Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration, and particularly relates to a top-mounted integral refrigeration unit housing. Background Art

[0002] Existing cold storage refrigeration units generally adopt wall-mounted or floor-standing refrigeration units. The entire evaporation part of the refrigeration unit is placed inside the cold storage, which occupies a relatively large space in the cold storage. At the same time, since the evaporation part is arranged on one side wall of the cold storage, the sprayed cold air is not evenly distributed; the condensation part of the refrigeration unit is hung on the cold storage panel or placed on the ground on one side of the cold storage, which indirectly or directly increases the floor area. Content of the Utility Model

[0003] The purpose of the utility model is to provide a top-mounted integral refrigeration unit housing. By arranging the refrigeration unit at the top, the floor area can be effectively reduced; by blowing cold air from top to bottom, the cold air in the cold storage can be more evenly distributed; by arranging only a small part of the evaporation part housing inside the cold storage, the usable space of the cold storage can be increased.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions:

[0005] A top-mounted integral refrigeration unit housing includes a main housing with a rectangular shape and an open bottom side. An evaporation part housing is fixedly arranged inside the main housing, and the lower end of the evaporation part housing extends out of the main housing; a condensation part housing is fixed on the right side of the main housing;

[0006] An evaporation air inlet grille hole and an evaporation air outlet grille hole are arranged at the bottom of the evaporation part housing;

[0007] A condensation air inlet grille hole is arranged on the right side wall of the condensation part housing, and condensation air outlet grille holes are arranged on the front side wall and the rear side wall of the condensation part housing.

[0008] During installation, the main housing and the condensation part housing are placed on the top of the cold storage, and the lower end of the evaporator housing penetrates through the upper cold storage panel and extends into the cold storage; the air in the cold storage enters from the evaporation air inlet grille hole, and then after heat exchange by the evaporator, cold air is blown out from the evaporation air outlet grille hole, thereby refrigerating the cold storage.

[0009] The main housing is arranged at the top and most of the evaporator housing is placed outside the cold storage, which can greatly reduce the occupied space of the cold storage, improve the space utilization above the cold storage, and reduce the occupied space on the side of the cold storage; at the same time, the cold air is blown from top to bottom, and the cold air can be more evenly distributed.

[0010] The utility model is further arranged as follows: a distance L is provided between the inner side wall of the main housing and the outer side wall of the evaporation part housing, and the distance L is 40 - 60 mm.

[0011] Through the above technical solution, a heat insulation cavity is formed between the main housing and the evaporation part housing, which can reduce the loss of cold in the evaporation part housing and reduce the heat exchange with the outside world.

[0012] The present utility model is further arranged as follows: A fan mounting plate, an evaporator base, and a support partition are fixedly installed inside the evaporation part housing. The fan mounting plate, the evaporator base, and the support partition divide the evaporation part housing into an evaporation air inlet cavity and an evaporation air outlet cavity; the evaporation air inlet grille holes communicate with the evaporation air inlet cavity, and the evaporation air outlet grille holes communicate with the evaporation air outlet cavity.

[0013] Through the above technical solution, an evaporator can be installed on the evaporator base, and an evaporator fan can be installed on the fan mounting plate. When the evaporator fan works, the air in the evaporation air inlet cavity is sent to the evaporator, and after heat exchange with the evaporator, it becomes cold air and flows out from the evaporation air outlet grille holes.

[0014] The present utility model is further arranged as follows: Two fan mounting holes are arranged in parallel on the fan mounting plate;

[0015] The support partition includes an integrally formed upper support inclined plate, a main support plate, and a lower support cross plate. The lower support cross plate is fixed on the bottom plate of the evaporation part housing;

[0016] A flanging is formed at one end of the evaporator base close to the support partition, and the flanging is pressed against the upper support inclined plate, and the flanging and the upper support inclined plate are fixed by screws.

[0017] Through the above technical solution, the support partition can provide an effective support for the evaporator base, and the evaporator installed on the evaporator base can be made more stable.

[0018] The present utility model is further arranged as follows: An outward flanging is fixed at the bottom of the evaporation part housing, and bolt holes are provided on the outward flanging.

[0019] Through the above technical solution, the outward flanging is fixed on the upper storage board of the cold storage by screws, thereby increasing the installation stability of the evaporation part housing.

[0020] The present utility model is further arranged as follows: An inward flanging is formed at the lower end of the main housing, and the evaporation part housing is fixedly connected to the inward flanging through a connecting plate.

[0021] The present utility model is further arranged as follows: A fan plate frame is fixedly installed inside the condensation part housing, a condensation fan is installed on the fan plate frame, and the fan plate frame divides the condensation part housing into a condensation air inlet cavity and a condensation air outlet cavity; a condenser is fixedly installed in the condensation air inlet cavity, and the condenser faces the condensation fan;

[0022] The lower bottom surface of the condensation part housing is flush with the inward flanging.

[0024] The present utility model is further configured as: a condensing air outlet grille hole is also formed on the upper side wall of the condensing unit housing.

[0025] By arranging the condensing air outlet grille hole above, the heat dissipation effect of the condenser can be further improved.

[0026] The outstanding effect of the present utility model is:

[0027] Compared with the prior art, by arranging the refrigeration unit at the top, the floor area can be effectively reduced; by blowing cold air from top to bottom, the cold air in the cold storage can be more evenly distributed; by arranging only a small part of the evaporation unit housing in the cold storage, the usable space of the cold storage can be increased.

[0041] The following combines the drawings and embodiments to further describe in detail the detailed implementation mode of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0042] The following reference Figures 1 to 5 is used to illustrate the present utility model:

An evaporation unit housing 20 is fixedly arranged inside the main housing 10, and the lower end of the evaporation unit housing 20 extends outside the main housing 10; a condensing unit housing 30 is fixed on the right side of the main housing 10;

[0044] An evaporation air inlet grille hole 201 and an evaporation air outlet grille hole 202 are arranged at the bottom of the evaporation unit housing 20;

[0045] A condensing air inlet grille hole 301 is arranged on the right side wall of the condensing unit housing 30, and condensing air outlet grille holes 302 are arranged on the front side wall and the rear side wall of the condensing unit housing 30.

[0046] During installation, the main housing and the condensing unit housing are placed on the top of the cold storage, and the lower end of the evaporator housing penetrates through the upper storage board of the cold storage and extends into the cold storage; the air in the cold storage enters from the evaporation air inlet grille hole, and then after heat exchange through the evaporator, cold air is blown out from the evaporation air outlet grille hole, thereby refrigerating the cold storage.

[0047] The main housing is set on the top and most of the evaporator housing is placed outside the cold storage, which can greatly reduce the occupied space of the cold storage, improve the space utilization above the cold storage, and reduce the occupied space on the side of the cold storage; at the same time, the cold air is blown from top to bottom, and the cold air can be more evenly distributed.

[0048] As Figure 2 shown, a distance L is provided between the inner side wall of the main housing 10 and the outer side wall of the evaporation unit housing 20, and the distance L is between 40 and 60 mm.

[0049] An insulating cavity is formed between the main housing and the evaporation unit housing, which can reduce the loss of cold in the evaporation unit housing and reduce the heat exchange with the outside.

[0050] Inside the evaporation part housing 20, a fan mounting plate 203, an evaporator base 204, and a support partition plate 205 are fixed. The fan mounting plate 203, the evaporator base 204, and the support partition plate 205 divide the evaporation part housing 20 into an evaporation air inlet chamber 2001 and an evaporation air outlet chamber 2002; the evaporation air inlet grille holes 201 communicate with the evaporation air inlet chamber 2001, and the evaporation air outlet grille holes 202 communicate with the evaporation air outlet chamber 2002.

[0051] An evaporator can be installed on the evaporator base, and an evaporator fan can be installed on the fan mounting plate.

[0055] The support partition plate can provide an effective support for the evaporator base, and can make the evaporator installed on the evaporator base more stable.

[0056] As Figure 3 shown, an outward flanging 206 is fixed at the bottom of the evaporation part housing 20, and bolt holes are provided on the outward flanging 206.

[0057] Through the above technical solution, the outward flanging is fixed on the upper storage board of the cold storage by screws, thereby increasing the installation stability of the evaporation part housing.

[0058] An inward flanging 101 is formed at the lower end of the main housing 10, and the evaporation part housing 20 is fixedly connected to the inward flanging 101 through a connecting plate 21.

[0059] Inside the condensation part housing 30, a fan plate frame 303 is fixed. A condensation fan is installed on the fan plate frame. The fan plate frame 303 divides the condensation part housing 30 into a condensation air inlet chamber 3001 and a condensation air outlet chamber 3002; a condenser is fixed in the condensation air inlet chamber, and the condenser faces the condensation fan;

[0060] The lower bottom surface of the condensation part housing 30 is flush with the inward flanging 101.

[0061] The main housing and the condensation part housing can be placed flat on the upper end of the cold storage, and the force is more evenly distributed.

[0062] A condensation air outlet grille hole 302 is also formed on the upper side wall of the condensation part housing 30.

[0063] By arranging the condensation air outlet grille hole above, the heat dissipation effect of the condenser can be further improved.

[0064] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made.
