Abstract
Description
Technical Field
[0001] This utility model relates to the field of temperature control, and in particular to a multi-channel temperature controller. Background Technology
[0002] With increasingly stringent national requirements for environmental remediation, temperature controllers are finding wider application in engineering. Existing temperature controllers, when operating under multi-channel control, generate significant heat under high power and current conditions, especially when overcurrent or overload caused by external factors. If this heat cannot be dissipated promptly or if power-off protection is not implemented in time, components may burn out. Therefore, it is necessary to incorporate heat dissipation devices and overcurrent protection into the circuit to ensure timely heat dissipation and prompt power-off protection in case of overload, thus protecting components and the entire circuit, improving product lifespan and safety.
[0003] In addition, although electrical equipment currently used in the market can be equipped with external fuses, external fuses will increase the number of wiring connections. For high-current electrical equipment, each additional wiring connection will increase the potential for failure due to poor wiring contact. Furthermore, when the number of electrical loads used on large machines is huge, the wiring will become more complex when external fuses are installed, and the production requirements for workers will also be higher, thus increasing production costs. Utility Model Content
[0004] The purpose of this invention is to provide a multi-channel temperature controller that enables independent control of multiple channels and improves the protection function of each channel, thus solving the problem that a problem in one channel of multi-channel control can affect the normal operation of the entire controller.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a multi-channel temperature controller, including a left base and a right base, with a detachable main housing between the left and right bases, a circuit board inside the main housing, and three-phase input terminals and multiple output terminals connected to the circuit board on the upper surface of the main housing; signal terminals connected to the circuit board are provided on the left and right bases; a set of external mounting holes are provided on the left and right bases respectively; a set of fuse slots is provided on the upper surface of the main housing, and each fuse slot is provided with an openable and closable waterproof sealing cover; a set of fuse holders is provided in each fuse slot, and a fuse is provided on each fuse holder; each output terminal in the multiple output terminals corresponds to a fuse holder.
[0006] To improve heat dissipation performance, a heat sink is installed inside the main housing, and the circuit board is mounted on the heat sink. A set of cooling fans is also installed inside the main housing, and an air outlet adapted to the cooling fans is provided on one side of the outer wall of the main housing.
[0007] To achieve multi-output control and independent protection for each output, the multi-output terminals are divided into three groups corresponding to the three-phase input terminals, with each group including five output terminals. Each group of multi-output terminals corresponds to a fuse slot, and each fuse slot is equipped with five fuse holders. Each output terminal is connected to a fuse.
[0008] To facilitate fuse replacement, a set of spare holders is provided on one side of the outer wall of the main housing, and each spare holder is equipped with a spare fuse.
[0009] To achieve air isolation at the bottom of the circuit board and further improve heat dissipation, a positioning seat is installed inside the left and right bases, and the bottom ends of the circuit board are mounted on the positioning seats.
[0010] The beneficial effects of this utility model are as follows: The multi-output terminals enable multiple outputs; the fuse slots, combined with waterproof sealing covers, improve the sealing and waterproof performance of the fuse slots; each output terminal corresponds to a separate fuse, enabling independent protection for each output and preventing a problem in one output from affecting the normal operation of the others; the fifteen output terminals are divided into three groups, with five output terminals in each group, enabling multi-output control and independent control for each group; each group corresponds to a fuse slot, further enhancing the independence of each group; each group has five fuse holders, improving the independence of each fuse, thus achieving independent output for all fifteen outputs and independent protection, preventing a problem in one output from affecting the normal operation of the others, and improving the controller's continuous operation capability.
