Integrated heater of core-making fluid

Abstract

The invention discloses an integrated heater of core-making fluid. The integrated heater comprises an integrally poured and molded heating body, wherein the heating body is provided with a runner structure; the runner structure comprises runner units successively arranged along a first set direction and transition runners extended along the first set direction; each runner unit comprises body runners successively arranged along a second set direction and extended along a third set direction and circuitous runners extended along the second set direction; the circuitous runners are used for connecting ports of two adjacent body runners; the transition runners are used for connecting the body runners of the adjacent runner units; the runner structure extends along a substantially-S-shaped direction of the first set direction and the second set direction, so that the heat exchange area between the fluid of the heating body and the heating body is increased; the fluid heating speed is significantly improved; meanwhile, the heating body and the runner structure are integrated to be a whole structure; the sealing performance of the runner is ensured; the integrated heater can heat various fluids; the pollution to the environment caused by leakage is avoided.

Description

technical field [0001] The invention relates to the field of fluid heating, in particular to a fluid heater suitable for fluid heating occasions such as core box air blowing and core box heating of a foundry equipment core making machine. Background technique [0002] In many different applications, it is necessary to rapidly increase the temperature of the fluid to achieve a higher service temperature, for example, to provide ready-to-use high-temperature liquids or gases for homes, offices, campuses, and industrial processes. In the prior art, there are usually two ways of directly heating the fluid by electric heating or indirectly heating the fluid by heating the heat transfer medium. The pipeline heater is such a structure. This type of structure usually adopts a welded or assembled structure. Affected by many factors such as processing and assembly, the design of the flow channel is relatively regular, and it is impossible to achieve high heat exchange efficiency per u...

In the prior art, there are usually two ways of directly heating the fluid by electric heating or indirectly heating the fluid by heating the heat transfer medium. The pipeline heater is such a structure. This type of structure usually adopts a welded and assembled structure. Affected by many factors such as processing and assembly, the design of the flow channel is relatively regular, and it is impossible to achieve high heat exchange efficiency per unit volume, and there is also a relatively high risk of leakage, and the volume is relatively large
