The present invention relates to an online temperature monitoring system and method for a direct air-cooled condenser. A temperature sensor moving system is arranged on the surface of the heat exchange tube bundle of the direct air-cooled condenser, and a temperature sensor is installed on said temperature sensor moving system and moves on a plane parallel to the surface of the heat exchange tube bundle. The data collected by the temperature sensor is uploaded to a connected data processing system. Said system can collect, analyze, store and query data and give an alarm based on the predefined settings. Compared with the distribution of a plurality of monitoring cables in the prior art, the present invention realizes the scanning of a plurality of monitoring points, simplifies the cable distribution, avoids any blind monitoring area, and has flexibility.

The invention relates to a device for the thermal management of a battery of electric accumulator cells assembled within a rigid casing, said device comprising thermal storage means incorporated into said battery comprising a chamber containing a phase-change material and having a volume for exchange of heat with said accumulator cells which is delimited by at least part of said casing, the melting of the phase-change material being able to store heat, and the solidification of the phase-change material being able to release the heat previously stored. According to the invention, said chamber is equipped at its distal end with an expansion vessel able to absorb the expansions of said phase-change material as it changes phase.

Preventing freezing in a heat exchanger can include passing first and second cooling fluids through the heat exchanger, monitoring a temperature and/or pressure of the second cooling fluid entering the heat exchanger, heating the second cooling fluid entering the heat exchanger by opening a valve when the monitored temperature and/or monitored pressure is below a trigger temperature and/or trigger pressure, and closing the valve when a condition is met. The first cooling fluid can have a first freezing temperature and the second cooling fluid can have a second, lower freezing temperature. Opening the valve can cause the second cooling fluid, in gaseous phase, to mix with the second cooling fluid, in liquid phase, upstream of the heat exchanger.

There are herein described energy storage systems. More particularly there are provided thermal energy storage systems comprising battery assemblies containing phase change materials and a monitoring system therefor. In addition there are provided thermal stores comprising battery assemblies having integral control means for management of the thermal energy provided by the battery assembly.

A heat exchanger includes a housing configured to contain a working fluid. The heat exchanger also includes a plurality of chambers disposed within the housing and arranged so as to be surrounded by the working fluid when the working fluid is within the housing, each chamber configured to contain a phase change material (PCM) that expands upon freezing. The walls of each chamber are formed of a high thermal conductivity material that allows transfer of thermal energy between the working fluid and the PCM in each chamber. The walls of each chamber include expandable bellows configured to deform to increase an internal volume of the chamber as the PCM expands upon freezing.

A water purifier according to an embodiment comprises: a cooling water tank storing cooling water; a partition member mounted inside the cooling water tank and partitioning an inner space of the cooling water tank into an upper space and a lower space; a cold water pipe which is accommodated in the lower space and through which edible water flows; an evaporator which is accommodated in the upper space and through which a refrigerant flows; and an agitator penetrating the partition member and disposed in the lower space so as to stir the cooling water. The partition member comprises: a bottom portion on which the evaporator is mounted, the bottom portion having a plurality of cooling water through-holes formed therein; and an outer wall portion extending upward along an edge of the bottom portion to form an evaporator accommodating portion. The outer wall portion is spaced apart from an inner wall of the cooling water tank so as to prevent ice formed in the evaporator accommodating portion from being in contact with the inner wall of the cooling water tank.

Liquid cooling station comprises at least one pump and at least one motor connected to the pump for operating the pump to circulate cooling liquid between the cooling station and an object to be cooled, a first cooling liquid outlet port for supplying the cooling liquid towards the object to be cooled and a first cooling liquid inlet port for receiving the cooling liquid from the object to be cooled. The liquid cooling station further comprises at least one connection block, which comprises at least one first cavity for receiving an operating part of the pump, at least one second cavity for an additional operational part, the first cooling liquid inlet and outlet ports and an internal channel system connecting the first cavity to the first cooling liquid inlet and outlet ports.

A cooling module used in conjunction with a heating element includes a vapor chamber and a plurality of cooling fins. The vapor chamber is in contact with one side of the heating element. The vapor chamber is disposed with a direct conduction area and a vacuum block disposed on two sides of the direct conduction area respectively. Each vacuum block forms a chamber. The cooling fins protrude from and are vertically disposed on the direct conduction area and each vacuum block, respectively. Thereby, the effects of fast vertical heat transfer to the fin and fast horizontal heat transfer to the distal cooling fins are achieved.

The present invention provides an energy storage apparatus. The energy storage apparatus comprises a storage tank (100, 220) for receiving thermal energy storage fluid (103, 203) therein, a first energy transfer component (107, 205) and a second energy transfer component (106, 206).

The first portion is in fluid communication with the second portion at the respective first ends and at the respective second ends. The first energy transfer component is configured to transfer thermal energy into thermal energy storage fluid in the first portion of the storage tank. The second energy transfer component is configured to transfer thermal energy from thermal energy storage fluid in the second portion of the storage tank. The energy storage apparatus is configured such that operation of at least one of the first energy transfer component and the second energy transfer component causes convective fluid flow of the thermal energy storage fluid from the first energy transfer component towards the second energy transfer component and from the second energy transfer component towards the first energy transfer component.
