MR037 Educational Bench for Studying Heat Exchangers Heat Transfer Laboratory Equipment Didactic Equipment
1. Introduction to the equipment
1.1 Overview
In nature, energy changes occur every moment, such as heat transfer from one surface to another, but no matter how they are transferred, they will follow the law of conservation of energy. The law of conservation of energy is one of the universal basic laws of nature. Generally speaking, energy will neither be created nor destroyed, it will only be transformed from one form to another, or transferred from one object to another, while the total amount of energy remains unchanged. Therefore, the total amount of heat will not change, it will only be transferred. The transfer of heat cannot be directly observed through phenomena. How heat is transferred on different structural objects is a problem we need to study, and the law of heat transfer is also the focus of our research.
In order to more intuitively obtain the law of temperature change during heat transfer, we designed and produced MR037 teaching table equipment for studying heat exchangers and matching experimental module components. The combination of modules can meet a variety of experimental needs.
1.2 Features
(1) Safer. The product fully considers the user's safety at the beginning of the design, and adopts excellent electrical layout and grounding reliability solutions.
(2) Easier to use. The product adopts a modular design. Both the electrical structure and the mechanical structure use modular design. The structure and principle are clear and understandable, which makes it easier for users to use.
(3) More beautiful. The product adopts an integrated design. The equipment is small and beautiful, and still has very rich functions. Due to the integrated design, the equipment has extremely low environmental requirements.
(4) More durable. The product uses more solid and corrosion-resistant materials, which can greatly extend the service life of the equipment.
