Description

Technical Field

[0001] This utility model relates to the field of high-efficiency heat exchanger technology, specifically to a high-efficiency heat exchanger for machine tool chillers. Background Technology

[0002] A high-efficiency heat exchanger is a device that quickly and efficiently transfers heat from one fluid to another. The high-efficiency heat exchanger used in machine tool chillers is used to cool the cooling water used to cool cutting tools.

[0003] Machine tool chillers cool the heat generated by the cutting blade by drawing out cooling water and injecting it into the cutting area. High-efficiency water heaters, on the other hand, cool the water after it has absorbed heat. A high-efficiency heat exchanger consists of a shell, heat-conducting plates, and sealing gaskets. The heat-conducting plates have channels at both ends for liquid flow. During assembly, multiple sets of heat-conducting plates are inserted sequentially into the shell, with a sealing gasket ring-shaped on each plate. After the heat-conducting plates are arranged in an array, the slots at both ends connect to form a liquid channel. Coolant that has absorbed heat is then injected through the inlet at one end of the heat-conducting plate, allowing it to flow within the plate. Conversely, low-temperature cooling water is injected through the inlet at the other end of the heat-conducting plate, flowing into the channel at the other end. The heat-conducting plates absorb the heat carried by the cooling water, which is then conducted to the other end and absorbed by the cooling water there, thus achieving heat exchange.

[0004] In traditional high-efficiency heat exchangers for machine tool cooling water, the gaskets installed on the heat-conducting fins are prone to softening and aging over time, leading to coolant leakage during flow. Coolant leakage can affect heat exchange efficiency. Replacing the gasket at the leak point requires troubleshooting. Since the heat exchange fins are installed in multiple arrays, the troubleshooting work is relatively cumbersome. Furthermore, after finding the leak, replacing the gasket requires removing all the heat exchange fins in front of the leak point and then reinstalling them one by one. Therefore, the maintenance of high-efficiency heat exchangers is quite complicated. Utility Model Content

[0005] The purpose of this utility model is to provide a high-efficiency heat exchanger for machine tool chillers, which solves the problems of existing high-efficiency heat exchangers for machine tool chillers being prone to leakage due to the aging of the sealing gaskets, thus affecting the heat exchange effect, and the cumbersome and time-consuming maintenance procedures, resulting in inconvenience in maintenance.

[0006] This utility model provides the following technical solution: a high-efficiency heat exchanger for machine tool chillers, including a shell, heat exchange components are fixedly connected to both ends of the shell, and the heat exchange components include clamping plates fixedly connected to the inner sides of both ends of the shell, and heat-conducting plates are sleeved on the outer side of the clamping plates.

[0007] The above technical solution utilizes a heat-conducting plate to exchange heat between the liquid flowing in the first and second water channels at both ends.

[0008] As a preferred embodiment of the above technical solution, a first water channel is inserted at one end of the heat-conducting plate, and a second water channel is inserted inside the end of the heat-conducting plate away from the first water channel, wherein the first water channel and the second water channel are configured to be convex.

[0009] The above technical solution involves setting the first and second water channels to be convex, which increases the contact area with the heat-conducting plate and thus improves the heat exchange efficiency.

[0010] As a preferred embodiment of the above technical solution, a first inlet is fixedly connected to one end of the first waterway, and a first outlet is fixedly connected to the end of the first waterway away from the first inlet; a second inlet is fixedly connected to the end of the second waterway near the first outlet, and a second outlet is fixedly connected to the end of the second waterway away from the second inlet.

[0011] By employing the above technical solution, and by positioning the liquid injected into the first inlet and the first outlet at both ends, and the second inlet and the second outlet at different locations, the cooling water and coolant can flow relative to each other, thereby improving heat exchange efficiency.

[0012] As a preferred embodiment of the above technical solution, the ends of the first and second water channels away from the outer shell are fitted with cover plates, and the two ends of the cover plates are fixedly connected with insert plates, with the ends of the insert plates away from the cover plates inserted into the outer shell.

[0013] The above technical solution uses a cover plate and a insert plate to initially restrict the positioning of the first and second waterways.

[0014] As a preferred embodiment of the above technical solution, a spring is fixedly connected inside the insert plate, and a locking block is fixedly connected to the upper end of the spring, with the upper end of the locking block inserted into the outer shell.

[0015] The above technical solution utilizes the elastic potential energy of the spring to push the card block out and insert it into the outer casing to lock and fix the insert plate in place.

[0016] As a preferred embodiment of the above technical solution, a push block is attached to the upper end of the card block, and a rubber pad is fixedly connected to the upper end of the push block, while the lower end of the rubber pad is fixedly connected to the outer shell.

[0017] Through the above technical solution, pressing the rubber pad can push the pusher block to push the card block out of the outer shell.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This is a high-efficiency heat exchanger for machine tool chillers. The heat exchange components can reduce coolant leakage caused by gaskets, and at the same time, it is easy to quickly remove and replace the heat exchanger, thereby improving inspection and maintenance efficiency.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] like Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a high-efficiency heat exchanger for machine tool chillers, including a shell 1, with heat exchange components 2 fixedly connected to both ends of the shell 1, and the heat exchange components 2 including a clamping plate 21 fixedly connected to the inner side of both ends of the shell 1, and a heat-conducting plate 22 sleeved on the outer side of the clamping plate 21. The heat exchange components 2 can reduce coolant leakage caused by the sealing gasket, and at the same time facilitate the quick disassembly and replacement of the heat exchanger, thereby improving the efficiency of inspection and maintenance.

[0028] like Figure 2 and Figure 4As shown, a first water channel 23 is inserted into one end of the heat-conducting plate 22, and a second water channel 24 is inserted into the end of the heat-conducting plate 22 away from the first water channel 23. The first water channel 23 and the second water channel 24 are convex. The first water channel 23 and the second water channel 24 allow cooling water and coolant to flow, thereby exchanging heat through the contact between the first water channel 23 and the second water channel 24 and the heat-conducting plate 22.

[0029] like Figure 2 As shown, a first water channel 23 is fixedly connected to a first water inlet 25 at one end, and a first water outlet 26 is fixedly connected to the end of the first water channel 23 away from the first water inlet 25. A second water channel 24 is fixedly connected to a second water inlet 27 at the end near the first water outlet 26, and a second water outlet 28 is fixedly connected to the end of the second water channel 24 away from the second water inlet 27. Cooling water and coolant can be injected into the first water channel 23 and the second water channel 24 through the first water inlet 25 and the second water inlet 27, and the cooled water and coolant after heat exchange can be discharged through the first water outlet 26 and the second water outlet 28.

[0030] like Figure 5 As shown, the first waterway 23 and the second waterway 24 are attached to a cover plate 29 at the ends away from the outer casing 1, and the two ends of the cover plate 29 are fixedly connected to insert plates 210. The end of the insert plate 210 away from the cover plate 29 is inserted into the outer casing 1, and the first waterway 23 and the second waterway 24 are blocked and restricted by the cover plate 29.

[0031] like Figure 5 As shown, a spring 211 is fixedly connected inside the insert plate 210, and a locking block 212 is fixedly connected to the upper end of the spring 211. The upper end of the locking block 212 is inserted into the outer shell 1. When the insert plate 210 is inserted into the outer shell 1, the outer shell 1 squeezes the locking block 212. After being squeezed, the locking block 212 is inserted into the insert plate 210 to compress the spring 211, so that the elastic potential energy of the spring 211 can be used to push the locking block 212 out and insert it into the outer shell 1 to lock and fix the insert plate 210.

[0032] like Figure 5 As shown, a push block 213 is attached to the upper end of the locking block 212, and a rubber pad 214 is fixedly connected to the upper end of the push block 213. The lower end of the rubber pad 214 is fixedly connected to the outer shell 1. Pressing the rubber pad 214 can push the push block 213 to move, thereby allowing the push block 213 to push the locking block 212 out of the outer shell 1.

[0033] Working principle: When using a high-efficiency heat exchanger to exchange heat with the machine tool cooling water, the cooling water that has absorbed heat in the chiller is injected into the first water channel 23 through the first inlet 25, while the coolant is injected into the second water channel 24 through the second inlet 27. The cooling water and coolant flow relative to each other. When the cooling water and coolant flow in the first water channel 23 and the second water channel 24, the heat carried by the cooling water is absorbed by the heat conduction plate 22 and transferred to the coolant in the second water channel 24, thereby achieving heat exchange. The cooled water after heat exchange is discharged through the first outlet 26, while the coolant after absorbing heat is discharged from the second outlet 28. When repairing or replacing the internal parts of the high-efficiency heat exchanger, the four sets of rubber pads 214 at one end of the outer shell 1 are pressed simultaneously. After the rubber pads 214 are pressed, they squeeze the push block 213. After the push block 213 is pushed, it squeezes the locking block 212, thereby pushing the locking block 212 out of the outer shell 1. After the locking block 212 is pushed, it is inserted into the insert plate 210 to compress the spring. 211. Then, pull the cover plate 29 to pull out the insert plates 210 at both ends of the outer casing 1. Then, pull out the cover plate 29 at the other end of the outer casing 1 according to the above operation. Then, pull the first water channel 23 and the second water channel 24 at both ends to pull out the heat conduction plate 22. Then, with the assistance of the clamping plate 21, pull out the heat conduction plate 22 to completely remove and replace the damaged parts. After replacement, first insert the heat conduction plate 22 into the outer casing 1 with the assistance of the clamping plate 21, and then sequentially insert the first water channel 23 into the outer casing 1. 23 and the second water channel 24 are inserted into the heat-conducting plate 22 for locking. Then, the cover plate 29 drives multiple sets of insert plates 210 to be inserted into the outer shell 1. During the insertion process, the outer shell 1 squeezes the locking block 212. After being squeezed, the locking block 212 is inserted into the insert plate 210 and compresses the spring 211. When the insert plate 210 is inserted, the elastic potential energy of the spring 211 pushes the locking block 212 out to insert it into the outer shell 1 to lock the insert plate 210.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
