Description

Technical Field

[0001] This utility model belongs to the field of electrical control box technology, specifically relating to an electrical control box for a heat exchanger unit. Background Technology

[0002] A heat exchange unit consists of a heat exchanger, a temperature control valve assembly, a steam trap assembly (when the heat medium is steam), a circulating pump, an electrical control cabinet, a base, piping, valves, and instruments. It can also be equipped with an expansion tank, water treatment equipment, variable frequency pump control, temperature control valves, and remote communication control, thus forming a complete heat exchange station. The heat exchange unit features a standardized and modular design, comprehensive configuration, convenient installation, and high energy efficiency.

[0003] Currently, all existing heat exchange units are equipped with electrical control boxes for controlling the heat exchange units. However, due to the small internal space of the existing electrical control boxes, it is very inconvenient to install and disassemble electrical components inside, which affects the efficiency of installation and maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide an electrical control box for a heat exchanger unit to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrical control box for a heat exchanger unit, comprising a box body, a mounting plate, and a fixing seat. The mounting plate is installed inside the box body via the fixing seat. There are two fixing seats, which are respectively fixedly installed on the two inner side walls of the box body. Grooves adapted to the fixing seats are provided on both sides of the mounting plate. Connecting holes are provided at both the upper and lower ends of the grooves. Connecting rods adapted to the connecting holes are slidably installed on both the upper and lower sides of the fixing seat. A horizontally arranged screw is rotatably installed inside the fixing seat. One end of the screw extends through to the outside of the fixing seat and is fixedly connected to a knob. A slider is threadedly connected to the screw. A movable rod is hinged between the slider and the connecting rod.

[0006] In a preferred embodiment, the front of the enclosure is hinged with a door.

[0007] In a preferred embodiment, heat dissipation holes are provided on both sides of the housing, and a filter screen is fixedly connected to one end of the heat dissipation hole near the outside of the housing.

[0008] In a preferred embodiment, two T-shaped slide rails are fixedly connected to the inner top wall and inner bottom wall of the housing, and T-shaped grooves that are adapted to the T-shaped slide rails are provided at both the upper and lower ends of the mounting plate.

[0009] In a preferred embodiment, a limiting plate is fixedly connected to one side of the fixing base.

[0010] In a preferred embodiment, a guide rod is fixedly connected inside the fixed base, and the slider is slidably sleeved on the guide rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The electrical control box of this heat exchanger unit, through the setting of the fixed base, allows the mounting plate to slide on the fixed base with the grooves on both sides of the mounting plate during installation. When the connecting hole is aligned with the connecting rod, the knob can be rotated to rotate the screw, causing the screw to drive the slider to slide. The slider, through the movable rod, drives the connecting rod to insert into the connecting hole, thus fixing the mounting plate. When electrical components need to be installed or removed, the knob can be rotated to move the connecting rod out of the connecting hole, allowing the mounting plate to be removed from the box. This facilitates the installation and removal of electrical components and improves installation and maintenance efficiency.

[0013] The electrical control box of the heat exchanger unit, through the setting of T-shaped slide rails and T-shaped grooves, allows the T-shaped grooves at both ends of the mounting plate to fit onto the T-shaped slide rails during installation, so that the mounting plate can slide along the T-shaped slide rails, which facilitates the guidance and positioning of the mounting plate.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0020] Please see Figure 1-3This utility model provides an electrical control box for a heat exchanger unit, including a box body 1, a mounting plate 2 and a fixing base 3. A box door 11 is hinged to the front of the box body 1. Heat dissipation holes 12 are provided on both sides of the box body 1. A filter screen 13 is fixedly connected to one end of the heat dissipation hole 12 near the outside of the box body 1. Through the arrangement of the heat dissipation hole 12 and the filter screen 13, convective air can be generated inside the box body 1 to help dissipate heat inside the box body 1, while reducing the entry of external dust into the box body 1.

[0021] Reference Figures 1-3 The mounting plate 2 is installed inside the housing 1 via fixing seats 3. There are two fixing seats 3, which are respectively fixedly installed on the two inner side walls of the housing 1. Both sides of the mounting plate 2 are provided with grooves 21 that are adapted to the fixing seats 3. Both ends of the grooves 21 are provided with connecting holes 22. Both sides of the fixing seats 3 are slidably installed with connecting rods 31 that are adapted to the connecting holes 22. A horizontally arranged screw 32 is rotatably installed inside the fixing seat 3. One end of the screw 32 passes through the outside of the fixing seat 3 and is fixedly connected to a knob 33. A slider 34 is threadedly connected to the screw 32. A movable rod 35 is hinged between the slider 34 and the connecting rod 31. A guide rod 37 is fixedly connected inside the fixing seat 3. The slider 34 is slidably sleeved on the guide rod 37. With the setting of the fixing seat 3, when installing the mounting plate 2, the grooves 21 on both sides of the mounting plate 2 can be slid onto the fixing seat 3. When the connecting hole 22 is aligned with the connecting rod 31, the knob 33 can be rotated to rotate the screw 32, so that the screw 32 drives the slider 34 to slide. The slider 34 drives the connecting rod 31 to be inserted into the connecting hole 22 through the movable rod 35, thus fixing the mounting plate 2. When electrical components need to be installed and removed, the knob 33 can be rotated to move the connecting rod 31 out of the connecting hole 22, so that the mounting plate 2 can be taken out from the box 1. This facilitates the installation and removal of electrical components and improves the efficiency of installation and maintenance.

[0022] Furthermore, two T-shaped slide rails 14 are fixedly connected to the inner top and bottom walls of the housing 1. T-shaped grooves 23 that are adapted to the T-shaped slide rails 14 are provided at both the upper and lower ends of the mounting plate 2. With the T-shaped slide rails 14 and T-shaped grooves 23, when installing the mounting plate 2, the T-shaped grooves 23 at both ends of the mounting plate 2 can be fitted onto the T-shaped slide rails 14, so that the mounting plate 2 can slide along the T-shaped slide rails 14, which facilitates the guidance and positioning of the mounting plate 2.

[0023] Furthermore, a limiting plate 36 is fixedly connected to one side of the fixed base 3. With the setting of the limiting plate 36, during the process of the mounting plate 2 sliding along the T-shaped slide rail 14, the mounting plate 2 will eventually abut against the limiting plate 36. At this time, the connecting hole 22 is just aligned with the connecting rod 31, thereby limiting the mounting plate 2.

[0024] The working principle and usage process of this utility model are as follows: First, when installing the mounting plate 2, the T-shaped grooves 23 at both ends of the mounting plate 2 can be fitted onto the T-shaped slide rail 14, allowing the mounting plate 2 to slide along the T-shaped slide rail 14 for easy guidance and positioning. The grooves 21 on both sides of the mounting plate 2 can be fitted onto the fixing seat 3 for sliding. During the installation process of the mounting plate 2 sliding along the T-shaped slide rail 14, the mounting plate 2 will eventually abut against the limiting plate 36. At this time, the connecting hole 22 is aligned with the connecting rod 31, limiting the mounting plate 2. Then, the knob 33 can be rotated to rotate the screw 32, causing the screw 32 to drive the slider 34 to slide. The slider 34 drives the connecting rod 31 to insert into the connecting hole 22 through the movable rod 35, fixing the mounting plate 2. When electrical components need to be installed and disassembled, the knob 33 can be rotated to remove the connecting rod 31 from the connecting hole 22, allowing the mounting plate 2 to be taken out from the housing 1, thus facilitating the installation and disassembly of electrical components and improving installation and maintenance efficiency.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
