Embodiment Construction
[0008] One end of the heat exchanger 1 is provided with a heated fluid output port 2 and a medium input port 3, and the other end is provided with a medium output port 4 and an unheated fluid input port 5, and a temperature is connected to the port where the medium flows out of the heat exchanger 1. The sensor 6 is connected in series with another temperature sensor 7 and an electric valve 8 at the port where the unheated fluid flows into the heat exchanger 1 . The direction of medium flow is generally opposite to the direction of heated fluid flow. During the heat exchange process, the controller receives the temperature data of the medium collected by a temperature sensor 6 and the temperature data of the unheated fluid collected by another temperature sensor 7, and adjusts the opening degree of the electric valve 8 after calculation, that is, the flow rate, so that a temperature The temperature of the medium at the sensor 6 is equal to or slightly higher than the temperatur...

One temperature sensor is connected to a medium outflowing port of a heat exchanger, and the other temperature sensor and an electrically operated valve are connected in series to a port where unheated fluid flows into the heat exchanger. The temperature sensor, the other temperature sensor and the electrically operated valve are respectively in electrical connection with a controller. The flowing direction of a medium is opposite to the flowing direction of heated fluid or is generally opposite to the flowing direction of heated fluid. In a heat exchange process, the controller receives the temperature data, collected by the temperature sensor, of the medium and the temperature data, collected by the other temperature sensor, of the unheated fluid. After calculation, the opening degree, i.e., an excess flow, of the electrically operated valve is adjusted, thereby enabling the temperature of the medium at the temperature sensor to be equal to or slightly higher than the temperature of the unheated fluid at the other temperature, thereby achieving the purpose of fully exchanging heat.
Description
Technical field [0001] The invention relates to a fluid heat exchanger, especially a fluid sufficient heat exchanger and a control method thereof. technical background [0002] Currently, the best configuration for a fluid heat exchanger is one in which the direction of flow of the exothermic fluid, or medium, is opposite or generally opposite to the direction of flow of the heated fluid. [0003] Specifically, there is a coaxial heat exchange tube of a heat exchanger, the tube through which the medium flows is sleeved in the tube through which the heated fluid flows, and there are two ports at both ends. The interface A at one end communicates with the interface A at the other end, and the interface B at the one end communicates with the interface B at the other end. The interface A at one end is the input end of the medium, and the interface A at the other end is the output end of the medium. The one end interface B is the output end of the heated fluid, and the other en...
