AI Technical Summary

Technical Problem

The existing calorimeter's water tank is inefficient when processing hot water, resulting in longer experimental time intervals. Furthermore, the existing refrigeration methods are bulky, inefficient, and costly.

Method used

A constant temperature circulating water tank for a calorimeter was designed, comprising a main water tank and an auxiliary water tank. The water temperature is regulated by a refrigeration mechanism and a heating element. Hot water is temporarily stored in the auxiliary water tank embedded in the main water tank, and the water is cooled by heat exchange through a semiconductor refrigeration component and a cooling fan, thus isolating the hot water from the room temperature water.

Benefits of technology

It improved water treatment efficiency, shortened the experimental interval, and reduced equipment size and cost.

Abstract

The utility model belongs to the technical field of temperature control equipment, and discloses a constant-temperature circulating water tank for a calorimeter. The constant-temperature circulating water tank for the calorimeter comprises a main water tank and an auxiliary water tank, the auxiliary water tank is installed on the side wall of the main water tank, a plurality of first partition plates with holes are arranged in the main water tank from top to bottom, and a water injection opening and an overflow opening are formed in the top of the main water tank and the top end of the side wall of the main water tank respectively. A circulating water outlet and a circulating water inlet are respectively formed in the bottom and the middle of the side wall of the main water tank. According to the constant-temperature circulating water tank for the calorimeter, the auxiliary water tank is embedded in the main water tank, serves as a temporary storage space to store hot water discharged by the calorimeter and is only in small-range contact with normal-temperature water in the main water tank, the water temperature of the water in the main water tank is regulated and controlled by the refrigerating mechanism and the heating element, and cooling of the hot water and storage of the normal-temperature water are isolated; the water treatment efficiency is improved, the time interval between experiments is reduced, and the problems in the background technology are solved.
