Description

Top-mounted vehicle engine intercooling system

technical field

The utility model relates to a vehicle engine system, in particular to a top-mounted vehicle engine intercooling system installed at the top of a vehicle cab, and belongs to the technical field of vehicle manufacturing.

Background technique

At present, vehicles with diesel engines, in order to improve economy and meet environmental protection emission requirements, basically adopt the technology of "air-to-air" cooling in the middle after the air intake system is pressurized, intercooler and radiator, Similar to the "series" connection, the common way is that the engine drives the fan through mechanical transmission (intermediately or in series to increase electric, hydraulic and other fan clutches), so that the external airflow passes through the intercooler and radiator in turn for heat dissipation. The internal intake temperature of the intercooler is about 150°C, and the external airflow is required to reduce it to the ambient temperature +10°C. Due to the air resistance characteristics of the intercooler's own structure, after the external airflow passes through the core of the intercooler for the first time, the flow rate and flow rate decrease a lot, but the temperature of the air supplied to the radiator for cooling rises a lot. In addition, the wind resistance characteristics of the radiator's own structure, Make the air velocity and the flow rate that flow through radiator again often can't satisfy actual demand. In addition, due to the feedback effect of the wind resistance of the radiator, the air intake volume and flow rate of the intercooler are also lower than the values in the unit test, so that the heat exchange effect of the intercooler is not good. The intercooler under the "series" system The heat exchange effect of radiator and radiator is very poor. Therefore, there is no way to effectively solve the matching between binary heat transfers so far. Since the engine is working in the whole process, the working requirements of the radiator and the intercooler are different. In the "series" system, in order to meet the working requirements, when any system needs to work, the fan must be made to work, resulting in unnecessary Energy consumption. Not in line with the social principles of energy conservation.

Contents of the invention

The purpose of the utility model is to overcome the above problems existing in the prior art, and to provide a top-mounted vehicle engine intercooling system.

Top-mounted vehicle engine intercooling system, involving the vehicle cab, including intercooler, fan and windshield, the fan is placed at the air inlet or outlet of the intercooler, wherein: the intercooler is set on the top of the vehicle cab .

The purpose of this utility model is achieved through the following technical solutions:

The top of the vehicle cab is provided with a guide cover, and the guide cover is provided with guide flow holes, the intercooling system is arranged in the guide cover, and the fan assembly is arranged corresponding to the guide flow holes. Furthermore, the position of the original radiator may not be changed.

The purpose of this utility model can also be further realized through the following technical measures:

In the intercooling system for the above-mentioned roof-mounted vehicle engine, the top of the vehicle cab is provided with a cavity, the cavity is provided with diversion holes, the intercooler system is arranged in the cavity, and the fan assembly is arranged corresponding to the diversion holes.

Further, in the intercooling system for the above-mentioned roof-mounted vehicle engine, the intercooler, the windshield, and the fan are combined to form an intercooling system, and the air ducts formed by the fans are isolated from each other.

The utility model has the advantages that: it can be clearly seen from the above text description combined with the accompanying drawings that after adopting the intercooler system for the overhead vehicle engine, the intercooler and the radiator can be connected in the traditional "serial" mode. separate. Moreover, the intercooler system is arranged at the top of the vehicle cab, which can not only effectively use the wind force during vehicle driving to help the intercooler dissipate heat, but also effectively utilize the overall space of the vehicle cab. At the same time, the fan and the windshield are composed of a separate fan assembly, and are equipped with mutually isolated air ducts, which is conducive to meeting the air flow requirements of the independent operation of the intercooler. The most important thing is: the intercooler and the radiator can dissipate heat independently and on demand, saving fuel. Therefore, the utility model patent has a good application prospect in the field of vehicle manufacture and is worthy of promotion.

The objects, advantages and features of the present invention will be illustrated and explained by the following non-limiting description of preferred embodiments, which are given by way of example only with reference to the accompanying drawings.
