Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of radiators, and in particular relates to a mounting structure of a fan on a radiator. Background Art
[0002] As national environmental protection policies continue to improve, non-road vehicles are entering the National IV emission standard. To meet these new regulations, exhaust treatment equipment is installed at the rear end of the engine exhaust. This high-temperature aftertreatment system occupies a large portion of the bulldozer cabin. The cooling fan is driven by a hydraulic motor instead of a direct engine drive, resulting in high speed, high air volume, and excellent heat dissipation.
[0003] Currently, there are two main structures for fixed hydraulic motors in the industry. Both structures require additional mounting brackets. One bracket is fixed to the radiator, and the other is fixed to the front hood. Compared with the compact space in the bulldozer cabin, both installation methods are very difficult to remove the radiator during later maintenance, and the cost is also relatively high. Utility Model Content
[0004] In order to solve the technical problem in the background art that the installation of the cooling fan requires an additional mounting bracket, the purpose of the present utility model is to provide a mounting structure for the fan on a radiator, which can solve the above problem.
[0005] The technical solution for achieving the purpose of the utility model is: a mounting structure for a fan on a radiator, comprising a radiator, a fan, a fan guard net and a driver, wherein the radiator is mounted on one side of the front hood of the bulldozer, and the fan guard net is mounted on the other side of the front hood of the bulldozer; the fan is mounted between the fan guard net and the radiator, and the driver is mounted on the side of the fan guard net away from the fan, and the driver is connected to the fan for driving the rotation of the fan.
[0006] This solution involves installing a radiator on one side of the bulldozer's front hood and a fan on the other side. The bulldozer's front hood has a through-hole that connects the radiator and fan guard, allowing heat dissipation when the fan rotates. The fan's specific installation structure involves installing a fan guard on the other side of the bulldozer's front hood to protect the fan, and installing a driver similar to a hydraulic motor on the fan guard. The driver drives the fan's rotation, eliminating the need for a separate bracket installation and saving space. During subsequent maintenance, only the fan guard needs to be removed to perform comprehensive maintenance on the fan guard, fan, driver, and radiator. This facilitates assembly and disassembly, is highly efficient, and is cost-effective.
[0007] Further, the heat dissipator is provided with a wind deflector, and the fan guard net is installed on the wind deflector. The fan guard net does not need to be additionally punched on the bulldozer front hood, and when the heat dissipator needs to be maintained, the fan guard net is only needed to be removed, so that the heat dissipator can be easily removed from the bulldozer front hood, which is convenient and efficient.
[0008] Further, the wind deflector is provided with a first mounting hole, the fan guard net is provided with a corresponding second mounting hole, and the fan guard net is installed and fixed through cooperation of the first mounting hole, the second mounting hole and a first bolt. The bolt and the mounting hole are used for installation, which is convenient and efficient. In addition, a gasket can be used for installation.
[0009] Further, the driver is a hydraulic motor, which is small in size, high in rotating speed and good in heat dissipation effect. Further, the hydraulic motor is installed on the fan guard net through a transition support. After the transition support is installed on the fan guard net, the hydraulic motor has a structure that can be fixed and supported, so that the fan can be close to the heat dissipator instead of being close to the fan guard net, thereby ensuring the sinking amount of the fan to the heat dissipator and improving the heat dissipation effect.
[0010] Further, the fan guard net is provided with a third mounting hole, the transition support is provided with a fourth mounting hole corresponding to the third mounting hole, and the transition support is installed and fixed on the fan guard net through cooperation of the third mounting hole, the fourth mounting hole and a second bolt. The bolt and the mounting hole are used for installation and removal of the hydraulic motor, and a gasket can be used for installation.
[0011] Further, the fan guard net is composed of at least 16 bent round steel beams, a steel plate with a thickness not less than 10 mm is welded at the center of the fan guard net, and the driver is installed and fixed on the steel plate. The 16 bent round steel beams can be divided into eight groups to form a main structure frame of the fan guard net, and then the steel plate is installed at the center,
[0012] The overall structure is more stable and has higher structural strength.
[0013] By adopting the technical scheme, the heat dissipator has the following beneficial effects:
[0014] (1) The heat dissipator is fixed on one side of the bulldozer front hood, the fan guard net is installed on the other side of the bulldozer front hood, the fan is installed between the fan guard net and the heat dissipator, the driver for driving the fan to rotate is installed on the fan guard net, and the structure is simple and no additional mounting support is needed;
[0015] (2) The driver is a hydraulic motor, which is small in size, high in rotating speed and good in heat dissipation effect;
[0016] (3) increase the transition support on the fan guard, facilitate the installation of the hydraulic motor, the fan can be installed close to the radiator, improve the heat dissipation effect; BRIEF DESCRIPTION OF DRAWINGS
