Accurate temperature control is the most important and basic function of biopharmaceutical equipment.

[0003] In order to ensure the accuracy and convenience of temperature control, it is necessary to equip the biopharmaceutical equipment with a corresponding temperature control module. If necessary, the temperature control module needs to be compact, easy to disassemble and easy to maintain. There are two most commonly used temperature control methods in the prior art, one is an industrial steam generator and the other is an industrial chiller. Both methods are large-scale equipment, occupy a large area and are costly. It is impossible to equip each device with these two devices, and the installation is also inconvenient. Utility Model Content

[0007] The water supply pipe and the return pipe are connected to the water jacket in the biopharmaceutical equipment, the cooling water inlet pipe and the cooling water outlet pipe are connected to the external water cooling circulation system, the water inlet pipe is connected to the water at room temperature, and the drain pipe is emptied; in the initial stage, the water at room temperature is supplied to the circulating temperature control loop and the water jacket of the equipment through the water inlet pipe, and then the heater heats the water in the circulating temperature control loop to a predetermined temperature, and the temperature is monitored by the temperature sensor. When cooling is required, the heat exchanger cools the circulating water in the circulating temperature control loop at the same time, thereby meeting the temperature control requirements of the biopharmaceutical equipment.

[0008] Preferably, the first valve body is configured as a liquid inlet check valve, the second valve body is configured as a manual valve, and a pressure reducing valve is provided on the water inlet pipe at the inlet end of the first valve body. The liquid inlet check valve can ensure stable water inflow into the water inlet pipe, and the pressure reducing valve can play a role in pressure reduction, so that the water pressure entering the circulating temperature control loop meets the demand.

[0010] Preferably, a safety valve is provided on the guide pipe, and a pressure gauge is provided on the guide pipe. When the pressure in the circulating temperature control loop is greater than a preset value, the safety valve opens to release the pressure, thereby ensuring the overall stability and safety of use.

In the initial state, when the medium (water) is introduced into the circulating temperature control loop through the water inlet pipe, the exhaust valve is opened to facilitate the exhaust of the gas in the circulating temperature control loop and prevent the residual air in the circulating temperature control loop from affecting the temperature and the temperature change rate.
