Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooling equipment technology, and in particular to a high-precision constant temperature cooling device. Background Technology
[0002] Cooling equipment is a machine that achieves a cooling effect through vapor compression or absorption circulation, primarily used to lower or maintain a certain temperature range. They are widely used in various industrial and commercial sectors.
[0003] Existing cooling equipment uses a refrigeration system to cool water and delivers the low-temperature cooling water to the equipment that needs cooling to achieve a constant temperature, constant flow, and constant pressure cooling effect. It removes heat through a circulating water system to achieve the purpose of cooling the equipment. Traditional cooling equipment is equipped with a single compressor and evaporator. This makes it difficult for a single evaporator to evenly cover a large space or multiple areas, which may result in local overheating or overcooling and make it impossible to accurately control the temperature. Moreover, a single compressor cannot flexibly adjust its output power according to load changes, which may lead to low efficiency at high loads and frequent start-stop at low loads, increasing energy consumption and equipment wear.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figure 1-7 A high-precision constant temperature cooling device includes a mounting base 04, a housing 01 on the side of the mounting base 04, and a mounting platform 05 on the upper surface of the mounting base 04. A cooling unit 03 is mounted on the mounting base 04 and the mounting platform 05. The cooling unit 03 includes a first plate evaporator 1, which is mounted on the surface of the mounting base 04 located on one side of the mounting platform 05. A first compressor 2 is also mounted on the surface of the first plate evaporator 1. A water pump 4 is located in the middle of the upper surface of the mounting platform 05. A second compressor 5 and a second plate evaporator 6 are mounted on the side of the water pump 4 near the first plate evaporator 1. A high-efficiency tank 3 and a cooling plate 9 are mounted on the side of the water pump 4 near the first compressor 2. A condenser 7 is mounted on a plate on one side of the upper surface of the mounting platform 05. The multiple compressors and plate evaporators allow the device to be flexibly adjusted for high-speed operation and achieve higher temperature control accuracy.
[0024] A fan 02 is installed on the top of the housing 01.
[0025] In addition, the output end of the first compressor 2 has pipelines that connect to the first plate evaporator 1 and the high-efficiency tank 3 respectively. A first proportional valve 10 is provided on the pipeline connecting the output end of the first compressor 2 and the first plate evaporator 1. The first proportional valve 10 controls the refrigerant flow by opening and closing, and has high adjustment accuracy.
[0026] The high-efficiency tank 3 has a pipeline connected to the first plate evaporator 1 at its output end. This pipeline is connected to the output end of the first compressor 2 and the pipeline connecting the first plate evaporator 1. A first capillary tube 11 and a first desiccant tube 8 are provided on this pipeline. The first capillary tube 11 and the first desiccant tube 8 achieve water filtration and flow control.
[0027] Meanwhile, the first plate evaporator 1 is provided with pipes connected to the water pump 4 and the cooling plate 9 respectively, and a branch pipe is provided on the pipe connecting the first plate evaporator 1 and the cooling plate 9 to the second plate evaporator 6. The output end of the first plate evaporator 1 is connected to a pipe connected to the low-pressure end of the first compressor 2.
[0028] Furthermore, the output end of the second compressor 5 is provided with a pipeline connected to the input end of the second plate evaporator 6, and a pipeline connected to the condenser 7 is provided on this pipeline. A second proportional valve 12 is provided on the pipeline connecting the second compressor 5 and the condenser 7. The output end of the second plate evaporator 6 is connected to the pipeline connected to the input end of the condenser 7, and a second desiccant tube 13 and a second capillary tube 14 are provided on this pipeline. The second desiccant tube 13 and the second capillary tube 14 realize the filtration and flow control of moisture.
[0029] In this embodiment, the first compressor 2 outputs high pressure and splits into two paths. One path is directly connected to the first plate evaporator 1, and the other path is transmitted to the high-efficiency tank 3 and then to the first plate evaporator 1 for heat exchange. During this process, the refrigerant passes through the first desiccant tube 8 and the first capillary tube 11 for throttling and cooling. Finally, the two paths merge and enter the first plate evaporator 1 to play a role in temperature control. After the refrigerant passes through the first plate evaporator 1 for heat exchange, it goes to the low-pressure end of the first compressor 2.
[0030] Furthermore, the water pump 4 pumps water from its tank and transmits it to the first plate evaporator for heat exchange. After heat exchange, the cooling water is divided into two paths: one path is transmitted to the second plate evaporator 6 for heat exchange, and the other path is transmitted to the cooling plate 9 for temperature control. After the cooling plate 9 controls the temperature, it pumps the cooling water to the client equipment.
[0031] The cooling water that has finished heat exchanged by the client is returned to the cooling equipment and enters the refrigeration element 9 for temperature control. After the temperature control is completed, it returns to the water tank of the water pump 4 to form a loop.
[0032] After the second compressor 5 pumps out refrigerant at high pressure, it splits into two paths. One path is transmitted to the condenser 7, and the other path merges with the pipeline output after heat exchange with the second-type evaporator 6. The two paths of refrigerant merge and enter the condenser 7 to play a role in temperature control.
[0033] In this utility model, the cooling equipment is configured with a first plate evaporator 1, a second plate evaporator 6, a first compressor 2, and a second compressor 5. The parallel design of the dual compressors and dual plate evaporators enables multi-device coordinated control, effectively avoiding local overheating or overcooling phenomena that may occur in traditional single evaporator systems. This significantly improves the uniformity and stability of the cooling effect. The parallel design of the cooling plates 9 provides auxiliary rapid temperature adjustment capability, meeting the stringent requirements of client equipment for transient temperature changes, and achieving higher temperature accuracy.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
