Easy-to-replace assembly heater block

The present invention relates to a prefabricated heater block that can be easily replaced, and more particularly, to easily assemble and install a plurality of heat transfer media by arranging and fixing a heat transfer medium in a receiving groove formed in a main body and then electrically connecting them through a power connection means. It is very convenient to manufacture the heater block, which is a finished product, and can induce mass production of the device. In addition, when the heating medium fails, only the electrical connection of the power connection means connected to the heating medium is disconnected and then separated and recovered to replace and The present invention relates to a prefabricated heater block that can be easily replaced and can be repaired to induce easy operation and management of the device.

In general, as a device for supplying and heating a heat source, an electric heater device formed with a heat transfer medium such as a heater rod that emits heat when power is supplied is widely used. When a large number of heat sources are required, a plurality of heater rods or electric heaters are used Installed and used multiple times.

However, the conventional electric heater device requires a lot of time and parts to connect a plurality of heat transfer media without a separate assembly means, making it complicated and inconvenient to manufacture, and difficult to manufacture as a standardized device, so the versatility of the device is low. There was a problem.

Furthermore, in the case of the complicated manufacturing as described above, there is a problem in that it is difficult to easily replace and repair the heat transfer medium because it is difficult to simply recover only the failed heat transfer medium when a failure occurs in any one part, for example, the heat transfer medium.

In order to solve the above problems, the applicant of the present invention proposed the development of "prefabricated heater block (registration number: 10-2153139)".

However, the "prefabricated heater block" does not provide a simple structure in which the heater rods are electrically connected, so that when replacing the heater rod of the heater block, too much time and manpower are required to disconnect or connect the electrical connection, so that the device can be operated conveniently. There was a problem in use that management was somewhat difficult.

In addition, the "prefabricated heater block" has a somewhat complicated structure of a heater rod and a part electrically connected to an external power source, which makes it difficult and inconvenient to manufacture the device, and thus the productivity of the device is somewhat low.
