技术领域technical field
本发明涉及一种液压设备，具体是指防破损的液压油管路换热装置。The invention relates to hydraulic equipment, in particular to a breakage-proof hydraulic oil pipeline heat exchange device.
背景技术Background technique
自动变速车辆中设有油冷却器，用于对变矩器或动力传动系统中的发动机机油进行冷却，高温机油进入冷却器后与冷却器中的发动机冷却水进行热交换，进而对机油进行冷却。传统的散热器工作时，会由于闭式液压系统中流出的机油的瞬间压力过大从而对散热器造成损坏，影响散热器的正常工作。There is an oil cooler in an automatic transmission vehicle, which is used to cool the engine oil in the torque converter or power transmission system. After entering the cooler, the high-temperature oil exchanges heat with the engine cooling water in the cooler, and then cools the oil. . When the traditional radiator is working, the instantaneous pressure of the engine oil flowing out of the closed hydraulic system will be too high, which will damage the radiator and affect the normal operation of the radiator.
发明内容Contents of the invention
本发明的目的在于提供防破损的液压油管路换热装置，避免闭式液压系统中流出的机油的瞬间压力过大从而对散热器造成损坏。The purpose of the present invention is to provide an anti-damage hydraulic oil pipeline heat exchange device to avoid damage to the radiator caused by the instantaneous pressure of the engine oil flowing out of the closed hydraulic system.
本发明的目的通过下述技术方案实现：The object of the present invention is achieved through the following technical solutions:
防破损的液压油管路换热装置，包括壳体以及弯曲折叠放置在壳体内的换热管，在壳体的同一侧设置有分别与换热管两端连通的进液口、出液口，在所述壳体的另一侧设有与其内部连通的冷液进口、冷液出口，在所述换热管靠近出液口方向的一端上侧内壁上设有半圆形的突出部，且在所述突出部的两端设有截面为圆弧状的过渡段，在换热管对应的下侧内壁上设置有沿其径向向外突出的调节槽，在调节槽内安装有半圆形的活动块，且活动块的两端通过风琴式密封罩与换热管内壁连接，在靠近所述出液口一端的调节槽的端部上安装有弹簧，且弹簧与活动块侧壁连接。The anti-damage hydraulic oil pipeline heat exchange device includes a shell and a heat exchange tube bent and folded in the shell. On the same side of the shell, a liquid inlet and a liquid outlet are respectively connected to both ends of the heat exchange tube. The other side of the housing is provided with a cold liquid inlet and a cold liquid outlet communicating with the interior, and a semicircular protruding part is provided on the inner wall of the heat exchange tube at one end close to the direction of the liquid outlet, and Both ends of the protruding part are provided with a transition section with a circular arc shape, and an adjustment groove protruding outward along the radial direction is arranged on the inner wall corresponding to the lower side of the heat exchange tube, and a semicircle is installed in the adjustment groove. Shaped movable block, and the two ends of the movable block are connected to the inner wall of the heat exchange tube through an organ-type sealing cover, and a spring is installed on the end of the regulating tank near the end of the liquid outlet, and the spring is connected to the side wall of the movable block .
本发明使用时，冷却液通过冷液进口进入到壳体内部，当壳体内注满冷却液时液压油由进液口流入换热管内，通过换热管与壳体内冷却液的热交换工序，使得液压油的温度被快速降低，然后由出液口排出，以此完成液压油的冷却循环使用。在液压油冷却即将结束时，液压油在换热管内快速流动，由出液口流出时高速流动的液压油会对液压油输送管造成较大的冲击，进而导致整个冷却循环管路中出现局部受力集中而出现破裂，即出现漏油现象；本发明中，在液压油流出出液口之前，在换热管的上侧内壁上安装有半圆形的突出部，同时在换热管下侧内壁上设有调节槽，活动块滑动设置在调节槽内，而调节槽通过风琴式密封罩与换热管隔离开，而活动块的上端突出于风琴式密封罩的上表面，使得在液压油高速流动时，直接对活动块形成冲击，活动块则在调节槽内做直线运动，当活动块移动至与突出部正对时，此时弹簧被压缩，液压油的流道内径大小骤然变小，活动块与突出部相互配合，以实现液压油的流速减缓，液压油则以一个相对缓慢的流速流出出液口，即实现降低液压油对冷却循环管路的冲击，以防止冷却循环管路受损破裂；而当液压油的流量与流速相对较小时，弹簧回复形变使得活动块与突出部相错开，使得液压油的流道重新增大，保证液压油的正常流通。并且，在突出部的两端设置有一个截面为圆弧状的过渡段，使液压油在骤然减速后平缓地流入突出部内，同时对液压油起到一个导引作用，即引导液压油由换热管直接进入到突出部内，避免液压油在换热管形成涡流而阻碍其正常流通。When the present invention is used, the cooling liquid enters the inside of the housing through the cooling liquid inlet, and when the housing is filled with cooling liquid, the hydraulic oil flows into the heat exchange tube from the liquid inlet, and through the heat exchange process between the heat exchange tube and the cooling liquid in the housing, The temperature of the hydraulic oil is rapidly reduced, and then discharged from the liquid outlet, so as to complete the cooling cycle of the hydraulic oil. When the cooling of the hydraulic oil is about to end, the hydraulic oil flows rapidly in the heat exchange tube, and the high-speed flowing hydraulic oil will cause a large impact on the hydraulic oil delivery tube when it flows out from the liquid outlet, which will lead to partial failure in the entire cooling cycle pipeline. Cracks occur due to concentrated force, that is, oil leakage occurs; in the present invention, before the hydraulic oil flows out of the liquid outlet, a semicircular protrusion is installed on the upper inner wall of the heat exchange tube, and at the same time, under the heat exchange tube There is an adjustment groove on the side inner wall, and the movable block is slidingly set in the adjustment groove, and the adjustment groove is separated from the heat exchange tube by the organ-type sealing cover, and the upper end of the movable block protrudes from the upper surface of the organ-type sealing cover, so that the hydraulic pressure When the oil flows at high speed, it directly impacts the movable block, and the movable block moves linearly in the adjustment groove. When the movable block moves to face the protrusion, the spring is compressed at this time, and the inner diameter of the flow channel of the hydraulic oil suddenly changes. Small, the movable block and the protrusion cooperate with each other to slow down the flow rate of the hydraulic oil, and the hydraulic oil flows out of the liquid outlet at a relatively slow flow rate, that is, to reduce the impact of the hydraulic oil on the cooling circulation pipeline to prevent the cooling circulation pipeline from cooling. When the flow and velocity of the hydraulic oil are relatively small, the spring returns and deforms to make the movable block and the protruding part stagger, so that the flow channel of the hydraulic oil increases again to ensure the normal circulation of the hydraulic oil. Moreover, a transition section with a circular arc-shaped cross-section is provided at both ends of the protruding part, so that the hydraulic oil flows smoothly into the protruding part after a sudden deceleration, and at the same time plays a guiding role for the hydraulic oil, that is, guides the hydraulic oil from changing The heat pipe directly enters the protruding part, preventing the hydraulic oil from forming a vortex in the heat exchange pipe and hindering its normal circulation.
所述换热管为翅片管。作为优选，选用翅片管作为换热管，利用翅片管上的突出的多个翅片来增加换热管与壳体内冷却液的接触面积，实现液压油与冷却液之间热交换的最大效率，缩短液压油的冷却时间。The heat exchange tubes are finned tubes. As a preference, the finned tube is selected as the heat exchange tube, and the protruding multiple fins on the finned tube are used to increase the contact area between the heat exchange tube and the cooling liquid in the shell, so as to realize the maximum heat exchange between the hydraulic oil and the cooling liquid. Efficiency, shorten the cooling time of hydraulic oil.
所述突出部的厚度为所述换热管内径的三分之一。突出部的厚度比换热管的内径小，在保证液压油的正常流通而不至于形成堵塞的前提下，将突出部的厚度大小设置为换热管内径大小的三分之一，使得液压油的流速减缓而不会形成对冷却循环管路的冲击。The thickness of the protruding part is one-third of the inner diameter of the heat exchange tube. The thickness of the protrusion is smaller than the inner diameter of the heat exchange tube. On the premise of ensuring the normal circulation of the hydraulic oil without causing blockage, the thickness of the protrusion is set to one-third of the inner diameter of the heat exchange tube, so that the hydraulic oil The flow rate is slowed down without forming an impact on the cooling circuit.
本发明与现有技术相比，具有如下的优点和有益效果：Compared with the prior art, the present invention has the following advantages and beneficial effects:
1、本发明在突出部的两端设置有一个截面为圆弧状的过渡段，使液压油在骤然减速后平缓地流入突出部内，同时对液压油起到一个导引作用，即引导液压油由换热管直接进入到突出部内，避免液压油在换热管形成涡流而阻碍其正常流通；1. In the present invention, a transition section with a circular arc-shaped cross-section is provided at both ends of the protrusion, so that the hydraulic oil flows smoothly into the protrusion after a sudden deceleration, and at the same time plays a guiding role for the hydraulic oil, that is, guides the hydraulic oil The heat exchange tube directly enters the protruding part, preventing the hydraulic oil from forming a vortex in the heat exchange tube and hindering its normal circulation;
2、本发明选用翅片管作为换热管，利用翅片管上的突出的多个翅片来增加换热管与壳体内冷却液的接触面积，实现液压油与冷却液之间热交换的最大效率，缩短液压油的冷却时间；2.
