Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange, in particular to a heating and ventilation device. Background Art

[0002] At present, the heating and ventilation devices on the market are generally implemented by heat exchangers. Heat exchangers are mostly made of aluminum tubes and fins assembled and welded as an integral structure. The heat exchange area of ​​the aluminum tube and fin heat exchanger is fixed, difficult to disassemble, and cannot be flexibly assembled and assembled, and cannot meet the required heat exchange capacity. Most of the fins are corrugated belt type, and their role in the heat exchange system is to exchange heat with air. Since most heat exchangers work in harsh conditions, it is not easy to disassemble and clean the fins during use, which affects the performance of the heat exchanger and even shortens the service life of the heat exchanger.

[0003] Therefore, how to develop a heat exchanger that is easy to assemble and disassemble, quick to clean, has a long service life, and can flexibly increase or decrease the heat exchange area has become a technical problem that needs to be urgently solved by technical personnel in this field.

[0004] In view of the shortcomings of the above-mentioned scheme in actual production and implementation, it has been revised and improved. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, a heating and ventilation device is specially provided to solve the problem that the current heat exchanger is fixed and welded and cannot be flexibly disassembled and assembled, as well as the problem that it is difficult to clean, affects the performance of the heat exchanger and affects the service life. Utility Model Content

[0006] The technical solution of the utility model is achieved in this way:

[0007] A heating and ventilation device comprises an external frame and a plurality of heat exchangers arranged on the inner side of the external frame, wherein the external frame is used to limit the position of the heat exchanger, the heat exchanger comprises water chambers arranged at left and right ends and a middle lateral support arranged between the two water chambers, a plurality of water pipes are arranged between the two water chambers, a top cover and a bottom cover of the water chamber are respectively provided with a card slot and a card block, the card slot and the card block match, a water inlet and an outlet are arranged on the water chamber, and a positioning side ear is arranged on the side wall of the water chamber.

[0008] The water inlet and outlet of the utility model can be freely combined according to the customer's site requirements, avoiding the limitation of space size and freely selecting the direction and position of the water outlet.

[0009] As a preferred embodiment, the heat exchanger is made of all plastic.

[0010] This utility model patent meets different heat exchange requirements by freely combining heat exchangers and increasing or decreasing the number of heat exchangers. It is combined according to the space and area of ​​the application site to meet different heat exchange requirements. It adopts a full plastic structure, which has the advantages of inhibiting scale formation, no heavy metal ion formation, corrosion resistance, and no water pollution. In addition, the production process consumes less energy, has less environmental pollution, has low production costs, has significant beneficial effects, and is easy to apply and promote.

[0011] The installation and disassembly of the heat exchanger is simple and quick, which greatly improves the efficiency of heat exchanger assembly and maintenance.

[0012] As a preferred embodiment, a frame reinforcement support is provided outside the external frame.

[0013] The frame reinforcement support is arranged longitudinally, which not only strengthens the overall strength of the external frame, but also provides a better limiting effect for the internal heat exchanger.

[0014] As a preferred embodiment, a plurality of middle longitudinal supports are arranged between the middle transverse supports.

[0015] The middle transverse support and the middle longitudinal support together form the middle frame of the heat exchanger.

[0016] As a preferred embodiment, it includes a pipe arrangement support, on which are provided a plurality of grooves for clamping water pipes. The pipe arrangement support is used to limit and arrange the water pipes between the water chambers, and the water pipes are neatly arranged in the longitudinal direction.

[0017] The pipe management support is a support for organizing water pipes. It has several pipe grooves for clamping water pipes. Each water pipe is clamped in the evenly distributed pipe grooves, neatly and not loose. Using it to fix and support the water pipes can effectively prevent the water pipes from sinking due to the weight after being filled with water.

[0018] The working principle of the utility model is to heat or cool the inflowing air to reach the desired ideal temperature through the process of heat exchange between the inflowing air and the water in the heat exchanger. At the same time, if the water in the heat exchanger reaches a certain temperature after heat exchange, the water with heat can be recycled.

[0019] The utility model patent adopts a full plastic structure, and the whole is made of polypropylene material. The full plastic structure has the advantages of inhibiting scale formation, no heavy metal ion formation, corrosion resistance, and no water pollution. It is also easy to clean, not easy to corrode and rust, and extends the service life.

[0020] This solution also changes the fixity of the traditional aluminum tube and fin heat exchanger, which is not easy to increase or decrease the heat exchange area. It is flexible to use and widely used. It can be used not only in industrial heating and ventilation, but also in the air inlet of livestock and poultry houses to process the temperature of fresh air, and can also be used in the air outlet of livestock and poultry houses to recover heat. It can also replace the traditional radiator in the north for heating in winter.

[0021] The beneficial effects of the utility model are:

[0022] 1. The overall structure is fully plastic, which has the advantages of inhibiting scale formation, no heavy metal ion formation, corrosion resistance, and no water pollution.
