Description

Technical Field

[0001] This utility model relates to the technical field of temperature control equipment, specifically a constant temperature circulating water tank for a calorimeter. Background Technology

[0002] Each experiment in the calorimeter main system generates approximately 2 liters of hot water. This hot water needs to be processed by the refrigeration unit to reach room temperature for the next experiment. However, if this hot water is directly placed into the main water tank, the temperature of the water in the main water tank, which has already been processed to room temperature, will rise rapidly, prolonging the water processing time and thus increasing the time interval between experiments. Furthermore, the existing compressor refrigeration method for water tanks also has many problems, such as large size, low efficiency, and high cost. Therefore, we propose a constant temperature circulating water tank for calorimeters to overcome the shortcomings of existing technologies. Utility Model Content

[0018] Please see Figure 1-3This utility model provides a technical solution: a constant temperature circulating water tank for a calorimeter, including a main water tank 1 and an auxiliary water tank 2. The auxiliary water tank 2 is installed on the side wall of the main water tank 1. The interior of the main water tank 1 is provided with several perforated partitions 3 from top to bottom. The top of the main water tank 1 and the top of the side wall are respectively provided with a water inlet 4 and an overflow outlet 5. The bottom and middle of the side wall of the main water tank 1 are respectively provided with a circulating water outlet 6 and a circulating water inlet 7. The bottom wall of the main water tank 1 is provided with a drain outlet 8. A cooling mechanism 9 is provided on one side of the main water tank 1. The circulating water outlet 6 and the circulating water inlet 7 are connected to the cooling mechanism 9 to exchange heat and reduce the water temperature. A heating element 10, which is an electric heating rod, is provided on the lower side of the partition in the middle of the main water tank 1.

[0019] The interior of the auxiliary water tank 2 is provided with several perforated partitions 11 from top to bottom. The top wall of the auxiliary water tank 2 is provided with an auxiliary water outlet 12. The bottom of the side wall of the auxiliary water tank 2 is provided with an auxiliary water inlet pipe 13, which passes through the main water tank 1 to its outside.

[0020] After the calorimeter test, the hot water enters the auxiliary water tank 2 through the auxiliary inlet pipe 13 for temporary storage. It is partially cooled by the low-temperature water in the main water tank 1. The hot water for the next test continues to enter through the auxiliary inlet pipe 13, while the water from the previous test is squeezed out from the auxiliary outlet 12 into the main water tank 1. (Feature: to avoid the hot water from entering the main water tank 1 directly after the test, which would cause a sudden increase in the water temperature in the main water tank 1). The function of the perforated baffle 11 is to form a unidirectional water flow path, ensuring that all the hot water from this test remains in the auxiliary water tank 2 first.

[0021] The cooling mechanism 9 includes a circulating water box 91, a cooling water inlet pipe 92, a cooling water outlet pipe 93, a semiconductor cooling component 94, heat dissipation fins 95, and a cooling fan 96. The circulating water box 91 is installed on the side wall of the main water tank 1. The cooling water inlet pipe 92 and the cooling water outlet pipe 93 are respectively fixedly connected to the top of the circulating water box 91. The cooling water inlet pipe 92 is connected to the circulating water outlet 6, and the cooling water outlet pipe 93 is connected to the circulating water inlet 7. The heat absorption side of the semiconductor cooling component 94 is installed on the side of the circulating water box 91 away from the main water tank 1. The heat dissipation fins 95 are installed on the heat dissipation side of the semiconductor cooling component 94. A cooling fan 96 is installed on the heat dissipation fins 95. In order to enhance the heat transfer efficiency, thermal grease is used to enhance the contact between the heat dissipation fins 95 and the heat source and the cooling fan 96, which is a known technology. The semiconductor cooling component 94 absorbs heat in the circulating water box 91 and transfers it to the heat dissipation fins 95, which is then dissipated by the cooling fan 96.

[0022] A water pump 15 is installed between the circulating water outlet 6 and the cooling water inlet pipe 92 to provide power for water circulation.

[0023] Water flow path: After the main system experiment is completed, 2L of hot water is generated and discharged through the main system water pump to the auxiliary water inlet pipe 13 and enters the bottom of the auxiliary water tank 2. Due to the design of the perforated partition 11 of the auxiliary water tank 2, the water will form a single flow direction, and the water in the auxiliary water tank 2 will be squeezed out from the auxiliary water outlet 12. The water flows out from the auxiliary water outlet 12 to the upper side of the main water tank 1. The water in the main water tank 1 flows through the multi-layer perforated partition 3 to the circulation outlet 6, and enters the cooling water inlet pipe 92 through the water pump 15. It circulates in the circulation water box 91 and is discharged through the cooling water outlet pipe 93. Then it passes through the circulation inlet. During the circulation process, it is cooled by the semiconductor cooling component 94 and enters the main water tank 1 through the circulation inlet 7 to form a circulation. The temperature probe 14 monitors the water temperature in the main water tank 1. When the temperature is higher than the set temperature, the cooling circulation is performed. When the temperature is lower than the set temperature, the heating element 10 works to heat the water in the main water tank 1. The experimental water is taken from the drain outlet 8.

[0024] In this cycle, the temperature probe detects the water temperature in the main water tank 1, and the temperature controller controls the refrigeration. As a well-known technology, such as the refrigeration system of a refrigerator, the temperature is detected by a temperature sensor and fed back to the controller to control the compressor. For those skilled in the art, this is a choice they can make freely, and will not be elaborated upon further.

[0025] A temperature probe 14 is installed on the inner wall of the main water tank 1 to detect the water temperature inside the main water tank 1.

[0026] There are at least two perforated partitions 3, which are parallel to each other, and the holes on adjacent perforated partitions 3 are staggered.

[0027] There are at least two perforated partitions 11 that are parallel to each other, and the holes on adjacent perforated partitions 3 are staggered so that the water in the auxiliary water tank 2 flows from bottom to top in a single stream. The water entering through the auxiliary water inlet pipe 13 can push the original water in the auxiliary water tank 2 out through the auxiliary water outlet 12.

[0028] Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
