Description

Technical Field

[0001] This utility model relates to the field of cold storage and insulation boxes, and more specifically, to a cold storage and insulation box device with a layout of air duct structure. Background Technology

[0002] Cold storage insulated boxes, as a highly efficient logistics technology, occupy an important position in the cold chain logistics field due to their unique advantages. These boxes offer flexible designs and diverse sizes to meet the transportation needs of goods of varying sizes. Simultaneously, their excellent insulation performance ensures the stability of goods quality during transportation, making them particularly suitable for long-distance or short-distance transportation of small batches of high-quality goods. Cold storage insulated boxes not only improve logistics efficiency but also reduce cargo damage caused by temperature fluctuations, becoming an indispensable part of the modern cold chain logistics system.

[0003] The existing technology still has the following drawbacks:

[0004] Previous cold chain containers used refrigeration on both sides of the interior, with evaporators installed on the side walls. In actual operation, this created an inverted triangular area inside the container, where the upper and middle parts were warmer than other parts, resulting in uneven cooling and affecting the overall cooling performance of the container.

[0005] Therefore, we have made improvements to this and proposed a cold storage and insulation box device with a layout of air duct structure. Utility Model Content

[0006] The purpose of this invention is to address the problem of uneven cooling effect, which affects the overall cooling performance of the cabinet.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] A cold storage and insulation box device with a layout of air duct structure is proposed to improve the above-mentioned problems.

[0009] The specific details of this utility model are as follows:

[0010] The device includes an insulated box, which has two sets of evaporators symmetrically arranged inside. Each set of evaporators has an air blowing component on one side to make the cooling effect inside the insulated box more uniform. The air blowing component is equipped with a control component to adjust the air volume.

[0011] The evaporator is fixedly installed inside the insulation box, and there is a gap between the evaporator and the inner side wall of the insulation box, and a gap between the evaporator and the inner top wall of the insulation box.

[0012] The air blowing assembly includes a fan fixedly installed on the outer wall of the insulation box, and an air supply pipe is installed at the output end of the fan, with multiple air outlets opened on the air supply pipe.

[0013] As a preferred technical solution of this utility model, the control component includes a base fixedly disposed on the top of the air outlet, a slide bar slidably connected inside the base, and the slide bar being marked with a scale.

[0014] As a preferred technical solution of this utility model, the air supply pipe penetrates through the insulation box and extends into the interior of the insulation box, and the air supply pipe is located between the evaporator and the inner wall of the insulation box.

[0015] As a preferred technical solution of this utility model, a fixing ring is sleeved on the outside of the fan, and a support column is fixedly installed on the outside of the fixing ring. The other end of the support column is bolted to the outer wall of the insulation box.

[0016] As a preferred technical solution of this utility model, a connecting block is sleeved on the outer side of the air duct, the connecting block is located inside the insulation box, and is fixedly connected to the side wall of the insulation box by bolts.

[0017] As a preferred technical solution of this utility model, the slide bar has multiple sets of circular grooves corresponding to the air outlet, and the slide bar passes through the heat preservation box and extends to the outside of the heat preservation box.

[0018] As a preferred technical solution of this utility model, the multiple sets of air outlets are evenly distributed on the air supply pipe, and the size of the multiple sets of air outlets varies with the distance from the fan. The closer to the fan, the smaller the air outlet.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In the solution of this utility model:

[0021] 1. Through the air blowing component, since there is a one-centimeter gap between the evaporator and the inner wall of the insulation box, and a gap between the evaporator and the inner top wall of the insulation box, the cold air between the evaporator and the inner wall of the insulation box can be blown towards the inner top wall of the insulation box through the air duct. This cools down the inverted triangular area at the top of the insulation box where the temperature is high, making the temperature distribution inside the insulation box more uniform and improving the overall cooling effect of the insulation box.

[0022] 2. With the control components in place, the slider can be manually pulled out during use. The slider slides within the base, and its position changes the effective ventilation area of ​​the air outlet. Since the slider is marked with scales, the user can precisely control the movement distance of the slider according to the scales, thereby accurately adjusting the size of the air outlet.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0031] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0032] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] like Figure 1 and Figure 2As shown, this embodiment proposes a cold storage and heat preservation box device with a layout air duct structure, including a heat preservation box 1. Two sets of evaporators 2 are symmetrically arranged inside the heat preservation box 1. Each set of evaporators 2 has an air blowing component 3 on one side to make the cooling effect inside the heat preservation box 1 more uniform. The air blowing component 3 is equipped with a control component 4 to adjust the air volume.

[0035] like Figure 2 As shown, the evaporator 2 is fixedly installed inside the insulation box 1. There is a gap of one centimeter between the evaporator 2 and the inner side wall of the insulation box 1, and there is also a gap between the evaporator 2 and the inner top wall of the insulation box 1.

[0036] like Figure 3 As shown, the air blowing assembly 3 includes a fan 301 fixedly mounted to the outer wall of the insulation box 1. An air duct 302 is installed at the output end of the fan 301, and multiple air outlets 303 are provided on the air duct 302. In use, because there is a one-centimeter gap between the evaporator 2 and the inner wall of the insulation box 1, and a gap between the evaporator 2 and the inner top wall of the insulation box 1, the air duct 302 can blow the cold air between the evaporator 2 and the inner wall of the insulation box 1 towards the inner top wall of the insulation box 1. This cools the inverted triangular area with a higher temperature at the top of the insulation box 1, making the internal temperature distribution of the insulation box 1 more uniform and improving the overall cooling effect of the insulation box 1.

[0037] like Figure 4 and Figure 5 As shown, the control component 4 includes a base 401 fixedly mounted on the top of the air outlet 303. A slider 402 is slidably connected within the base 401, and the slider 402 is marked with graduations. In use, the slider 402 is manually pulled out, causing it to slide within the base 401. The change in its position alters the effective ventilation area of ​​the air outlet 303. Because the slider 402 is marked with graduations, the user can precisely control the movement distance of the slider 402 according to the graduations, thereby accurately adjusting the size of the air outlet 303.

[0038] like Figure 2 and Figure 3 As shown, the air duct 302 passes through the insulation box 1 and extends into the interior of the insulation box 1. The air duct 302 is located between the evaporator 2 and the inner wall of the insulation box 1. Through the air duct 302, the cold air between the evaporator 2 and the inner wall of the insulation box 1 can be blown towards the inner top wall of the insulation box 1.

[0039] like Figure 1 and Figure 3As shown, a fixing ring 5 is sleeved on the outside of the fan 301, and a support column 6 is fixedly installed on the outside of the fixing ring 5. The other end of the support column 6 is bolted to the outer wall of the insulation box 1. One end of the support column 6 is fixedly connected to the outside of the fixing ring 5, and the other end is bolted to the outer wall of the insulation box 1, forming a stable support structure.

[0040] like Figure 3 As shown, a slider 7 is sleeved on the outside of the air supply pipe 302. The connecting block 7 is located inside the insulation box 1 and is fixedly connected to the side wall of the insulation box 1 by bolts. By setting the connecting block 7, the position of the air supply pipe 302 can be fixed, which can effectively reduce the shaking of the air supply pipe 302 and facilitate its use.

[0041] like Figure 1 , Figure 4 and 5 As shown, the slide bar 402 has multiple sets of circular grooves corresponding to the air outlet 303. The slide bar 402 passes through the insulation box 1 and extends to the outside of the insulation box 1. In use, since the slide bar 402 passes through the insulation box 1 and extends to the outside of the insulation box 1, it can be pulled out more conveniently to adjust the size of the air outlet 303.

[0042] like Figure 3 As shown, multiple sets of air outlets 303 are evenly distributed on the air duct 302. The size of the multiple sets of air outlets 303 varies with the distance from the fan 301. The closer to the fan 301, the smaller the air outlet 303. Since the air duct 302 is too long, setting air outlets 303 of different sizes can ensure that the air volume at different locations is roughly equal.

[0043] Specifically, when using the cold storage and insulation box device with this air duct structure: (e.g.) Figure 1 , Figure 2 and Figure 3 As shown, due to the one-centimeter gap between the evaporator 2 and the inner wall of the insulation box 1, and the gap between the evaporator 2 and the inner top wall of the insulation box 1, the cold air between the evaporator 2 and the inner wall of the insulation box 1 can be blown towards the inner top wall of the insulation box 1 through the provided air duct 302. This cools the inverted triangular area with a higher temperature at the top of the insulation box 1, making the internal temperature distribution of the insulation box 1 more uniform and improving the overall cooling effect of the insulation box 1. Figure 4 and Figure 5 As shown, the slider 402 is manually pulled out and slides within the base 401. The change in its position will change the effective ventilation area of ​​the air outlet 303. Since the slider 402 is marked with scales, the user can precisely control the movement distance of the slider 402 according to the scales, and thus accurately adjust the size of the air outlet 303. The slider 402 passes through the insulation box 1 and extends to the outside of the insulation box 1, which can be pulled out more conveniently to adjust the size of the air outlet 303.

[0044] All technical features in this embodiment can be freely combined according to actual needs.

[0045] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
