Description

Hybrid cooling system arrangement structure

Technical Field

The utility model belongs to the technical field of the car, concretely relates to hybrid cooling system arrangement structure.

Background

The plug-in hybrid technology can realize long-distance driving like a traditional vehicle, and meanwhile, energy is saved in a hybrid mode, and emission is reduced. The system can realize short-distance zero emission in a pure electric mode, the gasoline engine stops working at the moment, clean and environment-friendly effects are completely realized, and meanwhile, under the whole operation working condition, the system can intelligently switch between two power sources according to the requirements of a driver, the SOC state of a battery, the load of an engine, environmental factors and the like, and the energy recovery is realized to the maximum extent. The integral integrated oil consumption can reach 2L/100 km.

In the vehicle type, a large-capacity power battery needs to be configured due to long pure electric mileage, and meanwhile, one to 2 or 3 high-power motors, a corresponding control system and the like are generally needed due to the requirement of hybrid power multi-mode, so that the weight of the whole vehicle is greatly increased. Under extreme conditions, the engine load of the vehicle is increased sharply relative to the basic fuel vehicle. Meanwhile, due to the increase of new power sources, more components needing to be cooled by a cooling system are brought, generally, cold air at the front end is needed for cooling, more heat exchangers are accumulated at the front end, and the air intake of a main radiator of the engine is greatly reduced. Meanwhile, more radiators can bring more heat exchange and the inlet air temperature of the main radiator of the engine, so that the radiating conditions of the main radiator are poor and the radiating performance cannot be guaranteed. In addition, these additional heat loads and wind resistances also affect air conditioning performance. With the improvement of the performance requirement of the vehicle, the supercharged engine is already the current vehicle standard, and the front end also needs an air intercooler, namely, the front end of a general supercharged engine traditional vehicle is generally provided with an intercooler, a condenser, a main radiator and at least 3 radiators. After the hybrid vehicle is converted into a hybrid vehicle, a low-temperature radiator of a motor control system (a circuit generally comprises a charger, an inverter, a DCDC and the like) and a transmission oil-temperature radiator (a motor is generally integrated therein) are required to be additionally arranged, and even a low-temperature radiator of a battery cooling system may be arranged. A total of at least 4-6 heat sinks.

In general, in order to use a front-end large fan, it is necessary to arrange the plurality of radiators simultaneously at the front end of the vehicle. Meanwhile, in order to ensure the air intake, the opening area of the air inlet grille must be increased. The opening is enlarged, on one hand, after the opening reaches a certain degree, the air quantity is hardly increased along with the enlargement of the opening; on the other hand, the larger opening increases the wind resistance, increases the fuel consumption, and in turn increases the engine load, which in turn deteriorates the engine heat radiation performance. When the opening is increased, but the performance of the main radiator is still not satisfied, all the previous solutions may also adopt: 1) the performance of the radiator is improved, and 2) the working condition is protected. The first kind of condition all can lead to the increase of radiator size, leads to unable fixed mounting under former automobile body structure, and the second kind has obviously reduced user's use and has experienced.

Plug-in hybrid power generation is generally developed based on a crude fuel vehicle platform, the arrangement of the front end is very difficult due to a plurality of radiators, the air intake of the main radiator of the engine is greatly reduced, and the cooling system of the engine fails under extreme working conditions. If all are arranged at the front end, the method can be adopted only by newly developing a main radiator, increasing the power of a fan, increasing the opening of a grid, having excellent sealing performance and newly adding a plurality of new heat exchangers. Even the water tank cross beam needs to be opened again. The improvement amount and the cost are large, and the feasibility of the scheme is not high.

Detailed Description

The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings, for the purpose of helping those skilled in the art to understand more completely, accurately and deeply the conception and technical solution of the present invention, and to facilitate its implementation. It should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. In the following embodiments, the terms "first", "second" and "third" do not denote absolute differences in structure and/or function, nor do they denote a sequential order of execution, but rather are used for descriptive convenience only.

As shown in fig. 1, a hybrid cooling system arrangement structure includes an intercooling radiator 1, a condenser 2 and a main radiator 3 which are arranged at the front end of a vehicle body, the intercooling radiator 1, the condenser 2 and the main radiator 3 form a front end cooling module, the arrangement structure further includes an auxiliary radiator which is laterally arranged at the side surface of the front end of the vehicle body, and an air inlet is formed by opening a side grille. And opening the air inlet of the side grille to form an independent air path cooling circuit. When the air cooling system is arranged, two or three mutually independent air cooling loops are preferably formed, and compared with a single air loop cooling system, the air cooling system has the advantages of large air intake, low heat load, few newly developed parts and good cooling performance. Due to the structural arrangement, the risk that the engine cooling system fails under the original investigation working condition due to the fact that all the newly added cooling systems are arranged at the front end is avoided. The auxiliary radiator is preferably an oil cooler 4 provided behind the fog lamp 5. The oil cooler 4 can be arranged behind the left fog lamp or the right fog lamp, or can be arranged in two. Namely, the oil cooler 4 is arranged behind the left fog lamp and/or the right fog lamp. Correspondingly, the side grille is a fog lamp grille.

In order to facilitate better arrangement and installation of the oil cooler, the oil cooler 4 is connected with a front protective beam 7 through a bracket 6. As shown in figure 2, the support comprises a connecting plate and a mounting plate, the mounting point of the oil cooler is connected with one end of the connecting plate through a fastener, and the other end of the connecting plate is fixedly connected with the front protective beam through the mounting plate. The oil cooler is fixed on the front protective beam through the support, and the stability after assembly is guaranteed.

When the radiator is specifically arranged, the required framework is preliminarily designed according to the power system and the cooling requirement of the whole vehicle, and then whether space is left or not is judged according to the basic vehicle type. If the radiator is arranged at the front end completely and cannot meet the performance requirement or the performance can be met by trying to arrange the radiator at the front end, but the side arrangement is superior to the side arrangement cost, the radiator can be arranged at the side on the premise of continuing to use the original cooling system. And adding a radiator, and analyzing or evaluating whether a small fan needs to be configured or not according to the heat load characteristics of a heating system of the radiator.

Examples are as follows: for basic fuel models carrying turbocharged engines, the front end has been arranged with: an intercooling radiator 1 (low temperature radiator), a condenser 2 and a main radiator 3. When the vehicle type is used for developing PHEV vehicle types, a radiator needs to be added for a battery, a radiator needs to be added for an electric control system, and meanwhile, the heat of a hybrid special gearbox (integrating two driving motors) needs to be radiated. The battery system and the electric control system are both water-cooled, and the water temperature range is lower than 60 ℃, so that the space and the cost are saved, the battery system and the electric control system are combined with an intercooling radiator, namely the same radiator is used for radiating heat of three systems. The special hybrid transmission adopts oil cooling and has high temperature, so that a radiator is required to be used independently. In this example, the newly added oil cooler 4 has a large thermal load, and when all the oil coolers are placed at the front end, the temperature of the main radiator is excessively high, and even if the temperature is increased to the maximum opening ratio, the temperature cannot be satisfied. If the radiator is forced to be arranged in the front, the performance of the main radiator needs to be improved, the height and the thickness of the radiator need to be increased, the radiator cross beam needs to be newly developed, and the front safety cannot be guaranteed unless the front protection cross beam is also modified. The change volume and cost can not accept this scheme, consequently adopt and place the oil cooler side in the fog lamp rear, open the fog lamp grid according to the amount of wind demand simultaneously. In this case, the natural air volume of the running vehicle can satisfy the cooling requirement after analysis and calculation, and the loop can be configured without a cooling fan if no other special requirement exists. Of course, it is also possible to configure a small fan according to actual needs. After the side scheme is adopted, the front end part can completely follow the cooling system of the original basic vehicle type or be slightly modified. Through analysis, the opening ratio is increased compared with the original basic vehicle, but the opening ratio is within the normal range. The new scheme is verified and passed through the same condition test working condition, and the performance of the cooling system of the plug-in hybrid power is realized at the lowest cost.

The invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-described manner. Various insubstantial improvements are made by adopting the method conception and the technical proposal of the utility model; or without improvement, the above conception and technical solution of the present invention can be directly applied to other occasions, all within the protection scope of the present invention.
