Problems solved by technology

[0003] In the prior art, the liquid replenishment device of the heat exchange system needs to manually open the liquid replenishment cover to add liquid, and after the liquid replenishment port cover of the liquid replenishment device is closed, it is a closed space. Flow, unable to exhaust, so that the pressure in the device increases and bulging occurs
In addition, when the return liquid of the conventional liquid replenishment device falls from the top, it will have an impact on the liquid surface, which will cause the liquid level float to malfunction and even trigger an alarm

Embodiment Construction

[0021] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0022] Such as figure 1 and figure 2 In the shown embodiment, it mainly includes a rehydration tank 1 , and a plurality of rehydration inlets 8 are arranged side by side on the back side of the top of the rehydration tank 1 .

[0023] Such as figure 1 and figure 2 In the shown embodiment, a liquid rehydration outlet is provided on the side wall of the front end of the rehydration tank 1, and one end of the rehydration outlet pipe 9 is connected to the rehydration outlet. The joint 11 is used to connect the heat exchange system.

[0024] In order to control the on-off of the liquid supplement outlet pipe 9, as figure 1 and figure 2 In the shown embodiment, a solenoid valve 10 is arranged on the liquid replacement outlet pipe 9 , and the solenoid valve 10 can control the on-off of the liquid replacement outlet pipe 9 .

Abstract

The invention relates to the technical field of heat exchange systems, in particular to a liquid supplementing device of a heat exchange system. The liquid supplementing device comprises a liquid supplementing tank, and a plurality of liquid supplementing inlets are formed in the rear side of the top end of the liquid supplementing tank side by side and communicated with an inner cavity of the liquid supplementing tank. A liquid supplementing outlet is formed in the side wall of the front end of the liquid supplementing tank and connected with one end of a liquid supplementing outlet pipe, the liquid supplementing outlet pipe is located outside the liquid supplementing tank, and the other end of the liquid supplementing outlet pipe is connected with a pipe joint used for being connected with a heat exchange system. A first water baffle and a second water baffle are arranged in the liquid supplementing tank, so that the situation that liquid level floating balls operate mistakenly due to liquid return impact is avoided; and the height of a first water hole is lower than that of a second water hole, so that the liquid splashing phenomenon caused by falling impact of the return liquid of a liquid storage tank can be further prevented, and false operation alarm of the floating ball liquid level meters is prevented.

Description

technical field [0001] The invention relates to the technical field of heat exchange systems, in particular to a liquid replenishment device for a heat exchange system. Background technique [0002] In the field of heat exchange systems, the temperature of the circulating fluid rises after absorbing heat energy, and the volume of the circulating fluid expands. The liquid circulation system is a closed circuit. If there is no suitable constant pressure replenishment tank, the circulating medium will contain gas, which will affect At the same time, as the volume expands, the pressure in the pipe will also increase. On the contrary, when the temperature is lowered, the volume of the liquid becomes smaller, and a negative pressure is also generated in the pipe, which will also have an adverse effect on the flow rate and pressure. In the prior art, a liquid replenishment device is generally used to accommodate the volume change of the circulating fluid due to thermal expansion a...
