Telling the world? Let’s talk about the earliest MPV The development of MPV has always followed the gradual improvement of people's needs. To trace back the development of MPV, it originally came from "Mini Van". In essence, "Van" is a (van), but after adding Mini, it shows that it is very different from those full-size vans that carry or carry more than seven people, that is, its biggest change is in use. On the transition, home started as a new direction of use. Although MPV is an independent model, it is still related to our traditional station wagon, the van VAN. To be precise, it is also a combination of them. The development direction of MPV in Europe, the United States and even Japan is different. However, we will take a look at the development of MPV together. The Stout Scarab launched in the United States in 1936 can be regarded as the ancestor of MiniVan. In the early stages of development, as chair of the American Society of Automotive Engineers, Stout found that cars at the time used a design that separated the car body from the frame (non-carrier chassis), and also adopted the conventional layout of the front engine rear wheel drive. Although this design has many advantages, because the front engine will compress the space, and the engine needs to use the drive shaft to the rear wheel, but also indirectly raised the platform, and narrow the space. Stout hopes to make a car that is similar in size to the car at the time, but has a larger space. So Stout Scarab turned out. Picture: Stout Scarab was designed before the war, and the streamlined body was a forward-looking design for automotive technology at the time. This van wagon is an unprecedented concept, in fact, is the "car plus truck", "comfort and load" design concept, and then the international market to carry forward such models and collectively referred to as "MPV." It is also now known as a utility vehicle. The G10 of SAIC Chase made a good summary of this advantage of MPV: "Appropriate to IKEA". Talk about improvement? MPV's changes The modern MPV received wide acclaim after the launch of Dodge Caravan, and many car manufacturers quickly responded by starting to develop MiniVan models. Photo: Dodge Caravan uses a sliding door design. Although this element was moved from Van, it has now become the standard for many medium and large MPVs. Dodge Caravan uses the S platform improved from the sedan's Chysler S platform. The chassis design of the car allows Dodge Caravan to approximate the driving characteristics of the car. Divided into two types of long/short wheelbase, it adopts a load-bearing chassis, front engine front wheel drive, and hatchback van design. There are 7 (2+3+2) and 5 (2+3) designs in the car, which are turned upside down at the tailgate. The sliding middle door is also a new design. This design element is also widely used. On the modern MPV and Van. Compared with the previous year, the sedan has more space and uses, and the price is also very low. It is highly sought after by everyone. Say this life? The new opportunity of the two-boy era Figure: SAIC Chase G10, 7-seater (2+2+3) design, with space as one of the selling points to meet the needs of second-child families. With the release of the two-child policy and the prevalence of family collective travel, MPV is essentially a good type of home car as a supplement to the wagon. The MPVs at various price points on the market are also very rich, ranging from 70,000 to several tens. If you are a family with more family members and love to travel, MPV is also a good choice. It brings you different surprises and car experiences in terms of function and space. For example, if the driver is upgraded, the automatic transmission and the manual transmission are equipped with two versions. The operation is also more stable, the shift is more rapid, and the noise reduction and upgrade are also made to make the driving noise lower, creating a good travel experience for the baby. Leading science and technology are also widely used in automotive design, such as car-link human-computer interaction system, touch-free automatic sensing door, 360-degree panoramic parking system, etc., not only improve driving comfort, but also take into account the intelligent experience and actual needs . Integrating technology, driving, and demand is a major feature of modern MPV.
Teflon is Polytetrafluoroetylene, referred to as Teflon, PTFE, F4, etc.It is also known as Teflon, Teflon, Teflon, Teflon and so on because of its pronunciation.Polytetrafluoroethylene (ptfe) is a kind of plastic, which is used to manufacture heaters. It has been successfully used in chemical equipment heating. It has the characteristics of multi-layer and three-dimensional heating.
The working pressure, working temperature, heat transfer coefficient and installation method of the teflon heater vary greatly according to different types, different shell materials and different thermal media.The chemical properties of teflon are very stable and the corrosion resistance is especially good.The surface of the teflon tube is smooth and moderately flexible, so it is not easy to scale due to the slight vibration when using it.The teflon heater is small in size and compact in structure. The heat transfer area per unit volume of the equipment is more than 4 times of that of the shell heater.Flexible teflon tubes work safely under shock and vibration of fluids, and the tubes can be made into special shapes as needed.Teflon has low thermal conductivity, poor mechanical properties than metal, and is not resistant to high temperature.The use of small diameter, thin wall, although the thermal conductivity and mechanical properties of compensation, but can only be used in the case of low pressure and low temperature.The production of teflon steam heater and teflon hot water heater has become more and more mature, and widely used in chemical industry, medicine, pickling and other corrosive industries.
