Problems solved by technology

Some water tanks need better heat dissipation performance during use, but most of the existing water tanks are made of stainless steel, the heat dissipation performance of stainless steel is not very good, and if the metal heat dissipation is better copper alloy, the existing copper The performance of the alloy is not high. While ensuring the heat dissipation performance, the mechanical strength of the alloy cannot be guaranteed. Therefore, it is necessary to improve the existing technology to provide a water tank with rapid heat dissipation and high mechanical strength.

Abstract

The invention relates to a water tank. The water tank is made of copper alloy, and the composition of the copper alloy is: Sn1-2%, Ni1-2%, Si0.1-0.2%, Zn0.2-0.5% , Mn0.02~0.04%, Bi0.1~0.2%, Cr0.15~0.3%, Sc0.01~0.04%, Al2O30.5~3%, graphite 2~3%, and the balance is Cu. The present invention adopts a suitable element ratio to give full play to the strengthening effect of each element to ensure the maximum performance of the copper alloy; the optimized preparation method is used to further improve the performance of the copper alloy during the preparation process, thereby improving the heat dissipation and mechanical properties of the final water tank performance.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a water tank. Background technique [0002] The sink is the heart of the kitchen and an indispensable part of the cabinet installation. Among all kinds of supplies in the kitchen, the sink has the highest usage rate. In the pre-meal preparation and post-meal cleaning work, most of the time is directly related to the use of the sink. Sinks in modern kitchens are often produced with stainless steel as raw materials. Stainless steel is light in weight, stable in performance and durable. Through precision machining, it can be made into sinks of different shapes and styles, and can be used with various kitchen countertops. Some water tanks need better heat dissipation performance during use, but most of the existing water tanks are made of stainless steel, the heat dissipation performance of stainless steel is not very good, and if the metal heat dissipation is better copper alloy, the...
