Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchangers, and particularly relates to a plate-fin type oil cooler which is convenient to disassemble. Background Art

[0002] Oil cooler is a kind of oil cooling equipment commonly used in hydraulic system and lubrication system. It can realize heat exchange between two fluid media with a certain temperature difference, so as to reduce the oil temperature and ensure the normal operation of the system. Oil cooler can be divided into air-cooled oil cooler and water-cooled oil cooler according to the different heat exchange media. Water-cooled oil cooler can be divided into tube oil cooler and plate oil cooler. Plate oil cooler can be divided into detachable plate oil cooler and brazed plate oil cooler. Oil cooler is widely used in plastic machinery, engineering machinery, mining machinery, automobile, steel, wind power, aerospace and other industries, but it still has the following disadvantages in actual use:

[0003] The utility model with publication number CN202221258U discloses a plate-fin oil cooler, wherein a heat exchange core is installed between the heads, and the joint is connected to the cooling oil channel of the heat exchange core. The heat exchange core is composed of a heat exchange fin layer and a cooling oil channel layer which are staggered and overlapped; the heat exchange fin layer is connected by parallel partitions and fins installed between the parallel partitions, and a cooling oil channel layer is formed between the partitions of two adjacent fin layers; the two ends of the cooling oil channel layer are respectively connected to the left head and the right head in a sealed manner, and the left head and the right head are respectively connected to the left joint pipe and the right joint pipe in a sealed manner; between the parallel partitions of the heat exchange fin layer and the fins, The two ends of the cooling oil channel are respectively connected to the left and right heads, and the left and right heads are respectively connected to the left and right joint pipes by vacuum brazing layers. Compared with the detachable plate oil cooler, the brazed plate oil cooler can withstand higher fluid pressure, ensuring the stability and service life of the oil cooler under high fluid pressure for a long time. However, since the oil cooler is easy to be blocked, it needs to be cleaned by backwashing and other methods. The heat exchange plate is easy to be damaged for a long time, but the brazed plate oil cooler is difficult to disassemble and maintain, which increases maintenance expenses;

[0004] When the plate-fin oil cooler exchanges heat for the fluid, impurities in the fluid may be blocked between the fins, causing the fluid flow rate to decrease, the fluid pressure to increase, and the heat exchange efficiency of the plate-fin oil cooler to decrease. Utility Model Content

[0005] The utility model aims to provide a plate-fin oil cooler that is easy to disassemble. By supporting the outer shell, the connecting frame and the heat exchange plate, the utility model solves the problem that the detachable plate oil cooler is easy to disassemble and maintain, but can withstand a relatively small fluid pressure, and impurities in the fluid may be blocked in the fins when passing through the oil cooler, resulting in a decrease in the fluid flow rate, an increase in the fluid pressure, and a reduction in the heat exchange efficiency of the plate-fin oil cooler.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a plate-fin oil cooler that is easy to disassemble, comprising a supporting shell, a connecting frame and a heat exchange plate, wherein a plurality of supporting plates are welded and fixed in the supporting shell, a silicone heat conducting plate is inserted through one side of each supporting plate, a connecting frame is attached to one side of the supporting shell, two oil pipes and water pipes are respectively inserted and welded through the two sides of the connecting frame, a plurality of heat exchange plates are inserted in the supporting shell, a plurality of heat exchange fins are welded and fixed in each heat exchange plate, a crushing knife is welded and fixed at one end of each heat exchange fin, and one supporting plate is attached between two adjacent heat exchange plates;

[0008] The silicone heat-conducting plate can be supported by the support plate, and multiple heat-exchanging plates can be separated, which is convenient for disassembly and replacement of the heat-exchanging plates. The silicone heat-conducting plate can conduct heat between two adjacent heat-exchanging plates, so that the heat of the hot oil is quickly transferred to the cooling water. At the same time, since the silicone heat-conducting plate has a certain elasticity, it can buffer both sides of the heat-exchanging plate when the hydraulic pressure is large, reduce the probability of damage to the heat-exchanging plate, and improve the stability of the oil cooler. When it is necessary to disassemble and replace a single heat-exchanging plate, it is only necessary to remove the connecting frame to release the limit of the supporting shell and the connecting frame on a large number of heat-exchanging plates, so as to quickly take out the heat-exchanging plates that need to be replaced. The operation is simple and convenient. When the fluid passes through the heat-exchanging plate, the heat-exchanging fins can greatly increase the heat-exchanging area of ​​the heat-exchanging plate and improve the heat-exchanging efficiency. When impurities pass between the two heat-exchanging fins, the particles first collide with the crushing knife to crush the particles, so that the crushed small particles can pass between the two heat-exchanging fins, avoiding a large number of granular impurities from being blocked in the heat-exchanging plate, thereby ensuring the heat-exchanging efficiency.

[0009] Furthermore, a plurality of threaded holes are provided on one side of the support shell, the connecting frame is located on one side of the threaded holes of the support shell, and a support net is clamped and fixed on both sides of each support plate;

[0010] The support net can support the silicone heat conduction plate to avoid deformation of large-area silicone heat conduction plates. The silicone heat conduction plate can conduct heat between two adjacent heat exchange plates, so that the heat of the hot oil is quickly transferred to the cooling water. At the same time, since the silicone heat conduction plate has a certain elasticity, it can buffer both sides of the heat exchange plate when the hydraulic pressure is large, reducing the probability of damage to the heat exchange plate and improving the stability of the oil cooler.

[0011] Furthermore, a bolt is inserted through one side of the connecting frame, and the oil pipe and the water pipe are inserted through one side of the supporting shell, the plurality of supporting plates and the supporting net, and one end of the bolt is screwed and fixed in the threaded hole;

[0012] By screwing and fixing the bolts in the threaded holes, the connecting frame and the supporting shell can be quickly connected, and multiple heat exchange plates can be further positioned to ensure the stability of the oil cooler during use. When the heat exchange plate needs to be replaced, only the bolts need to be screwed out and the connecting frame is pulled out to quickly take out the heat exchange plate that needs to be replaced. The operation is simple and convenient.

[0013] Furthermore, a mounting plate is welded and fixed to one end of the outer circumference of the two oil pipes and the water pipes, and a plurality of through holes are penetrated and opened at the other end of the outer circumference of the two oil pipes and the water pipes, and the plurality of mounting plates are located on the other side of the connecting frame relative to the supporting shell;

[0014] The oil cooler can be connected to other devices through the mounting plate, so that the oil and cold water can exchange heat through the oil cooler.

[0015] Furthermore, a lifting handle is provided on the top of one side of each heat exchange plate, and plug-in ports are provided at both ends of one side of each heat exchange plate, and an oil pipe or a water pipe is inserted through the plug-in port of one heat exchange plate;

[0016] The heat exchange plate that needs to be replaced can be quickly pulled out of the supporting shell by the lifting handle, and the heat exchange plates connected to the oil pipe and the water pipe are alternately arranged in the supporting shell. When the oil passes through one heat exchange plate, the heat of the oil is transferred to the two adjacent heat exchange plates connected to the water pipe, and the oil is cooled by cold water.

[0017] Furthermore, each of the heat exchange plates is provided with a heat exchange groove, the heat exchange fins are located in the heat exchange groove, both ends of the other side of each of the heat exchange plates are clamped and fixed with sealing rings, the oil pipe or water pipe is inserted through one side of a heat exchange plate, the sealing ring is pressed and fitted on the outer peripheral surface of the oil pipe or water pipe, and the heat exchange groove and the through hole of the oil pipe or water pipe are connected through and through;

[0018] When the oil passes through the heat exchange plate, the heat exchange fins can greatly increase the heat exchange area of ​​the heat exchange plate and improve the heat exchange efficiency. When impurities pass between the two heat exchange fins, the particles first collide with the crushing knife to crush the particles, so that the crushed small particles can pass between the two heat exchange fins, avoiding a large number of granular impurities from clogging the heat exchange plate and ensuring the heat exchange efficiency.

[0019] The utility model has the following beneficial effects:

[0020] The utility model solves the problem that the brazed plate oil cooler can withstand higher fluid pressure than the detachable plate oil cooler by arranging a supporting shell, a connecting frame and a heat exchange plate, thereby ensuring the stability and service life of the oil cooler when it is used under high fluid pressure for a long time. However, since the oil cooler is easy to be blocked, it needs to be cleaned by backwashing and the like, and the heat exchange plate is easy to be damaged after a long time. However, the disassembly and maintenance of the brazed plate oil cooler is relatively difficult, which increases the maintenance cost. When the oil cooler exchanges heat with the oil, the pressure generated by the fluid can be buffered by the silicone heat conductive plate with a certain elasticity, thereby reducing the probability of damage to the heat exchange plate and improving the stability of the oil cooler. When a single heat exchange plate needs to be replaced, the bolts can be screwed off and the connecting frame can be pulled out, so that the limit of all heat exchange plates can be released, which is convenient for the staff to quickly take the heat exchange plate that needs to be replaced, while ensuring the convenience of disassembly and assembly of the detachable plate oil cooler, the damage caused to the heat exchange plate by the fluid pressure is reduced.

[0021] The utility model solves the problem that when a plate-fin oil cooler exchanges heat for a fluid, impurities in the fluid may be blocked between the fins, causing the fluid flow rate to drop, the fluid pressure to rise, and the heat exchange efficiency of the plate-fin oil cooler to be reduced by arranging a heat exchange plate. When the oil enters the heat exchange plate, the impurity particles in the oil first collide with the crushing knife to crush the particles, so that the crushed small particles can pass between the two heat exchange fins, thereby avoiding a large number of granular impurities from being blocked in the heat exchange plate and ensuring the heat exchange efficiency.
