Abstract
Description
Technical Field
[0001] This utility model relates to the field of evaporator technology in Rankine cycle, and specifically to an evaporator for Rankine cycle. Background Technology
[0002] As a classic theory in the field of thermodynamics, the Rankine cycle not only supports the efficient utilization of traditional energy, but also realizes the conversion of thermal energy into mechanical energy through the state changes of the working fluid (such as water vapor or organic working fluid) in four key devices.
[0003] This includes evaporators, which are used to receive high-temperature and high-pressure airflow, enabling efficient cooling as it passes through the evaporator. However, traditional evaporators mostly use passive evaporation, which not only results in low cooling efficiency but also takes a long time.
[0004] Therefore, we propose an evaporator capable of active cooling, which can be effectively applied in the Rankine cycle. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides an evaporator for the Rankine cycle to achieve active cooling and improve cooling efficiency.
[0006] This utility model provides an evaporator for a Rankine cycle, comprising: a plate heat exchanger body; thermally conductive heat sinks; multiple thermally conductive heat sinks are evenly distributed and installed on the outer wall of the plate heat exchanger body, and one end of each heat sink is fixedly connected to the plate heat exchanger body; a cold liquid assembly, comprising a cold liquid tank, a return pipeline, and a liquid pump; the cold liquid tank has a flow chamber and an ice-making chamber; liquid is injected into the flow chamber, and the other end of each thermally conductive heat sink extends into the flow chamber and is submerged below the liquid surface; the return pipeline is installed at both ends of the flow chamber, and the liquid pump is installed in the return pipeline; and an ice-making assembly, connected to the cold liquid assembly and communicating with the ice-making chamber, and used to prepare ice cubes in the cold liquid tank.
[0007] Furthermore, the heat sink is also provided with ventilation holes, which are provided in multiple locations and evenly distributed on the heat sink. In practical applications, the purpose of this design is to further enhance the ventilation effect, thereby enhancing the heat dissipation effect.
[0008] Furthermore, the diameter of the ventilation holes on any of the heat-conducting fins is different. In practical applications, the purpose of this design is to enhance airflow.
[0009] Furthermore, the cold liquid tank is provided with a partition plate, wherein the liquid flow chamber and the ice-making chamber are respectively located on both sides of the partition plate; the liquid flow chamber is located above the ice-making chamber. In practical applications, the purpose of this design is to facilitate the formation of different functional cavities. At the same time, this method allows for easy differentiation and achieves a separation effect.
[0010] Furthermore, the separating plate is provided with at least one ice-making slot, and the ice-making slots are evenly distributed on the separating plate. In practical applications, the purpose of this design is to increase the contact area, thereby enhancing the cooling effect. In actual operation, the ice-making slot is a blind hole, and water accumulates here when it flows through. When the ice-making component in the ice-making cavity is cooled, it can effectively achieve the ice-making effect, thereby achieving efficient cooling. The low temperature is then conducted to the plate heat exchanger body through the heat-conducting fins. In this way, the cooling effect is achieved. Combined with the above-mentioned cold liquid component to enhance liquid circulation, the cooling effect is further enhanced.
[0011] Furthermore, the ice-making assembly includes a compressor, a condenser radiator, an expansion valve, and a condenser evaporator. In practical applications, this design aims to achieve cooling. Because this method is simple, efficient, mature, and readily available, its design principle will not be elaborated further here.
[0012] As can be seen from the above technical solution, the beneficial effects of the evaporator for the Rankine cycle provided by the present invention are as follows:
[0013] (1) In practical applications, the purpose of this design is to achieve efficient cooling and active cooling; heat is conducted through the heat-conducting heat sink, and then through the zero-degree ice-water mixture generated by the cold liquid component and the ice-making component to achieve efficient cooling, thus ensuring the cooling effect.
