Description

Technical Field

[0001] The utility model relates to the technical field of water chillers, in particular to a box-type industrial water chiller. Background Art

[0002] When the chiller is in use, a lot of dust is often deposited on the heat exchange tubes inside. The dust deposition will cause the surface of the heat exchange tubes to be closed, greatly reducing the heat exchange efficiency, so the dust needs to be processed and cleaned. At present, the dust is generally cleaned manually. On the one hand, manual cleaning wastes time and manpower. On the other hand, the surface temperature of the heat exchange tubes is high. When cleaning manually, it is easy to get burned, causing harm to the workers.

A conducting pipe is fixedly installed on the upper surface of the main body, and the top of the conducting pipe is fixedly connected to the three-way solenoid valve, and the three-way solenoid valve is fixedly connected to a first water inlet pipe and a compressed air pipe. The bottom end of the conducting pipe penetrates the upper surface of the main body and extends into the interior of the main body. A plurality of nozzles are evenly fixedly installed on the conducting pipe. By setting a cleaning device, the cleaning of dust prevents the surface of the heat exchange tube from being covered with dust, thereby avoiding the problem of a significant decrease in heat exchange rate due to dust coverage.

However, in actual use, the use of compressor refrigeration often has the problem of refrigeration delay. When the compressor starts to work, it takes a period of time to pressurize before an effective refrigeration effect can be achieved. Utility Model Content

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0025] Example 1: Please refer to Figure 1-4The utility model provides a technical solution: a box-type industrial water chiller, comprising a shell 1 and a cover plate 2 arranged thereon, a water inlet pipe 4 and a water outlet pipe 8 are arranged on the side of the shell 1, a connecting ring 3 is arranged on the water inlet pipe 4 and the water outlet pipe 8, a heat dissipation component 11 is arranged in the shell 1, the water inlet pipe 4 is provided with a branch pipe 12 through a control valve 9 and a filter 10, and the branch pipe 12 is located directly above the heat dissipation component 11, and is used to ensure stable water flow connection and prevent leakage;

[0026] The shell 1 is provided with an air inlet fan 7, the cover plate 2 is provided with an air inlet window 5, the top of the shell 1 is provided with an air outlet window 6, the heat dissipation component 11 includes a blower 1101, and a heat dissipation shell 1103 is provided on the side of the blower 1101 through a connecting piece 1102 for dissipating heat and cooling the water flow.

[0027] The heat dissipation component 11 includes multiple groups of narrow tubes 1104, which are arranged inside the heat dissipation shell 1103. The multiple groups of narrow tubes 1104 are conical in shape, and the ends of the multiple groups of narrow tubes 1104 with smaller diameters are facing directly upward. The branch pipe 12 is provided with multiple groups of parallel connecting tubes, and the multiple groups of connecting tubes are located at the top of the heat dissipation component 11. One side of the branch pipe 12 is connected to the filter 10, and the other end of the branch pipe 12 is connected to the water outlet pipe 8.

[0028] The multiple groups of air inlet fans 7 are symmetrically distributed on both sides of the air outlet window 6. A guide pipe is arranged on the bottom of the air outlet window 6, and the guide pipe is arranged directly above the branch pipe 12. Filters are arranged on the air inlet window 5 and the air outlet window 6. The air inlet window 5 is detachably connected to the cover plate 2, and the air outlet window 6 is detachably connected to the shell 1. A seal is arranged on the cover plate 2, and the seal is arranged at the connecting seam between the shell 1 and the cover plate 2. An air pressure pipe is arranged on the blower 1101, and the air pressure pipe is connected to the connecting piece 1102, and the connecting piece 1102 is conical.

[0029] This device can effectively improve the timeliness of the water flow cooling effect. Compared with traditional devices, this device uses narrow tube air cooling to achieve timeliness and stability of cooling, and adjusts the cooling effect by adjusting the size of the narrow tube air outlet, thereby ensuring the stability of the actual use of the device.

[0030] When the device is in working state, the structure of the connecting ring 3 can facilitate the combined connection of the water inlet pipe 4 and the water outlet pipe 8, thereby ensuring the docking stability of the device and preventing the device from leaking. When water flows through the inside of the device, the blower 1101 starts to start. At this time, the blower 1101 sucks air inward from the position of the air inlet window 5 on the cover plate 2 to form an airflow. The air is pressurized by the blower 1101 and enters the inside of the connecting piece 1102, and then enters the inside of the heat dissipation shell 1103 through the inside of the connecting piece 1102. The heat dissipation shell 1103 can guide the airflow into multiple groups of narrow tubes 1104. The structure of the narrow tube 1104 with a narrow top and a wide bottom can accelerate the airflow after the airflow enters the inside of the narrow tube 1104 from the bottom, thereby forming a narrow tube effect. The narrow tube effect can reduce the temperature of the airflow passing through the inside of the narrow tube 1104 and increase the flow rate, thereby achieving the effect of cooling the upper branch pipe 12.

[0031] When the blower 1101 is turned on, the multiple groups of air inlet fans 7 on the top of the shell 1 start to work, and the air inlet fans 7 are used to blow heat into the shell 1, thereby forming an airflow toward the inside of the shell 1 on both sides of the top air outlet window 6. Since the branch pipe 12 and the heat dissipation component 11 are located at the center of the shell 1, the airflow from the narrow tube 1104 that has been heated through the branch pipe 12 flows out from the heat dissipation shell 1103, and then moves upward driven by the airflow from the air inlet fans 7 entering from both sides, and finally discharges the high-temperature airflow from the top air outlet window 6, thereby avoiding heat accumulation inside the shell 1. The symmetrical structure of the air inlet fans 7 can generate a vortex effect inside the shell 1, so that the air pressure on both sides of the shell 1 is larger, and the air pressure at the center of the shell 1 is smaller, thereby utilizing the pressure difference to push the high-temperature airflow toward the air outlet window 6 at the top of the center, thereby improving the airflow exchange efficiency inside the shell 1. The structure of the branch pipe 12 can increase the contact area between the water flow and the low-temperature airflow.

[0032] When the cooling effect of the narrow tube 1104 needs to be adjusted, rotating the threaded rod 1106 can make the adjustment blocking plate 1107 slide relative to the heat dissipation shell 1103. Since corresponding through holes are provided on the top of the heat dissipation shell 1103 and the adjustment blocking plate 1107, when the adjustment blocking plate 1107 is accurately aligned with the through hole on the top of the heat dissipation shell 1103, the narrow tube 1104 is open to the maximum and the cooling effect is the lowest. When the adjustment blocking plate 1107 slides, the through holes are misaligned with each other, thereby reducing the common passing space of the through holes, thereby reducing the through hole at the air outlet end of the narrow tube 1104, thereby increasing the degree of the narrow tube 1104 and achieving an improved cooling effect. Therefore, the device can adjust the opening of the air outlet end of the narrow tube 1104 to achieve the effect of adjusting the cooling effect of the device.

[0033] Embodiment 2: Figure 1-4 As shown, a box-type industrial water chiller disclosed in Example 2 of the utility model has a structure that is basically the same as that in Example 1, except that the heat dissipation component 11 includes a threaded bracket 1105, a threaded rod 1106 is threadedly arranged on the threaded bracket 1105, an adjustment blocking plate 1107 is rotatably arranged on the threaded rod 1106, a plurality of groups of through holes are arranged on the top of the heat dissipation shell 1103, the adjustment blocking plate 1107 is provided with through holes corresponding to the through holes on the top of the heat dissipation shell 1103, and the adjustment blocking plate 1107 is slidably connected to the top of the heat dissipation shell 1103.

[0034] By adjusting the structure of the blocking plate 1107 , the size of the through hole at the top air outlet of the heat dissipation housing 1103 can be controlled, and the structure of the threaded rod 1106 can prevent the position of the adjusting blocking plate 1107 from accidentally sliding.
