Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a heat exchanger with a protective structure. Background Art

[0002] A heat exchanger, also known as a heat exchanger or heat exchange equipment, is a device used for heat exchange. Its operating principle is based on the laws of thermodynamics, which stipulate that heat spontaneously transfers from a high-temperature object to a low-temperature object. In a heat exchanger, when two fluids of different temperatures meet, heat is transferred from the high-temperature fluid to the low-temperature fluid, thereby achieving heat transfer and utilization. Heat exchangers typically rely on three heat transfer methods: convection, conduction, and radiation, but primarily utilize convection and conduction for efficient heat transfer. Convection refers to the exchange of heat through contact and mixing of fluids, while conduction transfers heat through molecules within solid materials. Heat exchangers are used in a variety of fields, including refrigeration and air conditioning, energy production, and chemical processes. The protective structure is a key component of a heat exchanger.

[0003] For example, the Chinese patent "A Heat Exchanger" with the announcement number CN213090574U includes an outer frame, a heat exchange tube is arranged in the outer frame, a water port is arranged on the heat exchange tube, the water port is connected to a pressure gauge, a quick connector is detachably connected between the pressure gauge and the water port, the quick connector includes an external threaded tube and an internal threaded tube, either end of the external threaded tube is fixedly connected to the pressure gauge, the internal threaded tube is fixedly connected to the water port, and the external threaded tube is threadedly connected to the internal threaded tube, a control valve is arranged between the internal threaded tube and the water port, a sealing strip is arranged at the connection between the external threaded tube and the internal threaded tube, and the external threaded tube is fixedly connected to the internal threaded tube. An embedding groove is provided on the corrugated tube, and the sealing strip is embedded in the groove. A closing sleeve is provided at the connection between the external threaded tube and the internal threaded tube, and the closing sleeve is threadedly connected to the outer wall of the internal threaded tube. Heat exchange fins are provided on both sides of the width direction of the outer frame. Any heat exchange tube is welded to the adjacent heat exchange tubes to form a welding node. A leak-proof component is provided at the welding node, and the leak-proof component includes a sealing gasket and a clamp. The sealing gasket is wound at the welding node. Two clamps are provided at intervals around the axis of the heat exchange tube. The clamp holds the sealing gasket tightly, and the two clamps are provided at the welding node and fixed by bolts.

[0004] Although the above-mentioned existing technology can realize the use of the heat exchanger, in actual use, on the one hand, dust in the air is easy to adhere to the surface of the heat exchanger's fins. During the use of the heat exchanger, the dust in the air directly contacts the heat exchanger fins, causing the dust to adhere to the surface of the heat exchanger fins, forming a thick dust layer, thereby reducing the heat exchange efficiency of the heat exchanger fins. On the other hand, after the heat exchanger is fixed, it is difficult to buffer the vibrations generated by other mechanical operations. After the heat exchanger is installed, the vibrations generated by other mechanical operations will be directly transmitted to the heat exchanger, causing the vibrations to interfere with the fluid flow inside the heat exchanger, thereby reducing the heat exchange efficiency. Therefore, it does not meet the existing needs. In this regard, we propose a heat exchanger with a protective structure. Utility Model Content

[0005] The purpose of the present utility model is to provide a heat exchanger with a protective structure to solve the problems raised in the above background technology that dust in the air easily adheres to the surface of the heat exchanger's fins, and that the heat exchanger is difficult to buffer the vibrations generated by other mechanical operations after being fixed.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a heat exchanger with a protective structure, including two mounting plates, a first filter plate is provided in the grooves on the upper and lower ends of the mounting plate, and a second filter plate is provided in the grooves on the front and rear ends of the mounting plate, and a filter screen is fixedly provided at the middle position inside the first filter plate and the second filter plate, and the filter screen is a through-type structure.

[0007] Preferably, two first threaded holes are provided inside the upper and lower grooves of the mounting plate, and first bolts are provided at the four corners of one end of the first filter plate close to the outer side of the mounting plate, and one end of the first bolt extends into the inside of the first threaded hole.

[0008] Preferably, two second threaded holes are provided inside the front and rear end grooves of the mounting plate, and second bolts are provided at the four corners of one end of the second filter plate close to the outer side of the mounting plate, and one end of the second bolt extends into the inside of the second threaded hole.

[0009] Preferably, magnetic strips are fixedly provided on both sides of one end of the first filter plate and the second filter plate close to the inner side of the mounting plate and on the surface of the mounting plate groove, and the magnetic strips on the first filter plate and the second filter plate correspond to the positions of the magnetic strips on the mounting plate.

[0010] Preferably, a fixing seat is fixedly provided at the front and rear ends below one side of the mounting plate, a through hole is provided inside the fixing seat, a rubber pad is provided at the lower end of the fixing seat, and the rubber pad is connected to the fixing seat by glue.

[0011] Preferably, a circulation pipe is provided in the middle position between the mounting plates on both sides, and the circulation pipe is distributed alternately in a bent manner. A plurality of heat dissipating fins are provided on the outside of the circulation pipe located between the mounting plates, and the heat dissipating fins are distributed equidistantly, and the heat dissipating fins are welded and fixed to the circulation pipe.

[0012] Preferably, a liquid inlet pipe is fixedly provided at the front end of the outer side of the mounting plate on one side, and the liquid inlet pipe is connected to one end of the circulation pipe. A liquid outlet pipe is fixedly provided at the rear end of the outer side of the mounting plate on the other side, and the liquid outlet pipe is connected to the other end of the circulation pipe.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model can intercept dust in the air through the first filter plate and the second filter plate. When the heat exchanger is in use, the air moves toward the surface of the first filter plate and the second filter plate together with the dust. When the air passes through the first filter plate and the second filter plate, the dust in the air will be intercepted by the filter screen, so that the clean air enters the interior of the first filter plate and the second filter plate and contacts the heat dissipation fins. At this time, the air with lower temperature absorbs the temperature on the heat dissipation fins. After using for a period of time, the first bolt and the second bolt are respectively rotated to make the first bolt and the second bolt move outward from the first threaded hole and the second threaded hole respectively through the external thread until the first bolt and the second bolt are detached from the mounting plate, and then the first filter plate and the second filter plate are removed from the mounting plate and the dust on the filter screen is cleaned. When the first filter plate and the second filter plate are dry, they are reinstalled on the mounting plate to prevent dust in the air from adhering to the heat dissipation fins.

[0015] 2. The utility model can buffer the vibrations generated by other machines during operation through the fixing seat and rubber pad. When installing the heat exchanger, the fixing seat is placed in the installation area. At this time, the rubber pad at the lower end of the fixing seat contacts the installation surface. Then the threaded rod is passed through the through hole and rotated into the groove inside the installation surface. As the threaded rod rotates downward, the fixing seat moves downward and squeezes the rubber pad until the threaded rod is rotated to a suitable position. If other machines vibrate, the vibration will squeeze the rubber pad. The vibration is absorbed by the extrusion deformation of the rubber pad, which prevents the vibration from being transmitted to the mounting plate through the fixing seat, thereby improving the heat exchange efficiency.

[0016] 3. The utility model is provided with a magnetic strip, which can preliminarily fix the first filter plate and the second filter plate. When installing the first filter plate and the second filter plate, the first filter plate and the second filter plate are first placed in the grooves between the mounting plates on both sides. At this time, the magnetic strips on the first filter plate and the second filter plate and the magnetic strips in the grooves of the mounting plates are attracted to each other by magnetic force, so that the first filter plate and the second filter plate are preliminarily fixed. At this time, when the positions of the first filter plate and the second filter plate need to be adjusted, the first filter plate and the second filter plate are pushed to slide in the grooves of the mounting plates until the first filter plate and the second filter plate are moved to appropriate positions. At this time, the first bolt and the second bolt are used to fix the first filter plate and the second filter plate respectively, avoiding the need for additional operators to fix the first filter plate and the second filter plate by hand. At the same time, the first filter plate and the second filter plate can be prevented from falling from the mounting plates when fine-tuning the positions of the first filter plate and the second filter plate.

[0029] See also Figure 2 and Figure 3 A circulation pipe 2 is provided in the middle position between the mounting plates 1 on both sides. The circulation pipe 2 is bent and distributed alternately.

[0031] Working principle: When installing the heat exchanger, place the fixing seat 10 in the installation area. At this time, the rubber pad 12 at the lower end of the fixing seat 10 contacts the installation surface. Then, pass the threaded rod through the through hole 11 and rotate it into the groove inside the installation surface. As the threaded rod rotates downward, the fixing seat 10 moves downward and squeezes the rubber pad 12 until the threaded rod rotates to a suitable position. If other machines vibrate, the vibration will squeeze the rubber pad 12. The vibration is absorbed by the extrusion deformation of the rubber pad 12. When installing the first filter plate 4 and the second filter plate 5, first place the first filter plate 4. The first filter plate 4 and the second filter plate 5 are placed in the groove between the mounting plates 1 on both sides. At this time, the magnetic strips 14 on the first filter plate 4 and the second filter plate 5 and the magnetic strips 14 in the groove of the mounting plate 1 are attracted to each other by magnetic force, so that the first filter plate 4 and the second filter plate 5 are initially fixed. At this time, when the positions of the first filter plate 4 and the second filter plate 5 need to be adjusted, the first filter plate 4 and the second filter plate 5 are pushed to slide in the groove of the mounting plate 1 until the first filter plate 4 and the second filter plate 5 are moved to the appropriate position. At this time, the first bolt 7 and the second bolt 8 are used to fix the first filter plate 4 and the second filter plate 5 respectively.
