[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0029] This application provides a water tank radiator, an engine, and a fracturing truck, which can solve the technical problems of the traditional water tank radiator having a messy and bulky arrangement of multiple cooling units, making the replacement or maintenance of the radiator very complicated, and the heat dissipation process not achieving the expected effect.

[0030] Firstly, such as Figure 1 , Figure 2 and Figure 3 As shown, this application embodiment provides a water tank radiator, which includes: a cubic frame 1, a filter screen 1 installed at the bottom of the cubic frame 1, and a cooling fan 2 installed at the top of the cubic frame 1; four cooling units 3, which correspond one-to-one with the four sides of the cubic frame 1 and are installed on the corresponding side of the cubic frame 1. The cooling units 3 have air inlet holes 5 reserved near the edge of the cubic frame 1, and a filter screen 2 is installed at the air inlet holes 5.

[0031] In this embodiment, a cubic frame 1 is used as the core support structure. A filter screen 1 (not shown in the figure) is configured at the bottom for preliminary filtration of dust and impurities, and a cooling fan is integrated at the top to form an air circulation system. This design integrates the heat dissipation components inside the cubic frame 1, optimizing space utilization and reducing the clutter of the traditional dispersed layout of multiple cooling units 3. The four cooling units 3 are installed on the four sides of the cubic frame 1, and each cooling unit has an air inlet vent 5 with a filter screen 2 (not shown in the figure) near the edge of the cubic frame 1. This layout uses multi-directional air intake channels to enhance air circulation efficiency, while facilitating independent disassembly and maintenance, avoiding the waste of resources caused by overall replacement. Filter screen 1 and filter screen 2 are respectively set at the bottom of the cubic frame 1 and at the air inlet vent 5 to form a filtration mechanism to reduce the risk of dust blockage. The air inlet vent 5 are distributed along the edges, working with the top cooling fan 2 to form a bottom-up directional airflow, improving the heat exchange efficiency between the heat dissipation medium and the air.

[0032] Furthermore, the cooling unit 3 and the cubic frame 1 adopt a split connection structure (such as snap-fit ​​or plug-in), which can be quickly disassembled and assembled through components such as connecting blocks and sockets, significantly reducing maintenance complexity; in addition, the filter screen adopts a detachable installation method, which is convenient for cleaning or replacement.

[0033] In conjunction with the first aspect, in one embodiment, the water tank radiator further includes two water tanks 4 and a water pump connected to the water tanks 4. The two water tanks 4 are distributed at both ends of the cooling fan 2 and are both installed on the top of the cubic frame 1. Each water tank 4 is connected to the cooling unit 3 on the same side.

[0034] In this embodiment, two water tanks 4 are symmetrically installed at both ends of the cooling fan 2 on the top of the cubic frame 1. The water tanks 4 are connected to the water pump through pipes to form a circulating water path. Each water tank 4 is connected to the cooling unit 3 on the same side through an independent pipe to form a split water cooling circulation system. The two water tanks 4 are distributed on both sides of the cooling fan 2 and are arranged in a compact manner through the top space of the cubic frame 1 to avoid the pipes from crossing and tangling. The water pump drives the coolant from the water tank 4 to the cooling unit 3 for heat exchange and then back to the original location.

[0035] In conjunction with the first aspect, in one embodiment, the water tank radiator further includes: a water level sensor installed inside the water tank 4, an alarm and a controller, the controller being signal-connected to the water level sensor and the alarm, and the controller being used to activate the alarm to issue an alarm when the water level sensor detects that the water level in the water tank 4 has dropped to a set water level value.

[0036] In this embodiment, a water level sensor is installed inside the water tank 4 and is connected to the controller via a signal line. The controller is also linked with the alarm. When the water level sensor detects that the water level in the water tank 4 has dropped to a preset threshold (such as 15% of the total capacity), the controller immediately triggers the alarm to issue an audible and visual alarm and can transmit the status information to an external monitoring terminal through an expansion interface.

[0037] For example, the water level sensor is installed on the inner wall of the water tank 4 at a distance of more than 20cm from the bottom to avoid interference from bottom sediments on the detection accuracy. At the same time, it is fixed by a sealing flange to ensure waterproofing. Capacitive or pressure sensors can be used. The sensor lead is led out to the controller through a waterproof sleeve. The lead length is ≤1.5m to prevent signal attenuation.

[0038] In conjunction with the first aspect, in one embodiment, each edge of the cubic frame 1 is slidably connected to an elastic telescopic component 6, and the opposite side walls of the cooling unit 3 are provided with snap-fit ​​grooves; when the elastic telescopic component 6 slides along the height direction of the cubic frame 1 to the corresponding snap-fit ​​groove, the elastic telescopic component 6 is inserted into the corresponding snap-fit ​​groove by its own elastic force.

[0039] In this embodiment, the elastic telescopic component 6 is slidably connected to the edge of the cubic frame 1 via a slide rail and is equipped with a spring inside. When it slides along the height direction of the cubic frame 1 to the corresponding position of the snap-fit ​​groove on both sides of the cooling unit 3, the end of the elastic telescopic component 6 is driven by the elastic force to automatically insert into the snap-fit ​​groove, thereby realizing the lateral positioning of the cooling unit 3.

[0040] Furthermore, the slide rail of the elastic telescopic component 6 adopts a dovetail groove structure, which cooperates with the guide groove of the frame edge to restrict the elastic telescopic component 6 to move only in the vertical direction, avoiding horizontal offset that could lead to jamming failure.

[0041] Furthermore, the inner wall of the snap-fit ​​groove of the cooling unit 3 is provided with a wear-resistant bushing, which forms a self-aligning contact with the tapered snap-fit ​​joint of the elastic telescopic component 6, reducing the installation accuracy requirements.

[0042] Furthermore, the elastic telescopic component 6 is equipped with a manual unlocking lever. Pressing down the lever compresses the spring, causing the snap-fit ​​connector to exit the snap-fit ​​slot, thus enabling the quick disassembly of the cooling unit 3.

[0043] In conjunction with the first aspect, in one embodiment, a rubber air guide strip is fixed to the inner side of the filter screen 2, and along the height direction of the cubic frame 1, the rubber air guide strip gradually approaches the cooling fan 2.

[0044] In this embodiment, a rubber air guide strip is fixed on the inner side of the filter screen 2. It is distributed gradually along the height direction of the cubic frame 1 and converges at the end towards the axis of the cooling fan 2 to form an airflow directional channel.

[0045] For example, the rubber air guide strip is obliquely welded to the inner side of the filter screen 2 at an angle of 15° to 30°. As the height increases, the distance between the rubber air guide strip and the cooling fan 2 gradually decreases, guiding the airflow from bottom to top to concentrate on the cooling fan 2. The rubber air guide strip accelerates the airflow along the height direction of the cubic frame 1, forming a low-pressure area at the air inlet of the cooling fan 2, increasing the throughput per unit time, and reducing turbulence noise.

[0046] Furthermore, the rubber air guide strip is made of silicone rubber that is resistant to 120℃, and the surface is coated with an anti-static coating to reduce dust adsorption.

[0047] In conjunction with the first aspect, in one embodiment, filter screen one or filter screen two includes an outer metal coarse filter screen and an inner activated carbon fiber fine filter screen, both of which can be detachably fixed to the cubic frame 1.

[0048] In this embodiment, the outer metal coarse filter can be formed by welding 304 stainless steel perforated plate and embedded into the mounting slot of the cubic frame 1 through the dovetail groove slide rail, which first intercepts particles ≥1mm (such as mud, sand, iron filings); the inner activated carbon fiber fine filter has a folded honeycomb structure and is locked with the positioning post of the cubic frame 1 by rotating buckle, so as to achieve adsorption of 0.1-0.5μm particles.

[0049] In conjunction with the first aspect, in one embodiment, the water tank radiator further includes a temperature sensor and a controller. The temperature sensor is mounted on a bracket in the central area inside the cubic frame 1, and the controller is signal-connected to the temperature sensor and the cooling fan 2. The controller is used to control the increase of the speed of the cooling fan 2 when the temperature sensor detects that the temperature has reached the set temperature value.

[0050] In this embodiment, the temperature sensor is fixed to the geometric center of the cubic frame 1 by a stainless steel bracket. This layout can collect heat exchange data of multi-directional airflow in the heat dissipation cavity in a balanced manner, avoiding local temperature misjudgment. The controller has a built-in PID algorithm to dynamically adjust the PWM drive signal of the cooling fan 2 according to the real-time data of the temperature sensor. When the monitored temperature is lower than the set threshold (e.g., 80°C), the fan base speed (1200 rpm) is maintained to balance energy consumption. For every 5°C increase in temperature, the speed is gradually increased to the highest level (2400 rpm).

[0051] In conjunction with the first aspect, in one embodiment, the cooling unit 3 includes a cylinder liner water cooler, an intercooler, a fuel cooler, a torque converter oil cooler, a large pump oil cooler, or a hydraulic oil cooler.

[0052] In this embodiment, the cooling unit 3 includes a cylinder liner water cooler, an intercooler, a fuel cooler, a torque converter oil cooler, a large pump oil cooler, or a hydraulic oil cooler. Each cooler is modularly integrated into the cooling cavity of the cubic frame 1.

[0053] Secondly, this application provides an engine comprising: a cubic frame 1, a filter screen 1 installed at the bottom of the cubic frame 1, and a cooling fan 2 installed at the top of the cubic frame 1; four cooling units 3 connected to the engine, the four cooling units 3 corresponding one-to-one with the four sides of the cubic frame 1 and installed on the corresponding side of the cubic frame 1, and the cooling units 3 having air inlet holes 5 reserved near the edges of the cubic frame 1, and a filter screen 2 installed at the air inlet holes 5.

[0054] In this embodiment, a cubic frame 1 is used as the core support structure. A filter screen 1 (not shown in the figure) is configured at the bottom for preliminary filtration of dust and impurities, and a cooling fan is integrated at the top to form an air circulation system. This design integrates the heat dissipation components inside the cubic frame 1, optimizing space utilization and reducing the clutter of the traditional dispersed layout of multiple cooling units 3. The four cooling units 3 are installed on the four sides of the cubic frame 1, and each unit has an air inlet vent 5 with a filter screen 2 (not shown in the figure) near the edge of the cubic frame 1. This layout uses multi-directional air intake channels to enhance air circulation efficiency, while facilitating independent disassembly and maintenance, avoiding the waste of resources caused by overall replacement. Filter screen 1 and filter screen 2 are respectively set at the bottom of the cubic frame 1 and at the air inlet vent 5 to form a filtration mechanism to reduce the risk of dust blockage. The air inlet vent 5 are distributed along the edges, working with the top cooling fan 2 to form a bottom-up directional airflow, improving the heat exchange efficiency between the heat dissipation medium and the air.
