Problems solved by technology

However, the existing premixing process is realized by drastic changes in the flow area and flow direction. This process is accompanied by serious flow loss, resulting in an increase in the pressure loss of the water mixer, which also reduces its operating economy.

Abstract

The invention discloses a blade type water mixer. The blade type water mixer sequentially comprises a straight cylinder section, a gradually-widened section, a pre-rotating section and a water outletsection in the water flow direction. The blade type water mixer comprises a shell arranged on the outer side and an inner container arranged in the shell, wherein the two ends of the inner container communicate with each other. The inner container is located on the straight cylinder section, the gradually-widened section and the pre-rotating section. The gradually-widened section is provided witha center partition plate used for heat conduction. Flow guide blades are arranged on the outer wall of the inner container on the pre-rotating section. According to the blade type water mixer, based on numerical analysis of the flowing and heat exchange characteristics in a prototype water mixer and a water mixer of a jet flow mixing structure in the prior art, it is guaranteed that the key of efficient low-pressure-loss mixing constant-temperature output lies in sufficient contact of cold water and hot water and efficient flow division of the cold water and the hot water. By designing a reasonable flow channel structure, a large-flow main flow is dispersed into fine branches, and the cold water branches and the hot water branches are mixed to achieve efficient heat exchange.

Description

Technical field[0001]The present invention relates to a blade-type water mixer, and more specifically, to a listening blade-type water mixer with high heat exchange efficiency.Background technique[0002]The current existing water mixer structure includes the first type of direct mixing of hot and cold water into a larger storage tank. This method has a simple structure, but the mixing effect is directly related to the size of the storage tank, which results in this type of mixer. In order to ensure the temperature of the water supply, a large storage tank is usually required. In addition, due to the different needs of the water end in the application process, the heat loss of the large amount of hot water in the storage tank will cause energy waste and reduce the economic efficiency of its system operation. The second is to change the injection form of cold and hot water in the mixer to make it have a certain mixing effect before entering the storage tank. This structure increases th...
