Description

Technical Field

[0001] This utility model belongs to the field of engine cooling technology, and in particular relates to a water-cooled radiator for diesel engines. Background Technology

[0002] In stationary operating scenarios such as petroleum engineering, diesel engines need to run continuously for long periods of time, making the efficiency of their cooling systems crucial. Traditional air-cooled radiators mostly adopt an open fin structure, and their cooling efficiency relies on natural air convection or forced airflow generated by a fan. However, when the engine is stationary, such radiators have significant limitations: the airflow time over the fins is short and the path is not fixed, resulting in insufficient heat exchange and limited cooling effect of the coolant. Especially under high temperature or high load conditions, insufficient heat dissipation can easily lead to engine overheating, affecting operational safety and lifespan. Existing technologies lack efficient and compact cooling solutions for stationary engines.

[0003] To address these issues, we provide a water-cooled radiator for diesel engines. Utility Model Content

[0004] The purpose of this utility model is to provide a water-cooled radiator for diesel engines. By fixing an outer sleeve at one end of a fan, a set of water-cooled pipes are fitted inside the outer sleeve. The adjacent ends of each adjacent water-cooled pipe are connected, and the water-cooled pipes are connected to the water-cooling chamber of the diesel engine through a pipeline. The fan blows air into the outer sleeve, so that the airflow can fully dissipate heat from the water-cooled pipes inside the outer sleeve, thereby ensuring that the cooling water in the water-cooled pipes can be fully cooled.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a water-cooled radiator for a diesel engine, including a fan, a set of water-cooled pipes and an outer sleeve. The outer sleeve is fixedly installed on one side of the fan outlet. Each water-cooled pipe is sleeved inside the outer sleeve.

[0007] A further feature of this invention is that a diversion water injection head is provided inside the outer sleeve, and the diversion water injection head is located at the end of the water-cooling pipe assembly near the fan. One side of the diversion water injection head is connected to a pipe that penetrates the wall of the outer sleeve.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1

[0021] Please see Figures 1 to 5 This utility model is a water-cooled radiator for a diesel engine, including a fan 1, a set of water-cooled pipes 2, and an outer sleeve 3. The outer sleeve 3 is fixedly installed on one side of the air outlet of the fan 1. Each water-cooled pipe 2 is sleeved inside the outer sleeve 3, and the pipe axis of the water-cooled pipe 2 is parallel to the pipe axis of the outer sleeve 3. The water-cooled pipes 2 are arranged in a ring array, and one end of every two adjacent water-cooled pipes 2 is connected by a U-shaped bend. One end of two water-cooled pipes 2 extends out of the outer sleeve 3 through a pipe. The fan 1 concentrates the airflow into the outer sleeve 3, forcing the airflow to continuously flow over the surface of the ring array of water-cooled pipes 2, significantly extending the heat exchange time, efficiently cooling the coolant circulating inside the water-cooled pipes 2, ensuring that the heat dissipation requirements of the diesel engine are met during stationary operation, effectively preventing engine overheating, and improving operational reliability and lifespan.

[0022] Specifically, an inner support tube 301 is provided inside the outer sleeve 3. The axis of the inner support tube 301 is parallel to the axis of the outer sleeve 3. A set of heat-conducting plates 301a are fixedly arranged in a vertical circumferential array on the outer side wall of the inner support tube 301. The length direction of the heat-conducting plates 301a is parallel to the axis of the inner support tube 301. A sleeve 301a-1 is fixedly provided in the middle section of the heat-conducting plate 301a. Each sleeve 301a-1 is fixedly sleeved on the outside of each water-cooling pipe 2. The inner support tube 301 and the heat-conducting plate 301a provide a solid support for the water-cooling pipe 2 and prevent structural deformation caused by vibration. At the same time, the heat-conducting plate 301a can quickly absorb the heat of the water-cooling pipe 2 and diffuse it to a larger surface area, which significantly enhances the heat dissipation efficiency. The sleeve 301a-1 ensures close thermal contact between the water-cooling pipe 2 and the heat-conducting plate 301a, optimizes the heat conduction path, and improves the overall heat dissipation performance and structural stability.

[0023] Furthermore, a diversion water inlet head 302 is installed inside the outer casing 3. The diversion water inlet head 302 is located at the end of the water cooling pipe group 2 near the fan 1. One side of the diversion water inlet head 302 is connected to a pipe that penetrates the wall of the outer casing 3. A set of water inlet pipes 302a are connected in a circumferential array on the outer wall of the diversion water inlet head 302. A water mist nozzle 302a-1 is installed at the end of the water inlet pipe 302a away from the diversion water inlet head 302. The water outlet end of the water mist nozzle 302a-1 faces the water cooling pipe. The lower side wall of the outer sleeve 3 of the pipe 2 is provided with a drainage groove 303; the water injection head 302 can evenly distribute the external cooling water to each water injection pipe 302a, and spray fine water mist onto the surface of the water-cooled pipe 2 through the water mist nozzle 302a-1. The water mist absorbs a large amount of heat by evaporation, achieving efficient evaporative cooling and greatly improving heat dissipation capacity. Especially under high temperature and high load conditions, it can quickly reduce the temperature of the coolant. The drainage groove 303 ensures that excess water is discharged in time to prevent internal water accumulation.

[0024] Furthermore, a cone cap 301b is fixed at one end of the inner support tube 301 near the diversion water injection head 302, with the pointed end of the cone cap 301b facing the diversion water injection head 302; the cone cap 301b can effectively guide the airflow smoothly into the annular space between the inner support tube 301 and the outer sleeve 3, reduce airflow impact and turbulence loss, ensure that the airflow is evenly distributed to the surface of all water cooling tubes 2 and heat conduction plate 301a, and improve heat dissipation uniformity and airflow utilization efficiency.

[0025] Furthermore, an inner support sleeve 301c is fixedly sleeved inside the end of the inner support tube 301 away from the cone cap 301b. A set of side connecting arms 301c-1 is fixedly provided at one end of the inner support sleeve 301c. An inner support ring 301c-2 is fixedly provided at the end of the set of side connecting arms 301c-1 away from the inner support sleeve 301c. The inner support ring 301c-2 is fixedly sleeved on the inner wall of the outer sleeve 3. The inner support sleeve 301c provides rigid support for the inner support tube 301 through the side connecting arms 301c-1 and the inner support ring 301c-2, thereby enhancing the overall structural vibration resistance and concentricity.

[0026] Furthermore, an air inlet filter 101 is provided on the side of the fan 1 away from the outer casing 3, and a filter screen 304 is fixedly sleeved on the end of the outer casing 3 away from the fan 1. The air inlet filter 101 can efficiently filter dust, insects and other impurities in the air entering the fan 1, preventing pollutants from accumulating inside the radiator and blocking the air duct or reducing the heat dissipation effect. The filter screen 304 can block external debris from entering the outer casing 3, protect the water cooling pipe 2 and internal components from damage, reduce the cleaning frequency, and ensure that the radiator operates efficiently and reliably for a long time in a dusty environment.

[0027] The operation process of this embodiment is as follows: Fan 1 is started, and Fan 1 draws in filtered air from one side of the air intake filter 101 and concentrates the airflow into the outer sleeve 3; the airflow is guided by the cone cap 301b in the outer sleeve 3 and flows evenly over the surface of the annular array of water-cooling pipes 2, absorbing heat from the water-cooling pipes 2 and then being discharged from one end of the filter screen 304; the coolant flows in from one of the two water-cooling pipes 2 extending from the outer sleeve 3, circulates between the water-cooling pipes 2 through the U-shaped bend, and finally returns to the engine from the other water-cooling pipe 2, achieving continuous cooling. Continuous heat exchange; if the ambient temperature is high or the engine load increases, the diversion water head 302 can be activated to deliver cooling water through the water injection pipe 302a to the water mist nozzle 302a-1, spraying water mist onto the surface of the water-cooled pipe 2, using evaporation to absorb heat and enhance heat dissipation, and excess water is discharged from the drain trough 303; throughout the process, the inner support pipe 301 and the heat conduction plate 301a provide structural support and enhance heat dissipation, while the inner support sleeve 301c and the inner support ring 301c-2 maintain internal stability, ensuring that the radiator works efficiently and stably.
