[0002] At present, the reach forklifts produced by our company are semi-enclosed, which solves the heat dissipation problem in the cab. However, due to the single heat dissipation duct in the electrical compartment, the cabin is prone to local overheating under long-term operation. Each electrical component has an operating temperature limit, which is not conducive to the normal operation of the vehicle. Therefore, it is urgent to design an electrical compartment with stronger heat dissipation function to solve the heat dissipation problem in the cabin. Utility Model Content

[0005] An electrical compartment of a reach-forklift with multiple heat dissipation ducts comprises an enclosure that semi-encloses a seat, an end plate arranged on the enclosure, and an electrical compartment arranged on the end plate, wherein the electrical compartment is formed by an instrument panel located at the front end of the seat, a long cover plate located at the proximal end of the side of the seat, a glass baffle plate located at the far end of the side of the seat, a guard plate and an end plate located behind the seat; a first fan assembly is arranged in the electrical compartment, a first heat dissipation grille is arranged on the inner side of the long cover plate, and a fifth heat dissipation grille is arranged on the connecting side of the long cover plate and the enclosure plate; a second heat dissipation grille is arranged on the outer side of the glass baffle plate; and a fourth heat dissipation grille is arranged on the instrument panel.

[0006] Furthermore, an elbow pad is provided in the middle of the long cover plate, and the first heat dissipation grille includes a first grid area located in front of the elbow pad and a second grid area located in the rear of the elbow pad.

[0007] Furthermore, the second heat dissipation grille includes a third grille area and a fourth grille area arranged on both sides of the second fan assembly.

[0008] Furthermore, a third heat dissipation grille is provided on the inner side of the guard plate.

[0009] Furthermore, the second fan assembly includes at least two fans connected in parallel.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model forms a circumferential heat dissipation channel by opening a new second heat dissipation grille and a second fan assembly on the glass baffle, opening a first heat dissipation grille on the inner side of the long cover plate, and opening a third heat dissipation grille on the guard plate, and combining the original fifth heat dissipation grille and the fourth heat dissipation grille, and forming three main convection air ducts in the electrical cabin by combining the first fan assembly (inside the cabin) and the second fan assembly (outside the cabin), which greatly improves the air intake and exhaust capacity of the electrical cabin and ensures normal operation at a higher ambient temperature. The air duct is reasonably set, and a natural heat dissipation air duct that meets forced air cooling is established and guided to avoid internal air flow turbulence.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In the description of the present utility model, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.

[0021] See also Figure 1-6 In this embodiment, an electrical compartment of a reach-forklift with multiple heat dissipation ducts comprises a panel 2 that half surrounds a seat 1, an end plate 3 disposed on the panel 2, and an electrical compartment 4 disposed on the end plate 3. The electrical compartment 4 is formed by a dashboard 5 located at the front end of the seat 1, a long cover plate 10 located at the proximal end of the side of the seat 1, a glass baffle 6 located at the far end of the side of the seat 1, a guard plate 7 located behind the seat 1, and the end plate 3. An electrical control assembly 17 and a first fan assembly 8 are disposed in the electrical compartment 4. A first heat dissipation grille is disposed on the inner side of the long cover plate 10, and a fifth heat dissipation grille 18 is disposed on the connecting side of the long cover plate 20 and the panel 2. A second heat dissipation grille is disposed on the outer side of the glass baffle 6. A fourth heat dissipation grille 19 is disposed on the instrument panel 5. The heat generated by the operation of the electrical control assembly 17 is the main cause of the high temperature in the compartment. The first fan assembly 8 is connected to one side of the electrical control assembly 17 to absorb and dissipate air. The blowing direction of the first fan assembly 8 is the same as that of the guide groove of the electrical control assembly 17. A second fan assembly 9 is provided on the outside of the glass baffle 6 to strengthen the air convection between the cabin and the outside. Through the arrangement of the various heat dissipation grilles and fan assemblies, three main convection air ducts are formed in the electrical cabin 1, wherein the first heat dissipation assembly is arranged at one end close to the fifth heat dissipation grille 18, the first air duct blows from the fifth heat dissipation grille 18 to the fourth heat dissipation grille 19, the second air duct blows from the fifth heat dissipation grille 18 to the second heat dissipation grille, and the third air duct blows from the fifth heat dissipation grille 18 to the first heat dissipation grille. The three-way convection air duct greatly improves the air intake and exhaust capacity of the electrical cabin, ensuring normal operation even at a higher ambient temperature.

[0022] Furthermore, a third heat dissipation grille 16 is provided inside the guard plate 7 .

[0023] Furthermore, the second fan assembly 9 includes at least two fans connected in parallel, which enhances the exhaust and heat dissipation in the cabin.
