Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration unit supporting equipment, and particularly relates to a liquid receiver with a thermosiphon function. Background Art

[0002] A liquid receiver is one of the supporting components of a refrigeration system. It is installed between a condenser and an evaporator and is used to temporarily store the liquid condensed by the condenser, playing a buffering role, so that the refrigeration system can adapt to the change of refrigerant charge under high and low loads.

[0003] In the existing refrigeration system, an independent siphon tank and a liquid receiver are generally adopted. The liquid obtained by condensing through the condenser first enters the siphon tank, and then enters the liquid receiver through the connecting pipe between the siphon tank and the liquid receiver. Multiple connecting pipes and supporting valves need to be configured between the siphon tank and the liquid receiver, and the structure is relatively complex and the cost is relatively high. Moreover, it also leads to an increase in floor area, as well as an increase in cost and the time of on-site construction. Therefore, it has limitations. Summary of the Utility Model

And a thermosiphon oil cooling supply pipe connected to the thermosiphon liquid storage space is provided.

[0006] At most five partition plates are provided in the liquid storage cavity for partitioning a thermosiphon liquid storage space with an upward opening in the liquid storage cavity.

[0007] The inlet pipe is located at the top of the liquid storage tank and is used to communicate with the condenser.

[0008] The outlet pipe is located at one side end of the liquid storage tank and is arranged close to the bottom end of the liquid storage tank, and is used to communicate with external equipment.

[0009] The balance pipe is located at the top of the liquid storage tank and is used to balance the air pressure between the thermosiphon liquid storage space and the liquid storage cavity.

[0010] The thermosiphon oil cooling return air pipe is located at the other side end of the liquid storage tank and is above the thermosiphon liquid storage space, and is used to communicate with the return air port of the oil cooler.

[0016] Functions and effects of the utility model

[0017] According to the liquid storage device with a thermosiphon function involved in the present utility model, it aims to make the condensed liquid first enter the thermosiphon liquid storage space after passing through the liquid inlet pipe, so that the liquid is preferentially used to absorb heat and evaporate in the oil cooler, making the heat exchange efficiency relatively high. When the liquid in the thermosiphon liquid storage space overflows into the liquid storage cavity, the liquid is then supplied for the refrigeration of the system. Moreover, one device of the present utility model realizes the functions achieved by two devices, namely the thermosiphon barrel and the liquid storage device. Therefore, it reduces the floor area, construction cost, on-site construction difficulty and time of the devices.
