Description

Technical Field

[0001] The present invention relates to the technical field of coolers, and in particular to an energy-saving double-circulation cooler. Background Art

[0002] In the field of industrial production, the cooling of compressed air is a key link in ensuring the stable operation of equipment and product quality. Most traditional coolers use a single cooling circulation system, in which a water pump drives the cooling water to exchange heat with the high-temperature, high-pressure compressed air in a heat exchanger to achieve the cooling of the compressed air. However, this traditional cooler has obvious energy consumption problems. The continuous operation of the water pump consumes a large amount of electricity, and the cooling water only relies on the heat exchanger for cooling once. When it enters the cooling water tank, it consumes more energy to cool it again, resulting in high overall operating costs. To address energy consumption, some existing coolers have implemented energy-saving measures, such as optimizing the heat exchanger structure or adding cooling fans to aid cooling. However, these improvements are either complex and costly, or require additional drive units. These improvements not only fail to fundamentally reduce energy consumption but also increase equipment complexity and failure rates. Therefore, how to fully utilize the energy in the cooling process, minimize the use of additional power units, and reduce cooling water tank energy consumption while maintaining heat exchange efficiency has become a pressing issue.

[0018] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0019] Reference Figures 1-8 As shown, the energy-saving dual-circulation cooler described in the present invention includes a shell 1, a main cooling mechanism 2 arranged in the shell 1, and an auxiliary cooling mechanism 3 arranged in the shell 1. The main cooling mechanism 2 includes a heat exchanger 21 arranged in the shell 1, a cooling water tank 22 connected to the heat exchanger 21, and a water pump 23 arranged in the shell 1 and transporting cooling water to the heat exchanger 21; the auxiliary cooling mechanism 3 includes a water containing chamber 31 connected to the heat exchanger 21, an impeller 32 rotatably arranged in the water containing chamber 31, a first rotating shaft 33 fixed on the impeller 32, an acceleration component 34 fixed on the rotating shaft, a second rotating shaft 35 fixed on the acceleration component 34, a plurality of blades 36 fixed on the second rotating shaft 35, a pre-cooling chamber 37 fixed on the shell 1, and a pre-cooling water pipe 38 connected to the water containing chamber 31 and fixed in the pre-cooling chamber 37.

[0020] Specifically, the acceleration assembly 34 includes a first large gear 341 fixed on the first rotating shaft 33, a first small gear 342 rotatably provided on the outer shell 1 and meshing with the first large gear 341, a second large gear 343 coaxially arranged with the first small gear 342, and a second small gear 344 rotatably provided on the outer shell 1 and meshing with the second large gear 343; the second small gear 344 is fixed on the second rotating shaft 35.

[0021] The high-temperature and high-pressure compressed air first passes through the heat exchanger 21. The high-temperature cooling water after heat exchange flows into the water holding chamber 31. The residual kinetic energy of the impeller 32 drives the rotation of the impeller 32, converting the kinetic energy of the water that should have been wasted into mechanical energy, thereby driving the first large gear 341 to rotate, and the first small gear 342 to rotate accordingly. This is the first acceleration. The second large gear 343 coaxial with the first small gear 342 rotates, thereby driving the second small gear 344 meshed with it to rotate. This is the second acceleration. After two accelerations, the speed of the second rotating shaft 35 is greater than the speed of the impeller 32, so that the multiple blades 36 obtain a rotational force far higher than the water flow speed, greatly enhancing the airflow intensity in the pre-cooling chamber 37. The multiple blades 36 rotate in the pre-cooling chamber 37, and the water flows in the pre-cooling water pipe 38. After passing through the pre-cooling chamber 37, the wind generated by the rotation of the multiple blades 36 initially cools the water flow in the pre-cooling water pipe 38, thereby reducing the subsequent refrigeration power consumption required by the cooling water tank 22 to maintain a low temperature. By using this cooler, the auxiliary cooling mechanism 3 consumes zero additional energy, but significantly reduces the system load of the main cooling mechanism 2, thereby improving the overall energy saving rate.

[0022] Specifically, the heat exchanger 21 includes a box body 211, an upper exchange layer 212 provided in the box body 211, a lower exchange layer 213 provided in the box body 211, a curved pipe 214 fixed in the box body 211 for conveying compressed air, an air inlet pipe 215 fixed on the box body 211 and connected to the curved pipe 214, an air outlet pipe 216 provided on the box body 211 and connected to the curved pipe 214, a drainage chamber 217 provided in the box body 211 and respectively connected to the upper exchange layer 212 and the lower exchange layer 213, a drainage pipe 218 provided on the drainage chamber 217 and connected to the water holding chamber 31, and a water supply component 219 fixed outside the box body 211 and for conveying cooling water to the upper exchange layer 212 and the lower exchange layer 213, respectively.

[0023] The water delivery component 219 delivers cooling water to the upper exchange layer 212 and the lower exchange layer 213 respectively, and the elbow 214 runs through the upper exchange layer 212 and the lower exchange layer 213. The compressed air undergoes two heat exchanges in the upper exchange layer 212 and the lower exchange layer 213, thereby improving the heat exchange efficiency.

[0024] Specifically, the water supply assembly 219 includes a cooling water pipe 2191 connected to the water pump 23, a regulating chamber 2192 fixedly arranged on the water inlet pipe, an upper water inlet pipe 2193 fixedly arranged on the regulating chamber 2192 for supplying water to the upper exchange layer 212, a lower water inlet pipe 2194 fixedly arranged on the regulating chamber 2192 for supplying water to the downward exchange layer 213, a stopper 2195 movably arranged in the regulating chamber 2192, a moving rod 2196 movably arranged in the air inlet pipe 215, a circular plate 2197 fixedly arranged on the moving rod 2196, and a return spring 2198 with its two ends respectively fixed on the air inlet pipe 215 and the circular plate 2197.

[0025] When the pressure of the compressed air is high, it will push the moving rod 2196 in the air inlet pipe 215. The other end of the moving rod 2196 is fixed on the stop block 2195. The moving rod 2196 drives the stop block 2195 to move downward. In the same time, more cooling water enters the upper cooling layer and the lower cooling layer to ensure normal heat exchange. When the pressure of the compressed air decreases, the return spring 2198 will drive the moving rod 2196 to move upward, and then move the stop rod upward to reduce the entry of cooling water. The water supply component 219 can adaptively adjust the amount of cooling water inlet, saving cooling water and reducing energy consumption while ensuring the heat exchange effect.

[0026] Specifically, the heat exchanger 21 also includes a stirring device; the stirring device includes a motor 220 fixed on the box body 211, a third rotating shaft 221 fixed at the output end of the motor 220, a limiting rod 222 fixed at one end of the third rotating shaft 221, a rotating rod 223 rotatably arranged in the box body 211, a limiting groove 224 provided in the rotating rod 223, and a stirring plate 225 fixed on the rotating rod 223; the third rotating shaft 221 is rotatably arranged on the box body 211.

[0027] The motor 220 starts, driving the third rotating shaft 221 to rotate, and then driving the limiting rod 222 to rotate. The limiting rod 222 moves in the limiting groove 224, driving the rotating rod 223 to swing up and down, and the stirring plate 225 to swing, disturbing the cooling water, eliminating water temperature stratification, and preventing local water temperature from being too high and affecting the heat exchange effect.

[0028] Specifically, an air duct 39 is fixedly provided on the pre-cooling chamber 37 ; a turbine expander 40 is fixedly provided at one end of the air duct 39 ; the turbine expander 40 is used to supply power to the motor 220 .

[0029] The wind generated by the rotation of the multiple blades 36 not only pre-cools the water after heat exchange, but also enters the turbine expander 40 through the air duct 39, generating electricity, which can be used to power the motor 220 in the stirring device, forming a closed loop of "waste energy generation and self-power supply". The turbine expander 40 is existing technology and will not be described in detail.

[0030] To sum up, this energy-saving dual-circulation cooler, through the coordinated work of the main cooling mechanism 2 and the auxiliary cooling mechanism 3, innovatively converts and recycles the kinetic energy of the cooling water in multiple stages on the basis of the main cooling mechanism 2 utilizing the cooling water circulation to complete the core heat exchange task and ensure the heat exchange efficiency. It not only reduces the energy consumption of the cooling water tank 22, but also realizes power supply to other components through energy generation, forming a unique energy recovery cycle mode, realizing the cascade utilization of internal energy, converting waste kinetic energy into effective cold source and electricity, and reducing overall energy consumption.
