Technical Field
[0001] This utility model belongs to the field of heat exchanger technology, and in particular relates to a heat exchange device that is easy to clean. Background Technology
[0002] A heat exchanger is a device that transfers some of the heat from hot air to cold fluid. It is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions, and are also widely used in daily life. However, existing heat exchangers generally have problems such as outdated structure, low heat exchange efficiency, high material consumption, high manufacturing cost, large size, and inconvenient installation and transportation. In particular, the dust in the waste heat can adhere to the fresh air duct, causing cavity blockage, hindering the passage of waste heat and affecting heat exchange efficiency. Utility Model Content
[0003] The main technical problem to be solved by this utility model is to provide a heat exchange device that is reasonably structured, easy and reliable to operate, has high heat exchange efficiency, and is easy to clean.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0005] A heat exchange device that is easy to clean includes a frame, a bottom plate fixedly connected to the bottom of the frame, and a front baffle, a rear baffle, and an upper baffle detachably fixed to the side and top of the frame, respectively. The bottom plate, the front baffle, the rear baffle, and the upper baffle together form a heat exchange chamber, and a heat exchange device is installed inside the heat exchange chamber. Waste heat inlet flange and waste heat outlet flange are installed at both ends of the frame, respectively.
[0006] The following are further optimizations of the above technical solution by this utility model:
[0007] The heat exchange device includes multiple heat exchange bend assemblies, which are arranged in parallel at a certain distance along the vertical direction.
[0008] Further optimization: The heat exchanger bend assembly includes multiple heat exchanger bends, which are arranged at intervals along the horizontal direction.
[0009] Further optimization: An air inlet support plate and an air outlet support plate are fixedly connected to the frame. The air inlet support plate and the air outlet support plate are arranged diagonally. The two ends of the heat exchange bend are fixedly connected to the air inlet support plate and the air outlet support plate, respectively.
[0010] Further optimization: A fresh air inlet flange is fixedly connected to the air inlet support plate, and a fresh air outlet flange is fixedly connected to the air outlet support plate. The fresh air inlet flange is close to the waste heat outlet flange, and the fresh air outlet flange is close to the waste heat inlet flange.
[0011] Further optimization: Multiple supports are installed on the base plate, and the supports are located at the bends near the heat exchanger bends.
[0012] Further optimization: The support includes a column, which is fixedly connected to the base plate. Multiple support plate assemblies are fixedly connected to the column, and the number of support plate assemblies matches the number of heat exchanger bend assemblies.
[0013] Further optimization: The pallet assembly includes two pallets, which are respectively located on two adjacent sides of the column and are fixedly connected to the column.
[0014] Further optimization: Sealing gaskets are installed between the front baffle, rear baffle, and upper baffle and the frame.
[0015] This utility model features a rational design, reasonable structure, low material consumption, low manufacturing cost, compact structure, small size, and convenient installation and transportation. When a large amount of dust accumulates and clogs the heat exchange chamber, the front baffle, rear baffle, and upper baffle can be easily removed for thorough cleaning of the heat exchange device, preventing the dust adhering to the heat exchange device from affecting the normal heat exchange operation. The fresh air inlet flange is close to the waste heat outlet flange, and the fresh air outlet flange is close to the waste heat inlet flange. This allows the fresh air entering from the fresh air inlet flange to first pass through the low-temperature zone during its flow within the heat exchange bend, then gradually heat up, and finally flow out from the high-temperature zone, thus facilitating improved heat exchange efficiency of the equipment.
[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation
[0023] like Figure 1-5As shown, a heat exchange device that is easy to clean includes a frame 1. A base plate 2 is fixedly connected to the bottom of the frame 1. A front baffle 3, a rear baffle 4, and an upper baffle 5 are detachably fixed to the sides and top of the frame 1 by bolts. The base plate 2, the front baffle 3, the rear baffle 4, and the upper baffle 5 together form a heat exchange chamber. A heat exchange device 6 is installed in the heat exchange chamber. Waste heat inlet flange 7 and waste heat outlet flange 8 are installed at both ends of the frame 1, respectively.
[0024] This design allows for easy removal of the front baffle 3, rear baffle 4, and upper baffle 5 when a large amount of soot accumulates on the heat exchanger 6 and clogs the heat exchange chamber. This facilitates thorough cleaning of the heat exchanger 6 and prevents the soot attached to the heat exchanger 6 from affecting the normal heat exchange operation of the equipment.
[0025] In this embodiment, waste heat air is introduced into the heat exchange chamber from the waste heat inlet flange 7 by an induced draft fan, and after heating the heat exchange device 6, it is discharged from the waste heat outlet flange 8, thereby realizing the heating work of the heat exchange device 6.
[0026] Sealing gaskets 11 are provided between the front baffle 3, the rear baffle 4 and the upper baffle 5 and the frame 1, thereby enhancing the sealing effect of the heat exchange chamber.
[0027] The heat exchange device 6 includes three heat exchange bend assemblies, which are arranged in parallel at a certain distance along the vertical direction.
[0028] In addition to this embodiment, the number of heat exchanger bend assemblies can also be two or more.
[0029] The heat exchanger bend assembly includes three heat exchanger bends 601, which are arranged at intervals in the horizontal direction.
[0030] In addition to this embodiment, the number of heat exchanger bends 601 can also be two or more.
[0031] This design increases the contact area between the heat exchanger bend 601 and the hot air, thereby improving the heat exchange efficiency.
[0032] The heat exchanger bend 601 is a metal corrugated pipe, with aluminum corrugated pipe being the preferred choice.
[0033] In addition to this embodiment, the heat exchanger bend 601 can also be a metal finned tube such as an aluminum finned tube or a stainless steel finned tube.
[0034] An air inlet support plate 602 and an air outlet support plate 603 are fixedly connected to the frame 1. The air inlet support plate 602 and the air outlet support plate 603 are arranged diagonally. The two ends of the heat exchange bend 601 are fixedly connected to the air inlet support plate 602 and the air outlet support plate 603 respectively through threaded joints.
[0035] A fresh air inlet flange 9 is fixedly connected to the air inlet support plate 602, and a fresh air outlet flange 10 is fixedly connected to the air outlet support plate 603. This allows fresh air to enter through the fresh air inlet flange 9, exchange heat through multiple heat exchange bends 601, and then be collected from the fresh air outlet flange 10 and delivered to the equipment in use.
[0036] Fresh air inlet flange 9 is close to waste heat outlet flange 8, and fresh air outlet flange 10 is close to waste heat inlet flange 7.
[0037] With this design, the temperature of the waste heat decreases as it flows through the heat exchange chamber. As a result, the fresh air entering from the fresh air inlet flange 9 flows through the heat exchange bend 601, first passing through the low-temperature zone, then gradually heating up, and finally flowing out from the high-temperature zone, which facilitates the improvement of the equipment's heat exchange efficiency.
[0038] In this embodiment, fresh air is introduced from the fresh air inlet flange 9 into the heat exchanger bend 601 by an exhaust fan. After the fresh air in the heat exchanger bend 601 is heated, the hot air is discharged from the fresh air outlet flange 10 for use by the equipment.
[0039] Multiple supports 604 are provided on the base plate 2. The supports 604 are located near the bend of the heat exchange bend 601, thereby providing effective support for the heat exchange bend 601.
[0040] The bracket 604 includes a column 6041, which is fixedly connected to the base plate 2.
[0041] Three support plate assemblies are fixed to the column 6041. The three support plate assemblies are respectively set to correspond to the heat exchange bend 601, thereby forming a layered support for the heat exchange bend 601 and ensuring that the spacing between each pair of heat exchange bend assemblies is consistent.
[0042] In addition to this embodiment, the number of pallet assemblies can also be two or more, and the number of pallet assemblies can match the number of heat exchanger bend assemblies.
[0043] The pallet assembly includes two vertically arranged pallets 6042, which are respectively located on two adjacent sides of the column 6041. The pallets 6042 are fixedly connected to the column 6041 to provide effective support for the heat exchange bend 601.
[0044] In addition to this embodiment, each pallet assembly may also have one pallet 6042, which is fixedly connected to the column 6041 to provide effective support for the heat exchange bend 601.
[0045] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
