Antecedentes da Invenção Background of the Invention
[0002] Veículos motorizados possuem um sistema de arrefecimento do motor, onde um fluido passa através da carcaça do motor, retirando o calor e conduzindo-o para outro ambiente, geralmente dissipando esse calor para o ambiente externo do veículo. Para veículos de transporte de passageiro, esse calor pode ser aproveitado para promover a climatização do ambiente interno do veículo, aquecendo ar, sendo ainda possível utilizar esse calor para desembaçar ou degelar os vidros quando necessário. [0002] Motor vehicles have an engine cooling system, where a fluid passes through the engine housing, removing heat and conducting it to another environment, generally dissipating this heat to the vehicle's external environment. For passenger transport vehicles, this heat can be used to promote the air conditioning of the vehicle's internal environment, heating the air, and it is also possible to use this heat to demist or defrost the windows when necessary.
[0003] Contudo, em veículos de transporte de passageiros, como ônibus, microônibus, entre outros, os componentes que distribuem a água aquecida do motor para as diversas regiões da carroceria ficam distribuídos pelo compartimento do veículo onde é posicionado o motor, conhecido como cofre do motor, de modo que a fabricação do veículo, bem como sua manutenção, se tornam mais complexas e demoradas, para promover a associação desses múltiplos dispositivos que ficam espaçados. Ainda, múltiplos equipamentos acabam por ocupar espaço excessivo no cofre do motor, dificultando a distribuição dos demais equipamentos. [0003] However, in passenger transport vehicles, such as buses, minibuses, among others, the components that distribute the heated water from the engine to the various regions of the body are distributed by the vehicle compartment where the engine is positioned, known as the engine compartment, so that the manufacture of the vehicle, as well as its maintenance, become more complex and time-consuming, to promote the association of these multiple devices that are spaced apart. Also, multiple pieces of equipment end up taking up excessive space in the engine bay, making it difficult to distribute other pieces of equipment.

[0028] In a first object, the present invention presents a device for distributing engine cooling fluid for a passenger transport vehicle, said device comprising a single block (1) associated with a passage for engine cooling fluid vehicle and communicating with at least one thermal equipment.
[0029] Para fins da presente invenção, o equipamento térmico ao qual o bloco único (1) é associado visa promover o aquecimento de ao menos uma região ou parte do veículo. [0029] For the purposes of the present invention, the thermal equipment to which the single block (1) is associated aims to promote the heating of at least one region or part of the vehicle.
[0030] O bloco único (1) desvia uma parcela de fluido de arrefecimento para alimentar ao menos um equipamento térmico do veículo e retorna esse fluido ao motor. [0030] The single block (1) diverts a portion of coolant to feed at least one thermal equipment of the vehicle and returns this fluid to the engine.
[0031] Em uma concretização, o bloco único (1) é associado a ao menos um convector. O convector pode receber outros nomes na técnica, mas promovendo o mesmo efeito prático, é um componente de calefação do veículo, que visa utilizar o calor do fluido de arrefecimento do motor para aquecer o ar do compartimento de passageiros do veículo, climatizando assim o ambiente para uma temperatura mais confortável aos passageiros quando necessário seu aquecimento.

[0033] Em uma concretização, o bloco único (1) é comunicante com dois ou mais equipamentos térmicos do veículo, apresentando qualquer combinação de convectores e degeladores, podendo apresentar mais de um equipamento de cada tipo e/ou não apresentar um equipamento entre esses citados, mas outro distinto. Para fins de exemplificação, em uma concretização onde o veículo ao qual o bloco único (1) é associado é um ônibus de dois andares, o bloco único (1) é associado a um degelador, um convector de piso inferior e um convector de issoo superior. [0033] In one embodiment, the single block (1) communicates with two or more thermal equipment of the vehicle, having any combination of convectors and defrosters, and may have more than one piece of equipment of each type and/or not have one piece of equipment among these cited, but a different one. For exemplifying purposes, in an embodiment where the vehicle to which the single block (1) is associated is a double-decker bus, the single block (1) is associated with a defroster, a lower floor convector and an iso convector higher.
[0034] O bloco único (1) compreende ao menos uma entrada (3) de fluido de arrefecimento aquecido, vindo do motor do veículo, e compreende ao menos uma saída principal (2) de fluido de arrefecimento, que retorna ao motor do veículo. Em uma concretização, a entrada (3) e a saída principal (2) estão dispostas em laterais opostas do bloco único (1). A entrada (3) e a saída principal (2) são conectadas por meio de mangueiras ao motor do veículo e permitem a passagem do fluido de arrefecimento do motor. Ainda, a entrada (3) e a saída principal (2) compreendem uma válvula de fechamento cada uma, que, quando fechadas, impedem a passagem de fluido de arrefecimento para a instalação ou manutenção dos demais componentes do bloco único (1) e dos equipamentos térmicos.

[0039] The single block (1) allows a flow of coolant from the vehicle's engine inside it between the inlet (3) and the main outlet (2). The valve (6) allows or prevents a part of the coolant flow between the outlet (2) and the inlet (3) to leave the single block (1) to access a thermal equipment through the delivery channel (4). Also, the valve (6) allows or prevents that part of the cooling fluid from returning from the thermal equipment through the return channel (5) and accessing the flow of fluid from the single block (1).
[0040] Uma vez que o bloco único (1) promove comunicação com os demais equipamentos térmicos, uma parcela deste fluxo originado do motor é desviada para alimentar os ditos equipamentos. A regulagem da vazão dessa parcela do fluxo principal é feita por meio de cada válvula (6). [0040] Since the single block (1) promotes communication with the other thermal equipment, a portion of this flux originating from the motor is diverted to feed said equipment. The regulation of the flow of this part of the main flow is done through each valve (6).
