Description

双缸V型柴油机强制风冷装置Two-cylinder V-type diesel engine forced air cooling device

本实用新型涉及燃烧式发动机，是一种活塞式燃烧发动机的部件，具体地说，是活塞式燃烧发动机的风冷式冷却装置。The utility model relates to a combustion engine, which is a component of a piston combustion engine, specifically an air-cooled cooling device for a piston combustion engine.

现有的风冷柴油机，如170F、165F等柴油机，是采用离心飞轮风扇来冷却气缸套和气缸盖的。离心飞轮风扇鼓出的风是顺导风罩涡壳的切线方向传出的，具有极强的方向性，不可以冷却其它方向(如V型夹角气缸)，即飞轮风扇无法同时对二个方向进行冷却。这也就实际影响到V型柴油机的性能和实用性。Existing air-cooled diesel engines, such as diesel engines such as 170F and 165F, adopt the centrifugal flywheel fan to cool the cylinder liner and the cylinder head. The wind blown by the centrifugal flywheel fan is transmitted along the tangential direction of the volute of the air guide cover. It has strong directionality and cannot cool other directions (such as V-shaped angled cylinders). direction for cooling. This also actually affects the performance and practicality of the V-type diesel engine.

本实用新型的目的是提供一种用单个飞轮风扇就能同时可二个方向的气缸进行强制风冷，结构简单，实用效果好的双缸V型柴油机强制风冷装置。The purpose of the utility model is to provide a dual-cylinder V-type diesel engine forced air-cooling device with simple structure and good practical effect, which can be used for forced air-cooling of cylinders in two directions at the same time with a single flywheel fan.

本实用新型的技术解决方案是：一种双缸V型柴油机强制风冷装置，其采用了现有技术中所没有采用的结构设计：包括风扇外壳，风扇外壳内装有飞轮风扇，在风扇外壳内侧壁装有导流板。The technical solution of the utility model is: a double-cylinder V-type diesel engine forced air cooling device, which adopts a structural design that is not used in the prior art: it includes a fan casing, and a flywheel fan is installed inside the fan casing. The walls are equipped with deflectors.

本实用新型中所述的风扇外壳包括风扇罩壳和风扇底板，导流板装于风扇罩壳的内侧或风扇底板的内侧。导流板有1-5个。导流板与风扇罩壳或风扇底板一体制成(或采用粘接、焊接等结构)。导流板的主体位于风扇罩壳与风扇底板之间。导流板的形状为圆弧形或渐开线形或其它合适的形状。当然，也可以采用其它合适的结构形式。The fan casing described in the utility model includes a fan casing and a fan bottom plate, and the deflector is mounted on the inside of the fan casing or the inside of the fan bottom plate. There are 1-5 deflectors. The deflector is made integrally with the fan casing or the fan bottom plate (or adopts bonding, welding and other structures). The main body of the deflector is located between the fan casing and the fan bottom plate. The shape of the deflector is circular arc or involute or other suitable shapes. Of course, other suitable structural forms can also be adopted.

本实用新型的优点是：结构简单，附件少，能有效合理地分配风量，能用单个风冷风扇同时冷却二个气缸，使V型柴油机的风冷系统更为有效和合理。The utility model has the advantages of simple structure, few accessories, can effectively and reasonably distribute the air volume, and can simultaneously cool two cylinders with a single air-cooling fan, making the air-cooling system of the V-type diesel engine more effective and reasonable.

以下结合附图和实施例对本实用新型作进一步的说明；Below in conjunction with accompanying drawing and embodiment the utility model is further described;

附图为本实用新型的一种双缸V型柴油机强制风冷装置的结构示意图。The accompanying drawing is a structural schematic diagram of a forced air cooling device for a twin-cylinder V-type diesel engine of the present invention.

附图描述了本实用新型的一个实施例。在该例中，包括风扇外壳1、2，风扇外壳1、2内装有飞轮风扇3，在风扇外壳1、2内侧壁装有导流板4。风扇外壳1、2包括风扇罩壳1和风扇底板2，导流板4装于风扇罩壳1的内侧或风扇底板2的内侧。导流板4有一个或多个(如2-5个)。这些导流板4与风扇罩壳1和风扇底板2一起形成了风量的分流通道，使原本沿切线方向的A气缸的风量，有部分沿导流板4形成的分流流向B气缸，导流板4使得靠近飞轮风扇3之间产生聚压，提高了进入B气缸的风量压力，综合起来，就使B气缸与A气缸同时得到了良好的冷却。导流板4与风扇罩壳1或风扇底板2一体制成(或采用粘接、焊接等其它连接结构)。导流板4的主体位于风扇罩壳1与风扇底板2之间。导流板4的形状为圆弧形或渐开线形或其它合适的形状。The accompanying drawings describe an embodiment of the utility model. In this example, fan housings 1 and 2 are included, and a flywheel fan 3 is housed in the fan housings 1 and 2 , and a deflector 4 is installed on the inner wall of the fan housings 1 and 2 . The fan casings 1 and 2 include the fan casing 1 and the fan bottom plate 2 , and the deflector 4 is mounted on the inner side of the fan casing 1 or the fan bottom plate 2 . There are one or more deflectors 4 (such as 2-5). These deflectors 4 together with the fan casing 1 and the fan bottom plate 2 form a flow distribution channel for the air volume, so that the air volume of the A cylinder originally along the tangential direction flows to the B cylinder along the diversion formed by the deflector 4, and the deflector 4 Make pressure build-up between the fan 3 close to the flywheel, improve the air volume pressure entering the B cylinder, combined, just make the B cylinder and A cylinder obtain good cooling simultaneously. The deflector 4 is integrally made with the fan casing 1 or the fan bottom plate 2 (or adopts other connection structures such as bonding and welding). The main body of the deflector 4 is located between the fan casing 1 and the fan bottom plate 2 . The shape of the deflector 4 is arc-shaped or involute-shaped or other suitable shapes.
