Description

Technical Field

[0001] This utility model relates to the field of heat exchangers, and more particularly to coolers for engineering machinery. Background Technology

[0002] The machinery and equipment used in various construction projects, civil engineering projects, road construction, mining projects, and other engineering projects are collectively referred to as construction machinery. The core components of construction machinery, such as engines, hydraulic systems, and transmission systems, generate a large amount of heat during operation. If this heat cannot be dissipated effectively and in a timely manner, it can easily lead to component damage or malfunction. Therefore, heat exchangers are needed to cool these components.

[0003] Construction machinery typically operates in harsh environments surrounded by large amounts of mud, sand, and dust. When this mud, sand, and dust enter the heat exchanger, it can easily cause blockages. Furthermore, to protect components requiring cooling, such as the engine, hydraulic system, and transmission system, they are usually enclosed in a casing, and the heat exchanger is also located within this casing. This causes waste heat generated by the heat exchanger to accumulate inside the casing, which is detrimental to the normal operation of the equipment. To solve this problem, ventilation holes are usually made in the casing, directly opposite the heat exchanger's vents.

[0004] Currently, air-cooled plate-fin heat exchangers are a commonly used type of heat exchanger in construction machinery. Their structure is existing technology, featuring a cooling air inlet and outlet. Under normal operating conditions, the cooling air outlet of the air-cooled plate-fin heat exchanger faces the equipment's heat dissipation holes, and the cooled air is discharged by blowing air outwards. However, due to the harsh operating environment of construction machinery, mud and sand splashed from the ground can enter against the airflow from the heat dissipation holes, clogging the cooling air outlet of the heat exchanger and thus affecting its normal operation. Utility Model Content

[0005] To address the aforementioned technical problems, the purpose of this utility model is to provide a cooler for engineering machinery that can reduce the impact of mud and sand clogging the heat exchanger on normal heat exchange.

[0008] The cooler for engineering machinery provided by this utility model preferably has a heat dissipation window that can be detachably fixed inside the heat dissipation port.

[0009] The cooler for engineering machinery provided by this utility model preferably has several receiving grooves on the surface of the mudguard facing away from the cooling air outlet; several positioning blocks are fixed on the heat dissipation window; the positioning blocks can be inserted into the receiving grooves for fixation; the heat dissipation window can be fixed on the mudguard through the cooperation of the positioning blocks and the receiving grooves; after the heat dissipation window is fixed on the mudguard, the heat dissipation window completely covers the heat dissipation opening.

[0010] The cooler for engineering machinery provided by this utility model preferably has the mudguard plate facing the cooling air outlet recessed towards the heat dissipation port.

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. It should also be noted that the terminology used in this utility model is for describing specific implementations only and is not intended to limit the exemplary implementations according to this application.

[0018] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Therefore, the detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without inventive effort are within the protection scope of the present utility model.

[0019] Example 1:

[0020] The cooler for engineering machinery provided in Embodiment 1 of this utility model, such as Figures 1 to 2 As shown, it includes a heat exchange body 1 and a baffle 2; the heat exchange body 1 has a cooling air outlet 11; the baffle 2 is fixed on the heat exchange body 1; one side of the baffle 2 faces the cooling air outlet 11; there is a gap between the baffle 2 and the heat exchange body 1; a heat dissipation vent 21 is provided in the center of the baffle 2.

[0021] In actual operation, the cooler for construction machinery in this embodiment uses a heat exchanger body 1 to cool the coolant. The heat exchanger body 1 adopts a conventional air-cooled plate-fin heat exchanger, with the cooling air outlet 11 serving as its outlet. The air blown out is the air after heat exchange with the coolant inside the heat exchanger body 1. When the construction machinery operates in muddy areas, splashed mud and sand will fly towards the heat exchanger body 1, but most of the mud and sand will be blocked by the mudguard 2. Only a small amount of mud and sand can pass through the mudguard 2 through the heat dissipation port 21 and contact the heat exchanger body 1. Compared with the prior art where the cooling air outlet 11 of the heat exchanger body 1 is directly exposed, this embodiment greatly reduces the amount of mud and sand that may directly contact the heat exchanger body 1 through the blocking effect of the mudguard 2, effectively reducing the probability of mud and sand clogging the heat exchanger. At the same time, when there is no mud and sand interference, the cooled air after heat exchange can be discharged from the heat dissipation port 21, avoiding the accumulation of high-temperature cooling air inside the equipment and solving the problem in the prior art where heat accumulation inside the equipment affects the heat dissipation effect of other components that require heat dissipation.

[0022] The cooler for construction machinery provided in Embodiment 1 of this utility model solves the problem in the prior art that the heat exchanger of construction machinery is easily blocked by mud and sand, which affects the heat exchange effect. It can reduce the situation where the heat exchange is affected due to the blockage of the heat exchanger by mud and sand.

[0023] After a period of use, the heat dissipation window 3 will accumulate dirt and sand, requiring cleaning to ensure that cooling air can dissipate normally from the heat dissipation vent 21. In this embodiment, the heat dissipation window 3 is detachably fixed inside the heat dissipation vent 21. When the heat dissipation window 3 is fixed to the mudguard 2, it can completely block the heat dissipation vent 21. For ease of use, some spare heat dissipation windows 3 can be kept in the construction machinery. Workers do not need to clean the dirt and sand from other parts of the mudguard 2; they only need to replace the heat dissipation window 3 to ensure the unobstructed flow of the heat dissipation vent 21.

[0024] To facilitate the replacement of the heat dissipation window 3, in this embodiment, several receiving grooves 22 are provided on the surface of the mudguard 2 facing away from the cooling air outlet 11; several positioning blocks 31 are fixed on the heat dissipation window 3; the positioning blocks 31 can be inserted into the receiving grooves 22 for fixation; the heat dissipation window 3 can be fixed on the mudguard 2 through the cooperation of the positioning blocks 31 and the receiving grooves 22; after the heat dissipation window 3 is fixed on the mudguard 2, the heat dissipation window 3 completely covers the heat dissipation opening 21. The operator can achieve the connection and cooperation between the heat dissipation window 3 and the mudguard 2 through the cooperation of the positioning blocks 31 and the receiving grooves 22.

[0025] Considering that the cross-section of the cooling air outlet 11 is larger than that of the heat exchange vent 21, in this embodiment, to ensure that the cooling air can be smoothly discharged from the cooling air outlet 11, the surface of the baffle 2 facing the cooling air outlet 11 is recessed towards the heat exchange vent 21. The recessed surface on the baffle 2 can guide the cooling air blown out of the cooling air outlet 11, making the cooling air more inclined to flow out from the heat exchange vent 21. This not only reduces the amount of cooling air flowing into the equipment from the gap between the baffle 2 and the heat exchange body 1, reducing the accumulation of high-temperature cooling air inside the equipment, but also increases the wind speed at the heat exchange vent 21, helping the mud and sand adhering to the heat exchange window 3 to detach from the heat exchange window 3 and be discharged to the outside of the equipment.

[0026] As a preferred embodiment, in this case, the mudguard 2 and the heat exchange body 1 are connected by several springs 4; the extension and retraction direction of the springs 4 is perpendicular to the plane of the cooling air outlet 11. The mudguard 2 and the heat exchange body 1 are elastically connected only by multiple sets of springs 4, and the extension and retraction direction of the springs 4 is orthogonal to the plane of the cooling air outlet 11. This structural design has dual advantages: on the one hand, the elastic buffering effect of the springs 4 can effectively alleviate the pressure load generated by the continuous action of the cooling air, preventing structural separation between the mudguard 2 and the heat exchange body 1; on the other hand, utilizing the elastic deformation characteristics of the springs 4, the mudguard 2 can dynamically oscillate slightly relative to the heat exchange body 1, causing the mud and sand particles attached to the mudguard 2 and the heat dissipation window 3 to fall off due to inertia, significantly slowing down the clogging rate of the heat dissipation window 3. By introducing this elastic connection mechanism, this embodiment achieves the self-cleaning function of the equipment while ensuring structural stability, effectively improving the environmental adaptability and long-term operational reliability of the heat exchange device.

[0027] In summary, this utility model provides a cooler for construction machinery, relating to the field of heat exchangers, including a heat exchange body and a mudguard; the heat exchange body has a cooling air outlet; the mudguard is fixed to the heat exchange body; one side of the mudguard faces the cooling air outlet; a gap is left between the mudguard and the cooling air outlet; a heat dissipation vent is provided at the center of the mudguard surface. The cooler for construction machinery provided by this utility model solves the problem in the prior art where heat exchangers in construction machinery are easily clogged by mud and sand, affecting the heat exchange effect, and can reduce the situation where mud and sand blockage of the heat exchanger affects the normal operation of heat exchange.
