Description

Technical Field

[0001] The invention relates to a single-hole heat exchanger. Background Art

[0002] A heat exchanger (also known as a heat exchanger or heat exchange equipment) is a device used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements. It is an industrial application of convective heat transfer and heat conduction. Heat exchangers can be classified in different ways. Based on their operating process, they can be divided into three categories: partitioning type, hybrid type, and thermal storage type (or regenerative type). Based on the compactness of their surface, they can be divided into compact and non-compact types.

[0003] During the installation process, existing heat exchangers have problems such as low installation efficiency and poor waterproofness, and the heat exchanger after installation also has low heat exchange efficiency. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the object of the present invention is to provide a single-hole heat exchanger with high installation efficiency, strong waterproofness and high heat exchange efficiency.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] A single-hole heat exchanger includes an exhaust fan assembly, a heat exchange core assembly connected to the exhaust fan assembly, and a through-wall exhaust pipe assembly connected to the heat exchange core assembly. The exhaust fan assembly includes a motor bracket exhaust pipe and an exhaust fan front cover installed in front of the motor bracket exhaust pipe. The heat exchange core assembly includes a heat exchange core, a fixed bracket arranged at the rear of the heat exchange core, and a primary filter arranged in front of the heat exchange core and behind the fixed bracket. The through-wall exhaust pipe assembly includes a heat exchange core exhaust pipe and a waterproof silicone sleeve inserted into the outside of the heat exchange core exhaust pipe and installed in the wall. The heat exchange core assembly and the motor bracket exhaust pipe are accordingly installed in the heat exchange core exhaust pipe.

During the operation of the ventilation equipment, when the airflow passes through the heat exchange core of the above structure, the diversity of the airflow flow paths can be increased and the contact area between the airflow and the heat exchange core can be increased, thereby ultimately improving the heat exchange efficiency.

[0008] Furthermore, the inner side of the first box body container is integrally formed with one or more protruding columns, and the protruding columns are evenly distributed on the inner side of the first box body container. The ceramic protective layer is composed of one or more arc-shaped sheets separated by the protruding columns.

The second box container is covered with thermal insulation cotton, and a bracket is provided at the mesh holes of the mesh rack. The bracket is provided with more than one group and is correspondingly installed in the mesh holes of the mesh rack. A heat exchange core is installed on the bracket. During the operation of the ventilation equipment, when the airflow passes through the heat exchange core of the above structure, the diversity of the airflow flow path can be increased and the contact area between the airflow and the heat exchange core can be increased, thereby ultimately improving the heat exchange efficiency.

[0010] Preferably, the heat exchange core includes more than one second box container arranged in a stacked manner, and more than one layer of mesh frames installed in the second box container, and a mesh cover installed at the opening of the second box container. The bottom of the second box container is provided with a clamping head, and the top is provided with a clamping slot adapted to the clamping head. The second box container is covered with thermal insulation cotton, and the mesh holes of the mesh frame are provided with a bracket. The bracket is provided with more than one group and is correspondingly installed in the mesh holes of the mesh frame. A heat exchange core is installed on the bracket. During the operation of the ventilation equipment, when the airflow passes through the heat exchange core of the above structure, the diversity of the airflow flow path can be increased and the contact area between the airflow and the heat exchange core can be increased, thereby ultimately improving the heat exchange efficiency. In addition, the assembled structure can increase the selectivity of replacing heat materials.

[0011] Furthermore, the mesh holes of the mesh frame and the mesh cover are both circular mesh holes, the mesh holes of the mesh frame and the mesh cover have the same aperture, the heat exchange core is spherical, the diameter of the heat exchange core is larger than the mesh hole diameter of the mesh frame, each group of the brackets is composed of four flat cylinders whose back sides are integrally formed with the mesh inner wall of the mesh frame, and the top of the flat cylinder is provided with a receiving surface, which fits with the surface of the heat exchange core, and the heat exchange core is a round ceramic sphere with a diameter ranging from 5mm to 100mm; the second box container is round and made of plastic; the number of flat column brackets in each group in the second box container can be selected from 3 to 100; the box container unit groups are combined in a snap-fit structure.

[0012] Furthermore, the motor bracket exhaust pipe includes a motor bracket and a motor fan installed in the motor bracket, and the exhaust fan front cover includes a front cover assembled on the front of the motor bracket, an automatic shutter arranged in the middle of the front cover, and a decorative panel installed on the front cover.

[0013] Furthermore, the waterproof silicone sleeve includes a tube body, a flange column body mounted on the end of the tube body, and a flange plate integrally formed at the end of the flange column body, the flange column body has more than one circle of annular grooves arranged at intervals, the flange plate is an annular protrusion with an outer diameter larger than the flange column body, the flange plate has an annular groove adjacent to the flange column body facing inward, and the flange plate is inclined inwardly toward the outside.

[0014] Preferably, an exhaust hood is installed at the end of the through-wall exhaust pipe assembly.

[0015] The beneficial effects of the present invention are:

[0016] 1. During the installation of the ventilation equipment, especially when working at high altitudes, tool-free installation from indoors to outdoors is achieved, which improves installation efficiency and reduces installation costs. The silicone sleeve waterproof design improves the sealing between the sleeve and the wall hole to achieve a waterproof effect. 2. During the operation of the ventilation equipment, when the airflow passes through the heat exchange core of the above structure, it can increase the diversity of airflow paths and increase the contact area between the airflow and the heat exchange material, ultimately improving the heat exchange efficiency. 3. In the non-working state, the shutters will be closed to prevent foreign objects from entering the room from the outside. The difference between the forward and reverse air volume values is small during normal use, ensuring that the heat exchange efficiency is at a high level during heat exchange applications. The distinction between functional modes is achieved through LED color display, which greatly improves the customer experience. BRIEF DESCRIPTION OF THE DRAWINGS
