A spray cooling heat exchanger

Abstract

The invention provides a spray cooling heat exchanger which comprises a heat exchanger core body, spray assemblies and steam outlets. The upper end face and the lower end face of the heat exchanger core body are fixedly connected with the spray assemblies correspondingly, and the left end face and the right end face of the heat exchanger core body are fixedly connected with the steam outlets correspondingly. Each spray assembly comprises a spray cavity shell, a partition plate and spray heads, wherein the spray cavity shell is fixedly connected with the upper end face and the lower end face ofthe heat exchanger core body, the partition plate is arranged in the spray cavity shell, the partition plate is provided with the multiple spray heads, the spray cavity shell is divided into a staticpressure box and a cooling box by the partition plate, the static pressure box is connected with a water inlet pipe, the cooling box is arranged close to the heat exchanger core body, and air outletscommunicating with the steam outlets are reserved on the left end face and the right end face of the cooling box. According to the spray cooling heat exchanger, a spray cooling technology is adopted,so that the heat transfer performance of the heat exchanger is enhanced; and the heat exchanger core body adopts an integral cold plate, the structural performance is improved, and the capability ofovercoming thermal stress is greatly improved.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a spray cooling heat exchanger. Background technique [0002] With the rapid development of modern economy and science and technology, the requirements for various structures and types of heat exchangers are constantly increasing, and heat exchangers with new structures and new materials are also the current research focus of heat exchangers. At present, due to the limitation of material performance and processing technology, the form of liquid-liquid heat exchangers suitable for heat dissipation in high-temperature occasions is relatively simple, such as plate heat exchangers, shell-and-tube heat exchangers, and casing heat exchangers. However, this type of heat exchanger has disadvantages such as large structural size, high liquid resistance, and low heat exchange efficiency. Therefore, the development of a high-temperature resistant heat exchanger with high heat trans...
