Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, specifically relating to a heat dissipation system for a new energy electric excavator, and in particular a radiator and fan installation device that is easy to clean and maintain. Background Technology

[0002] New energy electric excavators are widely used due to their advantages such as zero emissions and low noise. However, during operation, the drive motor and motor controller generate a large amount of heat, requiring an efficient cooling system to ensure the normal operation of these core components. Because electric excavators need to carry large-capacity power batteries, the space on the upper platform is largely occupied, resulting in very limited space for radiator installation.

[0003] Currently, radiators are typically rigidly fixed to brackets with bolts. While this installation method is secure, it presents significant maintenance drawbacks: when dust, catkins, and other debris accumulate on the radiator fins and heat pipes, it severely impacts heat dissipation efficiency. In confined spaces, removing the bolts to clean the inside and outside of the radiator is extremely inconvenient, often leading to neglect by operators. Over time, this can cause overheating, affecting performance and lifespan. Summary of the Invention

[0004] The purpose of this invention is to provide a radiator for new energy electric excavators that is simple in structure and easy to open and close, so as to solve the problem of difficult cleaning of radiators in the prior art due to the compact installation space.

[0005] The technical solution of the present invention: A radiator and fan mounting device for a new energy electric excavator includes a radiator 2 and a fan 4, characterized in that: one end of the radiator 2 and its mounting bracket is hinged to the main support of the excavator via a first hinge 1, and the other end is detachably connected to the main support via a first locking device; the fan 4 is mounted on a fan mounting bracket 3, one end of the fan mounting bracket 3 is hinged to the mounting bracket of the radiator 2 via a second hinge, and the other end is detachably connected to the radiator 2 via a second locking device.

[0006] The first locking device and the second locking device are latches or bolts.

[0007] The fan mounting bracket 3 forms an air guide shroud structure.

[0008] When the first locking device is opened, the radiator 2 can rotate outward around the axis of the first hinge 1.

[0009] When the second locking device is opened, the fan mounting bracket 3, together with the fan 4 thereon, can rotate outward around the axis of the second hinge.

[0010] The beneficial effects of this invention are: 1. High ease of maintenance: There is no need to completely disassemble multiple bolts. The radiator and fan module can be flipped open by simply operating the locking device, which greatly reduces the difficulty and time of cleaning and encourages regular maintenance.

[0011] 2. Thorough cleaning: By opening the radiator bracket and fan bracket separately, you can clean both the inner and outer surfaces of the radiator without any blind spots, ensuring effective heat dissipation.

[0012] 3. Simple and reliable structure: With minimal additional cost and complexity, a clever installation method solves a major maintenance pain point in practical engineering. The hinge connection ensures stability during rotation and accurate repeatability.

[0013] 4. Good space adaptability: It is especially suitable for use in situations where the internal space of equipment such as new energy excavators is compact. Attached Figure Description

Figure 2 This is an example diagram of the present invention installed on a vehicle body. Figure 3 This is an example diagram of the radiator in the open state on the vehicle body in this utility model. Figure 4 This is an example diagram of the fan in the open state in this utility model. Detailed Implementation

[0015] Example 1: like Figure 1 and Figure 2 As shown, the device of this utility model mainly consists of a radiator mounting bracket, a radiator 2, a fan mounting bracket 3, and a fan 4. The radiator 2 is fixedly mounted on the radiator mounting bracket by bolts or clips. The right side of the radiator mounting bracket (taking the position shown in the figure as an example) is hinged to the main frame of the excavator through a first hinge 1; the left side is connected and fixed to the main frame by one or more bolts (or latches).

[0016] Fan 4 is mounted on fan mounting bracket 3, which also acts as an air guide to direct airflow through radiator 2. The right side of fan mounting bracket 3 is hinged to radiator mounting bracket via a second hinge; its left side is secured to radiator mounting bracket via quick-release latches (or bolts).

[0017] The cleaning process is as follows: Clean the inside of the radiator: See Figure 3When it is necessary to clean the fins on the inside of the radiator 2 (the side facing the inside of the vehicle body), simply loosen the bolts (or latches) on the left side of the radiator mounting bracket. At this time, the operator can pull the left side of the radiator mounting bracket outward, causing it to rotate around the first hinge 1 on the left side to open, thereby exposing the inner surface of the radiator 2 for easy blowing or rinsing.

[0018] Clean the outside of the radiator: See Figure 4 When it is necessary to clean the fins on the outside of the heatsink 2 (the side with the fan attached), simply open the latch on the left side of the fan mounting bracket 3. At this time, the fan mounting bracket 3, together with the fan 4, can be rotated to the right around the second hinge axis on its right side to open and expose the outer surface of the heatsink 2 for cleaning.

[0019] After cleaning, push the fan mounting bracket 3 and the heatsink mounting bracket back into their original positions and tighten the latches to restore the working state.

[0020] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model.
