Problems solved by technology
[0003] Generally, evaporators are used in power systems. When high-temperature fluids such as high-temperature hydraulic oil are used in power systems to reach the evaporator, the refrigerant in the evaporator absorbs the calorific value of high-temperature fluids such as high-temperature hydraulic oil. The agent will also evaporate, so as to cool the high-temperature fluid such as high-temperature hydraulic oil passing through the evaporator, but the current evaporator has the following defects: When the calorific value of the high-temperature fluid absorbed by the shell conduction, such as high-temperature hydraulic oil, exceeds the calorific value required for the liquid refrigerant to evaporate completely into the evaporative refrigerant, that is, when the liquid refrigerant in the evaporator is not completely When the refrigerant evaporates into an evaporative state, there will be a phenomenon that the liquid refrigerant gushes out through the refrigerant discharge hole

Embodiment Construction
[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0033] Such as figure 1 As shown, the evaporator used in the power system includes a hollow cuboid shell, and the shell is provided with a through groove one for sending high-temperature fluid and a through groove two for sending high-temperature fluid; the power system It can be a screw expansion power system heated by solar energy with a low boiling point working medium, a power system for double-tank molten salt storage, a wind energy power system, and a backpack-type modular hydraulic power system used in emergency situations. The high-temperature fluid can be a high-temperature hydraulic pressure that needs to be cooled. Oil. A plurality of cooling devices are arranged on the lower wall of the housing by means of bolts or riveting, and the cooling devices include chambers arranged horizontally to accommodate liquid flow fluids, and chambers arrang...

An evaporator for a power system comprises a hollow shell, and a first through groove used for feeding high-temperature fluid and a second through groove used for discharging the high-temperature fluid are formed in the shell; a plurality of cooling devices are arranged in the shell; and each cooling device comprises a first cavity which is transversely arranged and used for containing liquid-flow-shaped fluid, a second annular-column-shaped cavity which is obliquely arranged and used for containing evaporated-state fluid, and a plurality of third annular-column-shaped cavities which are arranged between the first cavity which is used for containing the liquid-flow-shaped fluid and the second annular-column-shaped cavity which is used for containing the evaporated-state fluid and used for cooling. The third annular-column-shaped cavities for cooling are communicated with the the first cavity which is used for containing the liquid-flow-shaped fluid and the second annular-column-shaped cavity which is used for containing the evaporated-state fluid; and the defect that in the prior art, when liquid-flow-shaped refrigerants in an evaporator for a power system are not completely evaporated into evaporated refrigerants, the liquid-flow-shaped refrigerants can flow out of refrigerant drain holes is effectively avoided.
Description
technical field [0001] The invention relates to the technical field of power system equipment, and also to the technical field of evaporators, in particular to an evaporator used in a power system. Background technique [0002] In many power systems, evaporators are used for refrigeration, which is beneficial to avoid overheating during the operation of the power system, which will cause the power system to fail or fail. Mass screw expansion power system, power system of double-tank molten salt storage, wind energy power system and knapsack modular hydraulic power system used in emergency situations are widely used in such power systems. [0003] Generally, evaporators are used in power systems. When high-temperature fluids such as high-temperature hydraulic oil are used in power systems to reach the evaporator, the refrigerant in the evaporator absorbs the calorific value of high-temperature fluids such as high-temperature hydraulic oil. The agent will also evaporate, so a...
