat exchange box 1, and the U-shaped heat exchange tube 2 passes through the partition 4. A water outlet 5 is provided on the upper part of the partition 4. This structure uses the partition 4 to divide the heat exchange box 1 into a U-shaped flow channel, thereby increasing the residence time of the hot water in the heat exchange box 1, thereby ensuring sufficient heat exchange and cooling of the oil.

[0024] It should be noted that the heat exchange device in the above embodiment is applied to cooling and heat exchange of compressed air machines.

[0025] The implementation principle of a heat exchange structure for an air compressor in an embodiment of the present application is as follows: when in use, the water exchange water is introduced into the heat exchange box 1 by using the water inlet pipe 8, and the partition 4 divides the heat exchange box 1 into a U-shaped flow channel, thereby increasing the residence time of the water exchange water in the heat exchange box 1. When the water exchange water is flowing, the oil inlet pipe 6 introduces the oil of the air compressor into the U-shaped heat exchange tube 2. At this time, the U-shaped heat exchange tube 2 exchanges heat with the water exchange water, and the heat-conducting fins 3 are used to increase the heat exchange, thereby improving the heat exchange efficiency. The water after heat exchange is discharged from the water outlet pipe 9, and the cooled oil will flow back to the compressed air machine from the oil outlet pipe 7, thereby completing the heat exchange cooling of the compressed air machine oil.
