Description

Technical Field

[0001] The utility model belongs to the technical field of refrigeration equipment, and in particular relates to an embedded integrated high-top refrigerated truck refrigeration machine structure. Background Art

[0002] Common types of refrigeration machines for van refrigerated trucks include mechanical refrigeration and liquid nitrogen or dry ice refrigeration.

[0003] A more common mechanical refrigeration method is to circulate low-temperature refrigerant between the compressor, condenser, expansion valve, and evaporator through a refrigeration unit installed on the top of the vehicle, thereby cooling the interior of the vehicle. The refrigeration system consists of refrigerant and four major components, namely the condenser, compressor, expansion valve, and evaporator. This structure uses a vapor compression cycle, which means that when a liquid evaporates into a gas under a certain pressure, it absorbs heat, and when the gas condenses into a liquid, it releases heat. The compressor compresses the low-pressure gaseous refrigerant in the evaporator into high-pressure steam, which flows to the condenser, dissipates heat in the condenser, and becomes liquid. The pressure is then reduced by the expansion valve and flows to the evaporator, where it absorbs heat and becomes gaseous, thereby cooling the interior of the vehicle.

[0004] Refrigeration units are categorized into two types: standalone and dependent. Standalone units have their own independent power system, independent of the vehicle's engine for cooling, and are typically used in refrigerated trucks with larger cargo compartments. Dependent units lack their own power; the refrigeration compressor is driven by the vehicle's engine, and are typically used in smaller refrigerated trucks.

[0005] The installation position and size of existing refrigerators cannot adapt to different vehicle models. The gap between the cargo compartment and the front of some vehicle models is small, and the refrigerator cannot adapt to its structural layout, which limits its use. Utility Model Content

[0006] The purpose of this utility model is to:

[0007] In order to solve the problem that the installation position and size of the refrigeration machine structure of the prior art refrigeration vehicle cannot be flexibly adapted to different vehicle models, an embedded integrated high-top refrigeration machine structure is provided.

[0008] The technical solutions adopted in this utility model are as follows:

[0009] A refrigeration unit structure embedded in an integrated high-top refrigerated truck includes a compartment, the compartment including a top panel and side panels, an integral foaming insulation cavity is provided between the side panel at one end of the compartment and the top panel, the integral foaming insulation cavity is a compartment panel foaming molding structure, an inner concave cavity plate is installed in the integral foaming insulation cavity, a condenser is installed in the inner concave cavity plate, and an evaporator connected to the condenser is installed inside the compartment.

[0010] Furthermore, embedded connectors are installed in the top plate and the side plates, and the inner concave mold cavity plate is fixedly connected to the top plate and the side plates via the embedded connectors.

[0011] Furthermore, the cross section of the inner concave mold cavity plate is an L-shaped structure.

[0012] Furthermore, the condenser and the evaporator are connected to each other via bolts and a cooling machine pipeline.

[0013] Furthermore, the condenser includes a parallel flow mechanism, which is installed in the integral foaming and thermal insulation mold cavity, and the other end of the condenser away from the parallel flow mechanism is installed inside the compartment.

[0014] Furthermore, a top cover is installed on the top of the integral foaming and thermal insulation cavity, and a lifting ring is provided on the top cover.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] This utility model incorporates a partially recessed condenser and a top-mounted embedded design, allowing the refrigeration unit's installation location and size to accommodate the cabs of more and larger, high-roof, two-bedroom vehicles. By embedding the condenser within the vehicle, only the parallel flow portion of the condenser is exposed on the front panel of the refrigerated compartment after the refrigeration unit is installed. This significantly reduces the space required for the condenser to protrude from the front panel. This solves the current problem of conventional refrigeration units, where the entire condenser is exposed outside the vehicle compartment after installation, occupying a significant amount of space between the refrigerated compartment and the cab. This can lead to interference between the cab and the refrigeration unit in medium and heavy-duty refrigerated trucks with exceptionally high cab roofs, as well as the need to cut and patch the cab. This structure expands the space available for the condenser's structural layout, allowing for more rational layout of the condenser fan, heat exchanger elevation, and other electrical components, resulting in a 15% to 20% increase in cooling capacity.

[0017] The integrated top-mounted embedded refrigeration unit structure of the utility model can realize pressure maintenance, refrigerant filling and completion of debugging before the refrigeration unit is installed on the compartment, which greatly reduces the failure rate of the refrigeration unit and the subsequent maintenance cost.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] A built-in, integrated, high-top refrigerated truck refrigeration unit structure includes a compartment, which includes a top panel 1 and side panels 2. An integral foam insulation cavity 3 is provided between the side panel 2 at one end of the compartment and the top panel 1. The integral foam insulation cavity 3 is a foamed structure of the compartment panel. An inner concave cavity plate 4 is installed within the integral foam insulation cavity 3. A condenser 5 is installed within the inner concave cavity plate 4. An evaporator 6 connected to the condenser 5 is installed inside the compartment. The structural installation method of the utility model is embedded in the top of the refrigerated truck cargo compartment. The structural method is an integrated unit structure. The evaporator 6, the integral foam insulation cavity 3, and the condenser form an integral structure at the front end of the compartment roof. The only exposed part of the refrigeration unit is the parallel flow mechanism of the condenser 5.

[0026] The condenser 5 and the evaporator 6 are connected to each other through the integral foaming insulation cavity 3 (connecting bolts and cooling pipes to each other) to form a whole (including the injection of refrigerant).

[0027] Embedded connectors are installed within the top panel 1 and side panels 2, securing the inner cavity panel 4 to the top and side panels 1 and 2. The corresponding panels are cut from the vehicle body to match the overall foam insulation cavity 3. Steel is pre-embedded in the vehicle body panels to match the cavity. The inner cavity is then secured to the panels (top and front panels), and the evaporator 6 is then attached to the top panel 1.

[0028] Preferably, the cross section of the inner concave mold cavity plate 4 is an L-shaped structure.

[0029] The condenser 5 and the evaporator 6 are connected to each other through bolts and cooling pipes.

[0030] The condenser 5 includes a parallel flow mechanism, which is installed in the integral foaming and thermal insulation cavity 3 , and the other end of the condenser 5 away from the parallel flow mechanism is installed inside the compartment.

[0031] A top cover 7 is installed on the top of the integral foaming insulation cavity 3, which cooperates with the side cover close to the condenser 5 on the side to protect the integral foaming insulation cavity 3 when the installation is completed. At the same time, through holes are opened on the top cover 7 and the side cover for heat dissipation. A lifting ring 8 is provided on the top cover 7 to facilitate the lifting and installation of the refrigerator.

[0032] This utility model partially hides the condenser 5 and embeds it on the top, allowing the installation position and size of the refrigerator to adapt to the cabs of more and larger high-top double-bedroom vehicles. By partially hiding the condenser 5 and embedding it on the top, the structural layout space of the condenser 5 of the refrigeration unit is expanded, and the layout of the condensing fan, heat exchanger elevation angle, and other electrical components can be more rationally optimized, which can achieve a 15% to 20% increase in cooling capacity. The integrated top-mounted embedded refrigerator structure can achieve pressure maintenance, refrigerant filling, and complete debugging before the refrigerator is installed on the cabin, greatly reducing the failure rate of the refrigerator and subsequent maintenance costs.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
