AI Technical Summary
The heating element of existing mold temperature controllers comes into direct contact with the liquid medium, leading to the formation of scale and rust, which reduces heating efficiency and service life.
Indirect heating is achieved by using a delivery pipe that wraps tightly around the outer side wall of the heater. 304 stainless steel water pipes and high-temperature die-cast aluminum body materials are used, combined with an over-temperature controller to achieve uniform heating and precise temperature control.
This avoids the formation of scale and rust on the surface of the heating device, improving heating efficiency and extending the service life of the mold temperature controller.

[0016] Fig. 2 It is the sectional view schematic diagram of the internal structure of the utility model.
[0017] Fig. 3 It is the explosion schematic diagram of the utility model. DETAILED DESCRIPTION
[0018] In order to facilitate the person skilled in the art to understand the utility model, the specific embodiment of the utility model is explained below in detail in conjunction with the drawings, and obviously, the specific embodiment described is only the preferred embodiment of the utility model, not all embodiments.
[0019] As Figs. 1-3 Indicated, a kind of heating device provided by the utility model is used to indirectly heat liquid medium;Including main casing 1, the conveying pipe 2 for conveying liquid medium and the heater 3 for providing heating source and indirectly heating the liquid medium conveyed by conveying pipe 2;The main casing 1 has installation cavity inside, the conveying pipe 2 is tightly arranged around on the outer peripheral sidewall of heater 3 and is embedded in installation cavity transversely, the input end and output end of the conveying pipe 2 are connected with water inlet pipe 5 and water outlet pipe 6 respectively arranged on the both ends of main casing 1;Further realize that heater indirectly heats the liquid medium conveyed in conveying pipe evenly and quickly, improve heating efficiency.
[0020] Still include over-temperature controller 4 on main casing 1 and with heater 3 electrically connected;For accurately control the heating temperature of heater 3.
[0021] The heater 3 includes fixed plate 31 and several electric heating rods 32, and the several electric heating rods 32 are arranged on the fixed plate 31 in a ring shape at equal intervals;Improve heating efficiency.
[0022] The main casing 1 in the embodiment is preferably a high-temperature aluminum die-casting body;Fast heat transfer while avoiding excessive local temperature difference.
