Description

Technical Field

[0001] The utility model relates to the field of refrigeration equipment wiring harnesses, and more specifically, to a wiring harness assembly for refrigeration equipment. Background Art

[0002] Refrigeration equipment wiring harness is a wire harness used to connect various electrical components and assemblies in refrigeration equipment. It is usually composed of multiple wires, insulation materials, sheaths and connectors. The function of the wiring harness is to connect various parts of the refrigeration equipment, such as the compressor, condenser, evaporator, controller, etc., to ensure the transmission of current and signals. It is essential to the normal operation of the refrigeration equipment, because any wiring harness failure may cause the equipment to malfunction or even damage it.

[0003] Existing wiring harness assemblies for refrigeration equipment only have simple insulating protective covers, which can easily cause water vapor to wet the internal wires under low temperature conditions, causing the refrigeration equipment to fail to operate, and the moisture-proof effect is poor; in addition, heat is easily accumulated inside the wiring harness, and the simple protective cover is difficult to resist the damage caused by the large amount of internal heat energy. Sometimes, it may be affected by the refrigeration equipment, resulting in the external environment being mostly low temperature. The external low temperature will affect the material of the internal structure of the wiring harness, resulting in poor high and low temperature resistance of the wiring harness. In view of this, we propose a wiring harness assembly for refrigeration equipment. Utility Model Content

[0026] See also Figure 1-5 ,The utility model provides a technical solution:

[0027] A wiring harness assembly for refrigeration equipment, comprising a moisture-proof component 1 and a heat-insulating component 2;

[0028] Specifically, the moisture-proof member 1 includes a plurality of wires 101, the circumferential outer walls of the plurality of wires 101 are sleeved with an insulating sleeve 102, the circumferential outer walls of the insulating sleeve 102 are bonded with a drying belt 103 by adhesive, the circumferential outer walls of the insulating sleeve 102 are sleeved with a moisture-proof film 104, and the circumferential outer walls of the moisture-proof film 104 are sleeved with a temperature-conducting sleeve 105. The drying belt 103 absorbs water vapor, and the heat generated by the wires 101 is used to heat dry the drying belt 103. With the insulation effect of the moisture-proof film 104, the internal space will not be wetted by water vapor generated by the temperature difference between cold and hot or water vapor from other sources, thereby effectively playing a moisture-proof and humidity-proof role.

[0029] Furthermore, the thermal insulation component 2 includes a heat dissipation sleeve 201 sleeved on the circumferential outer wall of the thermal conductive sleeve 105, the circumferential inner wall of the heat dissipation sleeve 201 is integrally formed with a plurality of convex strips 206, the top surface of the convex strips 206 is adhesively bonded with a thermal conductive strip 208, the circumferential outer wall of the heat dissipation sleeve 201 is adhesively bonded with a plurality of rubber strips 202, the side wall of the rubber strip 202 is adhesively bonded with a heat dissipation sleeve 203, the circumferential outer wall of the heat dissipation sleeve 203 is adhesively bonded with a reinforced steel wire mesh 204, the reinforced steel wire mesh 204 can enhance the hardness of the wiring harness component and prevent collision, the circumferential outer wall of the reinforced steel wire mesh 204 is adhesively bonded with a wear-resistant layer 205, the wear-resistant layer 205 is resistant to friction and aging, and plays a role in protecting the interior of the wiring harness component, the thermal insulation component 2 transfers the heat generated by the wire 101 to the thermal conductive strip 208 through the thermal conductive sleeve 105, and further transfers the heat to The heat is stored in the heat dissipation sleeve 201, and part of the heat is stored on the convex strip 206 on the inner wall of the circumference of the heat dissipation sleeve 201, and the other part of the heat is transferred to the space between the multiple rubber strips 202 through the heat dissipation sleeve 201, and the heat dissipation sleeve 203 connected to the rubber strip 202 continues to transfer the heat to the outside. When the wiring harness assembly is used on refrigeration equipment, it is affected by the refrigeration equipment, and the low temperature generated will be transferred to the inside of the wiring harness assembly through the wear-resistant layer 205 until it meets the heat in the space between the multiple rubber strips 202, thereby achieving a cold and hot balance. When the low temperature continues to transfer to the inside and reaches the inside of the heat dissipation sleeve 201, the heat of the convex strip 206 will continue to balance with the low temperature, thereby achieving a heat preservation effect. When the internal temperature of the wiring harness assembly is high, the heat is dissipated outwardly. In the external ultra-low temperature environment, the temperature can be neutralized by itself, so that the wiring harness assembly has good high and low temperature resistance.

[0030] It is worth noting that, in order to achieve a good heat dissipation effect, a groove space 207 is formed between a plurality of adjacent convex strips 206, the heat dissipation sleeve 201 and the convex strips 206 are made of glass fiber, and the temperature conductive sleeve 105 and the heat conductive strips 208 are made of thermal conductive silicone grease.

[0031] It is worth noting that, in order to improve the moisture absorption effect, the drying belt 103 is made of non-woven fabric and the moisture-proof film 104 is made of PE material.

[0032] In addition, in order to provide a buffer space to resist the invasion of low temperature, the heat dissipation sleeve 203 is made of butyl rubber. The heat dissipation sleeve 203 is connected to the heat dissipation sleeve 1 201 through multiple rubber strips 202, and a heat preservation space is formed between the multiple rubber strips 202.

[0033] Finally, in order to make the outer material of the wiring harness assembly wear-resistant and pressure-resistant, the wear-resistant layer 205 is made of polyurethane, and the reinforced steel mesh 204 is formed by woven steel wires.

[0034] Working principle: When the device is required to work, the drying belt 103 absorbs water vapor, and the heat generated by the wire 101 is used to dry the drying belt 103, and the moisture-proof film 104 is used to isolate the internal space, so that the water vapor generated by the temperature difference between hot and cold or other sources of water vapor will not wet the wire 101. When the wire 101 generates a lot of heat, the heat generated by the wire 101 is transferred to the heat-conducting strip 208 through the thermal conductive sleeve 105, and further transferred to the heat dissipation sleeve 201 through the heat-conducting strip 208, and a part of the heat is stored in the circumference of the heat dissipation sleeve 201. On the convex strips 206 of the inner wall, another part of the heat is transferred to the space between the multiple rubber strips 202 through the heat dissipation sleeve 1 201, and the heat dissipation sleeve 203 connected to the rubber strips 202 continues to transfer the heat to the outside. When the wiring harness assembly is used on refrigeration equipment, the low temperature generated by the refrigeration equipment will be transferred to the inside of the wiring harness assembly through the wear-resistant layer 205 until it meets the heat in the space between the multiple rubber strips 202, thereby achieving the effect of cold and heat balance. When the low temperature continues to transfer to the inside and reaches the inside of the heat dissipation sleeve 1 201, the heat of the convex strips 206 will continue to balance with the low temperature.
