Description

Technical Field

[0001] This application relates to the field of heat exchanger technology, and more particularly to a heat exchange device for cooling water and chilled water heat exchange. Background Technology

[0002] A heat exchanger is a device that allows heat transfer between two or more fluids (liquid or gas) without mixing. Its core function is to cool hot fluids and heat cold fluids. The fluids involved in the heat exchange are physically separated and do not mix.

[0003] However, in an existing heat exchange device for cooling water and chilled water, impurities accumulate inside due to prolonged liquid flow. This necessitates regular cleaning or replacement of the internal components. The inconvenience of disassembly hinders the cleaning process, and the inlet also requires filtration to prevent the accumulation of impurities, which would negatively impact the device's efficiency. Utility Model Content

[0004] In view of the above problems, this application provides a heat exchange device for cooling water and chilled water heat exchange to solve the problems of existing heat exchange devices for cooling water and chilled water heat exchange, where impurities are carried into the internal structure due to long-term liquid flow, requiring regular cleaning or replacement. The inconvenience of disassembly affects the cleaning work, and the inlet also needs to be filtered to prevent a large amount of impurities from entering and accumulating, thereby affecting the internal working efficiency.

[0005] This application provides a heat exchange device for cooling water and chilled water heat exchange. It includes a heat exchange body with mounting grooves on both sides. Bolts are symmetrically and movably fitted onto the outer wall of the heat exchange body. A movable block is threaded onto one side of each bolt. Rotating shafts are symmetrically mounted on both sides of each movable block. Movable strips are hinged to the outer walls of each rotating shaft. The movable strips are arc-shaped and are hinged to one side of an internal groove in the heat exchange body. A clamping plate is hinged to one side of the movable strip and movably fitted into the internal groove in the heat exchange body. A mounting ring is movably fitted inside the mounting groove, and a mounting plate is fixedly mounted on one side of the mounting ring.

[0006] The above method involves inserting the mounting ring on one side of the mounting plate into the mounting groove. Tightening the bolt causes the movable block to move threadedly on one side of the bolt, thereby moving the rotating shaft. The rotating shaft slides in the through groove, which in turn moves the movable strip. The movable strip then rotates around the hinge point installed in the internal groove on one side of the heat exchanger body, moving the clamping plates. This causes the clamping plates on all four sides to limit and clamp the embedded mounting ring, thus fixing the mounting ring in the mounting groove and improving the firmness of the clamping installation. Tightening makes installation more convenient and also makes subsequent disassembly more convenient, facilitating internal cleaning and replacement.

[0007] In some embodiments, a through groove is provided on one side of the movable strip, and the rotating shaft is movably sleeved inside the through groove.

[0008] With the above scheme, when the movable bar is driven, it will rotate around the hinge point installed in the inner groove on one side of the heat exchange body, so that the rotating shaft slides in the through groove, and the through groove provides rotation space for the movable bar.

[0009] In some embodiments, a sealing ring is fixedly installed on one side of the heat exchange body.

[0010] The above solution uses a sealing ring to seal the connection between the heat exchanger and the mounting plate, preventing leakage due to prolonged use.

[0011] In some embodiments, the heat exchange body is provided with a water inlet at its top, a fixing ring is provided on the inner wall of the water inlet, an installation frame is provided on the top of the fixing ring, and a filter screen is provided on the inner wall of the installation frame.

[0012] With the above solution, the mounting frame is fixed to the fixing ring by the four-sided clips, thus fixing the filter screen to the inner wall of the water inlet. The filter screen filters the water entering the water inlet, preventing impurities in the water from entering the heat exchange unit. Long-term use will cause impurities to accumulate, which will affect the efficiency of the heat exchange unit.

[0013] In some embodiments, symmetrical limiting grooves are formed on the inner wall of the water inlet, a movable rod is movably sleeved inside the limiting groove, a locking block is fixedly installed on one side of the movable rod, one side of the locking block is arc-shaped and movably sleeved inside the limiting groove, a telescopic spring is fixedly installed on one side of the locking block, the telescopic spring is movably sleeved on the outer wall of the movable rod, and the locking block is set at the top of the mounting frame.

[0014] The above solution involves pushing the mounting frame to move the locking blocks and movable rods into the limiting groove, thereby causing the telescopic spring to retract. Once the mounting frame is placed on the fixed ring, the telescopic spring's elasticity pushes the locking blocks and movable rods to reset. The mounting frame is then fixed to the fixed ring by the locking blocks on all four sides. Pressing the locking blocks, which are arc-shaped on one side, makes the installation and removal of the mounting frame more convenient.

[0015] In some embodiments, a regulating valve is installed on the outer wall of the water inlet, and the regulating valve is located at the bottom of the mounting frame.

[0016] The above solution allows for the control of the water inlet speed through the regulating valve, which reduces scale buildup.

[0017] The beneficial effects of this utility model are as follows: 1. By tightening the bolt, the movable block moves along the thread on one side of the bolt, thereby driving the rotating shaft to move. The rotating shaft slides in the through groove, which in turn drives the movable strip to move. The movable strip then rotates around the hinge point installed in the inner groove on one side of the heat exchange body, which in turn drives the clamping plates to move. This causes the clamping plates on all four sides to limit and clamp the mounting ring, thus fixing the mounting ring in the mounting groove and improving the firmness of the clamping installation. Tightening makes installation more convenient and also makes subsequent disassembly more convenient, facilitating internal cleaning and replacement.

[0018] 2. After fixing the mounting frame to the fixing ring using the four-sided clips, the filter screen is fixed to the inner wall of the water inlet. The filter screen filters the incoming water to prevent impurities in the water from entering the heat exchange unit. Prolonged use will cause impurities to accumulate, which will affect the efficiency of the heat exchange unit.

[0031] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0032] This application provides a heat exchange device for cooling water and chilled water heat exchange. For example... Figures 1-5 As shown, the device includes a heat exchange body 1, with mounting grooves 2 on both sides. Bolts 3 are symmetrically and movably fitted onto the outer wall of the heat exchange body 1. A movable block 4 is threaded onto one side of each bolt 3. Rotating shafts 5 are symmetrically installed on both sides of the movable block 4. A movable strip 6 is hinged to the outer wall of the rotating shaft 5. The movable strip 6 is arc-shaped and is hinged to one side of the movable strip 6 in an internal groove on one side of the heat exchange body 1. A clamping plate 7 is hinged to one side of the movable strip 6 and is movably fitted into an internal groove on one side of the heat exchange body 1. A mounting ring 10 is movably fitted inside the mounting groove 2, and a mounting plate 11 is fixedly installed on one side of the mounting ring 10.

[0033] The mounting ring 10 on one side of the mounting plate 11 is movably embedded into the mounting groove 2. The bolt 3 is then tightened, causing the movable block 4 to move threadedly on one side of the bolt 3, thereby driving the rotating shaft 5 to move. The rotating shaft 5 slides in the through groove 8, which in turn drives the movable strip 6 to move. The movable strip 6 then rotates around the hinge point installed in the inner groove on one side of the heat exchange body 1, which in turn drives the clamping plate 7 to move. This causes the clamping plates 7 on all four sides to limit and clamp the embedded mounting ring 10, thus fixing the mounting ring 10 in the mounting groove 2, improving the firmness of the clamping installation. Tightening makes installation more convenient and also makes subsequent disassembly more convenient, facilitating internal cleaning and replacement.

[0034] In the technical solution of this application embodiment, a through groove 8 is provided on one side of the movable strip 6, and the rotating shaft 5 is movably sleeved inside the through groove 8.

[0035] When the movable bar 6 is driven, it will rotate around the hinge point installed in the inner groove on one side of the heat exchange body 1, so that the rotating shaft 5 slides in the through groove 8, and the through groove 8 provides rotation space for the movable bar 6.

[0036] In the technical solution of this application embodiment, a sealing ring 9 is fixedly installed on one side of the heat exchange body 1.

[0037] The connection between the heat exchange body 1 and the mounting plate 11 is sealed by the sealing ring 9 to prevent leakage due to prolonged use.

[0038] In the technical solution of this application embodiment, the heat exchange body 1 is provided with a water inlet 12 at the top, a fixing ring 14 is provided on the inner wall of the water inlet 12, an installation frame 15 is provided on the top of the fixing ring 14, and a filter screen 16 is provided on the inner wall of the installation frame 15.

[0039] After the mounting frame 15 is fixed to the fixing ring 14 by the four-sided locking blocks 19, the filter screen 16 is fixed to the inner wall of the water inlet 12. The filter screen 16 filters the water entering the water inlet 12 to prevent impurities in the water from entering the heat exchange body 1. Long-term use will cause impurities to accumulate, which will affect the efficiency of the heat exchange body 1.

[0040] In the technical solution of this application embodiment, the inner wall of the water inlet 12 is symmetrically provided with limiting grooves 17, the limiting groove 17 is movably sleeved with a movable rod 18, a locking block 19 is fixedly installed on one side of the movable rod 18, one side of the locking block 19 is set in an arc shape, one side of the locking block 19 is movably sleeved in the limiting groove 17, a telescopic spring 20 is fixedly installed on one side of the locking block 19, the telescopic spring 20 is movably sleeved on the outer wall of the movable rod 18, and the locking block 19 is set at the top of the mounting frame 15.

[0041] By pushing the mounting frame 15 to push the locking block 19, the locking block 19 and the movable rod 18 slide into the limiting groove 17, thereby driving the telescopic spring 20 to retract. When the mounting frame 15 is placed on the fixing ring 14, the telescopic spring 20 pushes the locking block 19 and the movable rod 18 to reset and move. The mounting frame 15 is fixed on the fixing ring 14 by the locking blocks 19 on all four sides. By pressing the locking block 19, the installation and removal of the mounting frame 15 are more convenient because one side of the locking block 19 is arc-shaped.

[0042] In the technical solution of this application embodiment, a regulating valve 13 is installed on the outer wall of the water inlet 12, and the regulating valve 13 is located at the bottom of the mounting frame 15.

[0043] The speed of water entering through the inlet 12 can be controlled by regulating the valve 13, and the flow rate can reduce the accumulation of scale.
